Having problem in Technical Documentation Page

i am having a problem in Technical Documentation Page… the error is showing like this Each .nav-link should have an href attribute that links to its corresponding .main-section (e.g. If you click on a .nav-link element that contains the text “Hello world”, the page navigates to a section element with that id)… i had solved it and it also showed a correct sign but now it’s showing a wrong sign … can’t understand what the problem is. HELP PLSS!!..

          <p> JavaScript is a cross-platform, object-oriented scripting language. It is a small and lightweight language. Inside a host environment (for example, a web browser), JavaScript can be connected to the objects of its environment to provide programmatic control over them.</p>

<p>JavaScript contains a standard library of objects, such as Array, Date, and Math, and a core set of language elements such as operators, control structures, and statements. Core JavaScript can be extended for a variety of purposes by supplementing it with additional objects; for example: </p>

        <ul>
          <li>Client-side JavaScript extends the core language by supplying objects to control a browser and its Document Object Model (DOM). For example, client-side extensions allow an application to place elements on an HTML form and respond to user events such as mouse clicks, form input, and page navigation. </li>
          <li>Server-side JavaScript extends the core language by supplying objects relevant to running JavaScript on a server. For example, server-side extensions allow an application to communicate with a database, provide continuity of information from one invocation to another of the application, or perform file manipulations on a server.</li>
        </ul>

      <header>What you should already know</header>
      <p>This guide assumes you have the following basic background:</p>
      <ul>
        <li>A general understanding of the Internet and the World Wide Web (WWW).</li>
        <li>Good working knowledge of HyperText Markup Language (HTML).</li>

      <header>JavaScript and Java</header>
      <p>
        JavaScript and Java are similar in some ways but fundamentally different in some others. The JavaScript language resembles Java but does not have Java's static typing and strong type checking. JavaScript follows most Java expression syntax, naming conventions and basic control-flow constructs which was the reason why it was renamed from LiveScript to JavaScript. 
      </p>
      <p>
        In contrast to Java's compile-time system of classes built by declarations, JavaScript supports a runtime system based on a small number of data types representing numeric, Boolean, and string values. JavaScript has a prototype-based object model instead of the more common class-based object model. The prototype-based model provides dynamic inheritance; that is, what is inherited can vary for individual objects. JavaScript also supports functions without any special declarative requirements. Functions can be properties of objects, executing as loosely typed methods. 
      </p>
      <p>
        JavaScript is a very free-form language compared to Java. You do not have to declare all variables, classes, and methods. You do not have to be concerned with whether methods are public, private, or protected, and you do not have to implement interfaces. Variables, parameters, and function return types are not explicitly typed. 
      </p>
      </section>
      <section class="main-section" id="Hello_world">
      <header>Hello world</header>
      <p>To get started with writing JavaScript, open the Scratchpad and write your first "Hello world" JavaScript code: </p>
      <code>function greetMe(yourName) { alert("Hello " + yourName); }
            greetMe("World");</code>
      <p>
         Select the code in the pad and hit Ctrl+R to watch it unfold in your browser! 
      </p>
      </section>
      <section class="main-section" id="Variables">
      <header>Variables</header>
       <p>You use variables as symbolic names for values in your application. The names of variables, called identifiers, conform to certain rules.</p>

<p>A JavaScript identifier must start with a letter, underscore (_), or dollar sign ($); subsequent characters can also be digits (0-9). Because JavaScript is case sensitive, letters include the characters "A" through "Z" (uppercase) and the characters "a" through "z" (lowercase).</p>

<p>You can use ISO 8859-1 or Unicode letters such as å and ü in identifiers. You can also use the Unicode escape sequences as characters in identifiers. Some examples of legal names are Number_hits, temp99, and _name. </p>
      </section>
      <section class="main-section" id="Declaring_variables">
      <header>Declaring variables</header>
      <p>You can declare a variable in three ways:</p>

      <p>With the keyword var. For example, </p>
      <code>var x = 42.</code>
      <p>This syntax can be used to declare both local and global variables.</p>

      <p>By simply assigning it a value. For example, </p>
      <code>let y = 13.</code>
      <p>This syntax can be used to declare a block scope local variable. See Variable scope below. </p>
      </section>
      <section class="main-section" id="Variable_scope">
      <header>Variable scope</header>
      <p>When you declare a variable outside of any function, it is called a global variable, because it is available to any other code in the current document. When you declare a variable within a function, it is called a local variable, because it is available only within that function. </p>
      <p>JavaScript before ECMAScript 2015 does not have block statement scope; rather, a variable declared within a block is local to the function (or global scope) that the block resides within. For example the following code will log 5, because the scope of x is the function (or global context) within which x is declared, not the block, which in this case is an if statement. </p>
      <code>if (true) { var x = 5; } console.log(x); // 5</code>
      <p>This behavior changes, when using the let declaration introduced in ECMAScript 2015. </p>
      <code>if (true) { let y = 5; } console.log(y); // ReferenceError: y is
            not defined</code>
      </section>
      <section class="main-section" id="Global_variables">
      <header>Global variables</header>
      <p>Global variables are in fact properties of the global object. In web pages the global object is window, so you can set and access global variables using the window.variable syntax. </p>
      <p>Consequently, you can access global variables declared in one window or frame from another window or frame by specifying the window or frame name. For example, if a variable called phoneNumber is declared in a document, you can refer to this variable from an iframe as parent.phoneNumber. </p>
      </section>
      <section class="main-section" id="Constants">
      <header>Constants</header>
      <p>You can create a read-only, named constant with the const keyword. The syntax of a constant identifier is the same as for a variable identifier: it must start with a letter, underscore or dollar sign and can contain alphabetic, numeric, or underscore characters. </p>
      <code>const PI = 3.14;</code>
      <p>A constant cannot change value through assignment or be re-declared while the script is running. It has to be initialized to a value. </p>
      <p>The scope rules for constants are the same as those for let block scope variables. If the const keyword is omitted, the identifier is assumed to represent a variable. </p>
      <p>You cannot declare a constant with the same name as a function or variable in the same scope. For example: </p>
      <code>// THIS WILL CAUSE AN ERROR function f() {}; const f = 5; // THIS
            WILL CAUSE AN ERROR ALSO function f() { const g = 5; var g;
            //statements }</code>
            <p>However, object attributes are not protected, so the following statement is executed without problems. </p>
            <code>const MY_OBJECT = {"key": "value"}; MY_OBJECT.key =
            "otherValue";</code>
      </section>
      <section class="main-section" id="Data_types">
      <header>Data types</header>
      <p>The latest ECMAScript standard defines seven data types:</p>
      <ul>
      <li>Six data types that are primitives:</li>
      <li>Boolean. true and false.</li>
      <li>null. A special keyword denoting a null value. Because JavaScript is case-sensitive, null is not the same as Null, NULL, or any other variant. </li>
      <li>undefined. A top-level property whose value is undefined. </li>
      <li>Number. 42 or 3.14159.</li>
      <li>String. "Howdy"</li>
      <li>Symbol (new in ECMAScript 2015). A data type whose instances are unique and immutable. </li>
      </ul>
      <p>Although these data types are a relatively small amount, they enable you to perform useful functions with your applications. Objects and functions are the other fundamental elements in the language. You can think of objects as named containers for values, and functions as procedures that your application can perform. </p>
      </section>
      <section class="main-section" id="if_else_statement">
      <header>if else statement</header>
      <p>Use the if statement to execute a statement if a logical condition is true. Use the optional else clause to execute a statement if the condition is false. An if statement looks as follows: </p>
      <code>if (condition) { statement_1; } else { statement_2; }</code>
      <p>condition can be any expression that evaluates to true or false. See Boolean for an explanation of what evaluates to true and false. If condition evaluates to true, statement_1 is executed; otherwise, statement_2 is executed. statement_1 and statement_2 can be any statement, including further nested if statements. </p>
      <p>You may also compound the statements using else if to have multiple conditions tested in sequence, as follows: </p>
      <code>if (condition_1) { statement_1; } else if (condition_2) {
            statement_2; } else if (condition_n) { statement_n; } else {
            statement_last; }</code>
            <p>In the case of multiple conditions only the first logical condition which evaluates to true will be executed. To execute multiple statements, group them within a block statement ({ ... }) . In general, it's good practice to always use block statements, especially when nesting if statements: </p>
            <code>if (condition) { statement_1_runs_if_condition_is_true;
            statement_2_runs_if_condition_is_true; } else {
            statement_3_runs_if_condition_is_false;
            statement_4_runs_if_condition_is_false; }</code>
            <p>It is advisable to not use simple assignments in a conditional expression, because the assignment can be confused with equality when glancing over the code. For example, do not use the following code: </p>
            <code>if (x = y) { /* statements here */ }</code>
            <p>If you need to use an assignment in a conditional expression, a common practice is to put additional parentheses around the assignment. For example: </p>
            <code>if ((x = y)) { /* statements here */ }</code>
      </main>

PLSS HELPPP!!

¡Hola!

No revise todo el codigo, pero note que te falta un guion en esta referencia.

Si corrigiendo ese detalle aun falla el codigo, le puedo dar una revision mas detallada.

Saludos.

muchas gracias por su ayuda! … (thank you very much for your help). but can u help me with this error too : Each .nav-link should have an href attribute that links to its corresponding .main-section (e.g. If you click on a .nav-link element that contains the text “Hello world”, the page navigates to a section element with that id). i can’t understand what did i do wrong …

      <code>// THIS WILL CAUSE AN ERROR function f() {}; const f = 5; // THIS
            WILL CAUSE AN ERROR ALSO function f() { const g = 5; var g;
            //statements }</code>
            <p>However, object attributes are not protected, so the following statement is executed without problems. </p>
            <code>const MY_OBJECT = {"key": "value"}; MY_OBJECT.key =
            "otherValue";</code>
      </section>
      <section class="main-section" id="Data_types">
      <header>Data types</header>
      <p>The latest ECMAScript standard defines seven data types:</p>
      <ul>
      <li>Six data types that are primitives:</li>
      <li>Boolean. true and false.</li>
      <li>null. A special keyword denoting a null value. Because JavaScript is case-sensitive, null is not the same as Null, NULL, or any other variant. </li>
      <li>undefined. A top-level property whose value is undefined. </li>
      <li>Number. 42 or 3.14159.</li>
      <li>String. "Howdy"</li>
      <li>Symbol (new in ECMAScript 2015). A data type whose instances are unique and immutable. </li>
      </ul>
      <p>Although these data types are a relatively small amount, they enable you to perform useful functions with your applications. Objects and functions are the other fundamental elements in the language. You can think of objects as named containers for values, and functions as procedures that your application can perform. </p>
      </section>
      <section class="main-section" id="if_else_statement">
      <header>if else statement</header>
      <p>Use the if statement to execute a statement if a logical condition is true. Use the optional else clause to execute a statement if the condition is false. An if statement looks as follows: </p>
      <code>if (condition) { statement_1; } else { statement_2; }</code>
      <p>condition can be any expression that evaluates to true or false. See Boolean for an explanation of what evaluates to true and false. If condition evaluates to true, statement_1 is executed; otherwise, statement_2 is executed. statement_1 and statement_2 can be any statement, including further nested if statements. </p>
      <p>You may also compound the statements using else if to have multiple conditions tested in sequence, as follows: </p>
      <code>if (condition_1) { statement_1; } else if (condition_2) {
            statement_2; } else if (condition_n) { statement_n; } else {
            statement_last; }</code>
            <p>In the case of multiple conditions only the first logical condition which evaluates to true will be executed. To execute multiple statements, group them within a block statement ({ ... }) . In general, it's good practice to always use block statements, especially when nesting if statements: </p>
            <code>if (condition) { statement_1_runs_if_condition_is_true;
            statement_2_runs_if_condition_is_true; } else {
            statement_3_runs_if_condition_is_false;
            statement_4_runs_if_condition_is_false; }</code>
            <p>It is advisable to not use simple assignments in a conditional expression, because the assignment can be confused with equality when glancing over the code. For example, do not use the following code: </p>
            <code>if (x = y) { /* statements here */ }</code>
            <p>If you need to use an assignment in a conditional expression, a common practice is to put additional parentheses around the assignment. For example: </p>
            <code>if ((x = y)) { /* statements here */ }</code>
      </main>
      </body>
      </html>

Do these links work?

1 Like

Yes the links works…

I am confused. Have you solved the issue? (You marked my last post as solution?)

ohh sorry sorry … my mistake i clicked on solution sorry

okay, can you look again at the post where I asked you if the 3 nav links are working?
they don’t seem to be working to me.
(did you actually try to click on the Reference link to see if it works for eg?)

¡Hola!

Esta referencia aun esta incorrecta, tienes un espacio antes de la ultima palabra.

Y las 3 ultimas referencias no llevan a ningun lugar, esto porque tu codigo no contiene esos capitulos, entonces si borras esos 3 enlaces, o agregas el contenido de esos 3 capitulos, la prueba en la que estas fallando deberia de pasar.

saludos.

HI … i can’t undrestand what are you trying to day here’s the new code …

Lo siento por la respuesta tardía (Sorry for the late reply)

¡Hola!

No se que decirte.

El codigo que envias esta vez es de otro proyecto, y por cierto es muy similar a este https://personal-portfolio.freecodecamp.rocks/

Entonces, si ocupas ayuda para corregir tu codigo, con mucho gusto lo puedo intentar, pero primero define bien el proyecto que pretendes elaborar.

saludos

Hola !! … sí, es el último proyecto … con el que estoy atascado … el problema de la navebar … Todo correcto excepto el de este error. Simplemente no puedo entender cuál es el problema . Error : Your #navbar element should always be at the top of the viewport.

Si lo que quieres es que la #navbar este siempre en la parte superior de la ventana grafica debes diseñarla con reglas CSS, en este caso ocupas el posicionamiento, el siguiente enlace explican como hacerlo CSS Layout - The position Property

Pero si estas construyendo los proyectos para obtener la certificacion de Diseño Web Responsivo deberias de construir un proyecto propio, algo como esto: https://codepen.io/nadiannis/full/VXXzWL
https://codepen.io/MAOKG/full/GrRRKO/
https://codepen.io/abdelkarim-khallouk/full/bLKbYw/

Y en este caso me parece que estas copiando el proyecto de ejemplo.

saludos

sí… porque el código que había creado también mostraba este error y no solo eso, sino que también se mostraban algunos errores… así que pensé en buscar este proyecto en youtube… para ver cómo lo han hecho eso . hecho . Pero la mayor parte del tutorial que vi… habían corregido este error… y parte del tutorial no lo revisaron… simplemente lo movieron… así que pensé en borrar este código… Hice un nuevo código. … pero aún así no funcionó … y sí … otro proyecto como proyecto de tributo, etc … tuve los mismos errores solo el NAVBAR es el error … así que busqué en Google pero fallé … había una solución pero esa era NO funciona conmigo… Si quieres, te puedo mostrar el código que hice ahora… Estaba a medio hacer, pero si quieres… Puedo compartirlo

De hecho la mejor forma de poder ayudarte es que compartas tu codigo, no importa que no este terminado, siempre que se pueda apreciar el problema que tienes.

Ya viendo el codigo se te puede ayudar de una forma mas personalizada.

saludos

bien . ¿Puedo compartirte el código más tarde? Estoy fuera

Hola… cuando me dijiste que compartiera mi código a medio hacer. No pude encontrarlo e hice uno nuevo, estaba medio completo… cuando hice clic para verificar mi código… el error que mostraba desapareció y se mostraba bien… así que gracias por decírmelo comparte MI código si no me lo hubieras dicho. … Habría creído que mi propio código está mal y siempre estará a medio hacer. GRACIAS DE NUEVO
