Another API related Question 🤦‍♂️

JavaScript

Hi, so I want to generate a page that has three random Chuck Norris jokes, I have used the code as per below, however I get the same joke on all three, is there a way to get three random ones and not the same ones and how would I write it to html?

JavaScript:

fetch("http://api.icndb.com/jokes/random/3")
  .then(res => res.json())
  .then(function(result) {
    jokes = result.value[1].joke;
    jokes2 = result.value[1].joke;
    jokes3 = result.value[1].joke;
    console.log(jokes + " " + jokes2 + " " + jokes3);
  }),
  error => {
    console.log(error + "");
  };

I created the below on my HTML page;

<div id="jokes" class="container mt-5">
        <p id="joke1">Joke 1</p>
        <p id="joke2">Joke 2</p>
        <p id="joke3">Joke 3</p>
    </div>

Hello!

Your code is almost right:

fetch("http://api.icndb.com/jokes/random/3")
  .then(res => res.json())
  .then(function(result) {
    // You're using the same result for every jokes* variable: result.value[1].
    // The fix:
    jokes = result.value[0].joke;
    jokes2 = result.value[1].joke;
    jokes3 = result.value[2].joke;
    console.log(jokes + " " + jokes2 + " " + jokes3);
  }),
  error => {
    console.log(error + "");
  };

The previous code should work.

Now I feel I can kick myself lol. I see what you are saying by calling the same joke three times, I didn’t call a different one, just the same line three times.

So now to add it to my HTML document and have it populate automatically, I just add this:

document.getElementByID('joke1').innerHTML = jokes;

Worst things happens :stuck_out_tongue:.

Imagine having thousands of lines of code and, for some unexplained reason, the project doesn’t work. After hours You find that a semicolon was missing :sob:.

This happens to (almost?) everyone, that’s why there exists QA (Quality Assurance).

If I do this though I get the error as per below;
‘(node:1652) UnhandledPromiseRejectionWarning: ReferenceError: document is not defined’

I tried this way as well, but get the same error,

fetch("http://api.icndb.com/jokes/random/3")
  .then(res => res.json())
  .then(function(result) {
    jokes = result.value[0].joke;
    jokes2 = result.value[1].joke;
    jokes3 = result.value[2].joke;
    console.log(jokes + " " + jokes2 + " " + jokes3);
    document.getElementById("joke1").innerHTML = jokes;
    document.getElementById("joke2").innerHTML = jokes2;
    document.getElementById("joke3").innerHTML = jokes3;
  }),
  error => {
    console.log(error + "");
  };

No, still in VS Code and terminal. I am using live preview to view the html page in the browser though.

Can I post the entire page here? Its a normal html file, with headings, body and script tags.

Sure no problem sir, it looks like this:

require("isomorphic-fetch");

fetch("http://api.icndb.com/jokes/random/3")
  .then(res => res.json())
  .then(function(result) {
    jokes = result.value[0].joke;
    jokes2 = result.value[1].joke;
    jokes3 = result.value[2].joke;
    console.log(jokes + " " + jokes2 + " " + jokes3);
    document.getElementById("joke1").innerHTML = jokes;
    document.getElementById("joke2").innerHTML = jokes2;
    document.getElementById("joke3").innerHTML = jokes3;
  }),
  error => {
    console.log(error + "");
  };
16

Would it work by running the code in an IIFE function?

18

May I ask as to why though? I was under the imperession that it is required on the page for the fetch() function?

20

Ah okay, so when this is server side I would use this right?

22

Okay, well thank you sirs, much appreciate the assistance and help in understanding.
