Async JS if statements

[revenstar2]

I want to create a line of code, so that if there is no universities/result with the name it search, it runs a code setting an alert

Any idea? I can’t make it work for some reason

[juangpereira]

if( uni.name == undefined ){
       alert( ' Alert ' ); 
}

Debería funcionar, no?

[revenstar2]

No, I guess it must be the way the API works as it returns an empty array when it doesn’t detect

[juangpereira]

That value is not equivalent to false? Or you could check the length property, if it returns 0 it is because it is an empty array

What about:

if (array.length === 0) {
  alert('Alert'); 
}

Thank you for this, but it doesn’t work, I feel like the API doesn’t really spit back anything now that I rechecked, it’s weird but it’s how it is funnily enough

if array is empty the loop doesn’t run, Where are you putting the code for alert?

[revenstar2]

So there’s a loop I created that creates and attach elements to the div to show the stuff I get from API, so I add a logic that goes

‘If the search get backs nothing, please alert()’

But I can’t really implement it

This is what I get when I search for something that don’t exist within the API

[ILM]

and can you show the code that you have written for that?

[revenstar2]

Sorry I actually got the code running already, when you talked about the loop I realized, I misplaced the position of the code within the loop, and so when I use Kevin Smith’s code, it’s right, but it’s in the wrong place.

Thank you again for the help
