Question

I am trying to pass a has such as http://mysite.com/#32132 via JS to a custom function.

Here’s the function:

var downloadVideo = function(passed){
  console.log(passed);
}

And here’s how I’m getting and passing the hash from the URL:

if(window.location.hash){
    var hash = window.location.hash;
    hash = hash.substring(1, hash.length); // Remove the # from the hash
    setTimeout('downloadVideo('+hash+')', 3000)
}

After 3 seconds, I just get an error in the console:

Uncaught ReferenceError: 32132 is not defined

I’ve tried different ways of calling downloadVideo. With quotes, without quotes, without the plus signs. Nothing seems to work. If I console.log the hash var immediately before the setTimeout it displays it correctly.

You need to represent it as a string if there’s anything more than just numeric characters…

     // ------------------v--------v
setTimeout('downloadVideo("'+hash+'")', 3000);

But better to pass a function that closes over hash…

setTimeout(function() { downloadVideo(hash) }, 3000);
