Using external javascript files in a .js file

Question

I would like to use an external javascript file in another javascript file. For example, I could store all my global variables in a globals.js file and then call then from t

Answer 1

You can also do something like this:

$(document).ready(function(){
    $('body').append($('<script src="/path/to/script/foo.min.js"></script>'));
});

Just use that line before you need to reference something in the included js file.

Answer 2

Javascript doesn't have any implicit "include this other file" mechanisms, like css's @include. You just have to list your globals file before the logic file in the tags:

 <script type="text/javascript" src="globals.js" />
 <script type="text/javascript" src="logic.js" />

If guaranteeing that the globals are available before anything in the logic file fires up, you can do a slow polling loop to see if some particular variable is available before calling an init() or whatever function.

Answer 3

function loadExternalJS(TARGET_URL){
var xhr = window.ActiveXObject ? new ActiveXObject("Microsoft.XMLHTTP") : new XMLHttpRequest();
xhr.open('GET', TARGET_URL, false);
xhr.send(null);
var code = xhr.responseText;
var dScript = document.createElement('script');
try {
dScript.appendChild( document.createTextNode(parsed) );
document.body.appendChild(dScript);
} catch(e) {
dScript.text = parsed;
document.getElementsByTagName('head')[0].appendChild(dScript);
}
xhr = null;

Answer 4

Just make sure both files are referenced in your index.html.

Answer 5

document.write('<script type="text/javascript" src="globals.js"></script>');

Edit: Actually, this probably won't work for your purposes, as global.js variables won't be accessible until logic.js completes. You may be able to wrap logic.js in a function that is called after global.js loads. Otherwise I don't think there is a way to do what you're asking.
