Question

i am having a bit of a problem here and i don’t even know if it is possible at all, here’s my dilema:

I have this script code:

<script id='script1' src='http://link.to.js'></script>

While using firebug, i can clearly see that the script has bee loaded between those tags, like this

<script id='script1' src='http://link.to.js'>
  function something(){
    alert('hi');}
</script>

What i want to do is, by means of another script, get the content between those tags, something like

var x = document.getElementById('script1').innerHtml;
document.getElementById('somedividhere').innerHtml = x;

That works perfectly WHEN the code is already part of the html, not when its loaded from src.

I have been looking for this for hours and i have not found any hint, hope someone can help me on this.

I think Firebug only shows you that for convenience sake. If you want to get the code from the script, you’ll have to use AJAX.

You could do something like this:

function ajaxFunction(){
    var ajaxRequest;  // The variable that makes Ajax possible!

    try{
        // Opera 8.0+, Firefox, Safari
        ajaxRequest = new XMLHttpRequest();
    } catch (e){
        // Internet Explorer Browsers
        try{
            ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
        } catch (e) {
            try{
                ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
            } catch (e){
                // Something went wrong
                alert("Your browser broke!");
                return false;
            }
        }
    }
    // Create a function that will receive data sent from the server
    ajaxRequest.onreadystatechange = function(){
        if(ajaxRequest.readyState == 4){
            var scriptcontent = ajaxRequest.responseText;
            //Do something with the content
        }
    }
    ajaxRequest.open("GET", document.getElementById('script1').src, true);
    ajaxRequest.send(null);
}

Just a few notes:

1. This will only work for scripts
   located on your site due to the
   same origin
   policy.
2. I took the ajax code from this
   site
   and modified it.
3. This would be a lot
   easier with
   jQuery
