Remove <script> tags using jQuery

Question

I want to remove this Google Analytics block, using jQuery.

<script type="text/javascript">
    var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
    document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
    try {
        //var pageTracker = _gat._getTracker("xxx");
        pageTracker._trackPageview();
    } catch(err) {}
</script>

THE REASON

Because I am creating a bespoke screen reader convertor for jQuery based on a client specification. It's the Google Analytics that is bugging me.

THE PROBLEM

It works with .remove() until you navigate away, then press back. Google Analytics hangs.

Answer 1

Try this:

var replacementDoneIn = $(document.body).text(); //remove Google Analytics document.write line
        var regExMatch = /document\.write\(unescape/g;
        var replaceWith = "//document.write";
        var resultSet = replacementDoneIn.replace(regExMatch, replaceWith);
        $("body").html(resultSet);

Hope that helps!

You can also hook document.write and check if its google anlytics code before stopping it like this:

<script>
// Must run before google analytics though
old_document_write = document.write;
document.write = function(str)
{
     if(/* determine if the str is google analyic code */)
         return false; // dont write it
     else
        old_document_write(str);
}
</script>
