Run a Script to Disable a Script

Question

I need to run a script that will disable a another script on the page. How do I do this?

(Internet Explorer Issues is why I am having to do this.) I am using jQuery 1.8.

Please provide examples.

you can remove the script tag of the script you dont want to run by javascript — Mayank K. Swami

What have you tried so far? What are the Internet Explorer issues you are encountering? Are these scripts all on a page you have created yourself? — Richard Ev

@RichardEv - Nothing because I do not know where to start and JS is not my strong suit. I attempted to use conditional comments for my issue but those are not working correctly. — L84

If you show us the conditional comments approach you have tried, it will tell us a little more about the problem you are having. This will hopefully help us help you. — Richard Ev

@Lynda I think you might be complicating things too much. I answered your other question. I believe that's what you need to fix IE. Try to work with that, you don't need multiple scripts if you do it that way. Like I showed you can just use if (isIE8) within your code when you need it. — elclanrs

Using jQuery you can test for IE and then load the script if it returns true.

jQuery.browser might be moved to a plugin later, if it breaks when you update your library start looking into it first.

Keep in mind that it is usually not advisable to test for a specific browser, better to test for features the browser can work with. Sometimes you don't have a choice:

if(jQuery.browser.msie)
{
    $.getScript("lynda-ie.js");
}

If you need a script for a specific version if IE you can also test for its version :

if(jQuery.browser.msie)
{
    switch (parseInt(jQuery.browser.version,10))
    {
        case 6 :
            $.getScript("lynda-ie-6.js");
        break;
        case 7 :
            $.getScript("lynda-ie-7.js");
        break;
        case 8 : case 9 : default :
            $.getScript("lynda-ie.js");
        break;
}

It is, but it still works with jQuery 1.8. That's why I mentioned the library update issue.

Added a test for specific versions if you need to.

Why don't you use a flag ?

If this flag is "1" ( for example) the code will run

otherwise , it won't.

Can you provide an example? JS is not my strong suit.

A "nicer" way to conditionally attach scripts depending on whether a browser is IE or not is to use "conditional comments". These are available in IE5+ but are compatible with all browsers because of how they are designed. They allow you to set certain parts of your HTML as being intended for for IE only, or for all non-IE browsers, or all browsers (IE and non-IE).

Example:

<!--[if IE 8]>
<script src="internet-explorer.js"></script>
<![endif]-->

<![if !IE]>
<script src="not-internet-explorer.js"></script>
<![endif]>

<script src="all-browsers.js"></script>

That is what I originally attempted but for some reason it was not working correctly.
