Javascript rollover image vallidation issue

Apr 30, 2013 5:24 AM

Tags: #image #javascript #cs6



I am trying to add rollover images using CS6 however the code it places on my page won't vallidate and gives a heap of errors.


Can someone advise me how to attach the code to a seperate sheet so that my index page vallidates? or is there a way to hide the script so that the vallidation can't see it?

    I am not sure what 'flash' and 'photoshop' have in common with rollover images.


    May I suggest that you use jQuery to solve your problem.


    To do this, you need to link the library to your document as in

    <script src="//" ></script>

    The markup will look like

    <img src='/folder/image1.jpg' id='imageid'/>

    and the JS like


    $('#imageid').hover(function() {
    (this).attr('src', '/folder/image2.jpg');
    }, function() {
    (this).attr('src', '/folder/image1.jpg');

    DW's javascript will do that from time to time.


    I typically move it to an external .js file when that happens so I can get the rest of the page to validate.


    EDIT: To move it out, copy and paste everything from between the <script> tags in the <head> into a new .js file. Then link to that file from the <head> like so...


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


    Do not include the <script> tags in the actual .js file
