I have three "a" class's that change color when selected, but I need one to be default on load of page

I'm working on this project and I need to add this functionality where we have three products listed.

they started out as div's but changed them to ahref class's to link the entire area.

The box has to change color when hovered - which I have done. The box needs to change to another color when clicked on - which I have also done.

The one thing I can't figure out is how to make the 2nd box default as selected but then have the color turn off when another one is selected

This is the javascript I have for the page.

var highlightLink = function () {
    var active = null, colour = '#f6efa2';
    if (this.attachEvent) this.attachEvent('onunload', function () {
        active = null;
    });
    return function (element) {
        if ((active != element) && element.style) {
            if (active) active.style.backgroundColor = '';
            element.style.backgroundColor = colour;
            active = element;
        }
    };

}();

here is one of the boxs

<a class="productBox1" href="#" border="0" onclick="highlightLink(this);">

I'm thinking I need an onload function in the body tag but I don't know what code is needed and I also need it to becom开发者_如何转开发e unselected when another box is selected.

Any help would be greatly appreciated.


If every link has it's own class anyway, use it as ID instead:

<a id="productBox1" href="#" border="0" onclick="highlightLink(this);">

Use classes for common properties. For identifying single elements, use IDs.

Then you can add this to the bottom of your page (above the closing <body> tag):

<script type="text/javascript">
    highlightLink(document.getElementById('productBox1'));
</script>

or set

window.onload = function() {
    highlightLink(document.getElementById('productBox1'));
}

in the <head>.


Sounds like you're making this more complicated than it really is. Try this (I'm assuming all your a tags have class productBox1):

$('.productBox1').click(function() {
    $('.highlighted').removeClass('highlighted');
    $(this).addClass('highlighted');
});

Then have a css class called highlighted which has background-color: #f6efa2. You need jQuery in order to make this work properly.
