jQuery & PHP : How can I reorder a list items by their class?


Firstly, sorry for my bad english, I hope I'll explain well my problem...

So, I'm trying to learn developping and actually I have this code :

<ul>
    <li class="odd ajax_block_product {if $smarty.foreach.myhomeFeaturedProducts.first}first_item{elseif $smarty.foreach.myhomeFeaturedProducts.last}last_item{else}item{/if} {if $smarty.foreach.myhomeFeaturedProducts.iteration%$nbItemsPerLine == 0}last_item_of_line{elseif $smarty.foreach.myhomeFeaturedProducts.iteration%$nbItemsPerLine == 1} {/if} {if $smarty.foreach.myhomeFeaturedProducts.iteration > ($smarty.foreach.myhomeFeaturedProducts.total - $totModulo)}last_line{/if}">...</li>    
    <li class="even ajax_block_category {if $smarty.foreach.myhomeFeaturedCategories.first}first_item{elseif $smarty.foreach.myhomeFeaturedCategories.last}last_item{else}item{/if}">...</li>
</ul>

The UL populates automaticly with smarty, so at the end my HTML is like this :

<ul>
    <li class="odd">1</li>     
    <li class="odd">2</li>
    <li class="odd">3</li>     
    <li class="odd">4</li>

    <li class="even">5</li>     
    <li class="even">6</li>
    <li class="even">7</li>     
    <li class="even">8</li>
</ul>

My problem is that I want to alternate EVEN and ODD classes with jQuery or PHP, but I didn't find how. I would like to make this :

     <ul>
        <li class="odd">1</li>     
        <li class="even">5</li>
        <li class="odd">2</li>     
        <li class="even">6</li>

        <li class="odd">3</li>     
        <li class="even">7</li>
        <li class="odd">4</li>     
        <li class="even">8</li>
    </ul>

Can somebody tell me how I need to do this please?

Thank you!


Solution

  • I find how to do this. Thank you all for helping me ! Here's the code for someone in my situation :

    $(function () {
        var $oddArray = new Array();
        var $evenArray = new Array();
        $('ul#shuffle li').each(function () {
            if ($(this).hasClass('product')) {
                $oddArray.push($(this).html());
            } else {
                $evenArray.push($(this).html());
            }
        });
        var newLi = new Array();
        var index;
        var oddIndex = 0;
        var evenIndex = 0;
        for (index = 0; index < ($oddArray.length + $evenArray.length); index++) {
            if (index % 2 == 0) {
                console.log("ODD");
                if ($oddArray[oddIndex] != undefined)
                    newLi += '<li>' + $oddArray[oddIndex] + '</li>';
                oddIndex++;
            } else {
                console.log("EVEN");
                if ($evenArray[evenIndex] != undefined)
                    newLi += '<li>' + $evenArray[evenIndex] + '</li>';
                evenIndex++;
            }
        }
        delete $oddArray;
        delete $evenArray;
        $('ul#shuffle').html(newLi);
    });
