按class排序div元素（jQuery/Javascript）

Question

我想用class排序#list中的div元素（cat1，cat2，cat3等...）。

<section id="list" class="pix_wall pix_load_content isotope" style="position: relative; overflow: hidden; height: 570px; opacity: 1;"> 
<div class="cat8 entry post-id-34 isotope-item" data-sort="8" style="position: absolute; left: 0px; top: 0px;"> 
</div> 
<div class="cat2 entry post-id-124 isotope-item" data-sort="2" style="position: absolute; left: 380px; top: 0px;"> 
</div> 
<div class="cat7 entry post-id-79 isotope-item" data-sort="7" style="position: absolute; left: 760px; top: 0px;"> 
</div> 
<div class="cat5 entry post-id-87 isotope-item" data-sort="5" style="position: absolute; left: 1140px; top: 0px;"> 
</div> 
<div class="cat3 entry post-id-95 isotope-item" data-sort="3" style="position: absolute; left: 1520px; top: 0px;"> 
</div> 
<div class="cat1 entry post-id-99 isotope-item" data-sort="1" style="position: absolute; left: 0px; top: 285px;"> 
</div> 
</section> 

任何人都可以幫助我嗎？

var sorted_entries = $('.entry').sort(function (a, b) { 
    var _a = /cat(\d+)/.exec(a.className)[1]; 
    var _b = /cat(\d+)/.exec(b.className)[1]; 

    if (_a < _b) { 
     return -1; 
    } else if (_a > _b) { 
     return 1; 
    } else { 
     return 0; 
    } 
}); 

$('section').html(sorted_entries);
