Jquery瀑布流 如何在元素display属性更改后 把所有left为0的div的class值修改掉

原html代码
<style>

#feed_div { position: relative; }
.item { display: none; }
</style>
<div id="feed_div">
<div class="item">...</div>
<div class="item">...</div>
<div class="item">...</div>
...
<div class="item">...</div>
</div>
导入wookmark
<script type="text/javascript" src="./js/jquery.min.js"></script>
<script type="text/javascript" src="./js/jquery.wookmark.min.js"></script>
<script>
jQuery.noConflict();
jQuery('#feed_div .item').wookmark({
container : jQuery("#feed_div"), align:'left',itemWidth:530,autoResize:false,offset:90,verticalOffset:15
});
</script>
使用Jquery wookmark进行瀑布流排版后

<div id="feed_div" style="height: 2051px;">
<div class="item" style="display: block; position: absolute; top: 0px; left: 0px;">...</div>
<div class="item" style="display: block; position: absolute; top: 0px; left: 620px;">...</div>
<div class="item" style="display: block; position: absolute; top: 183px; left: 0px;">...</div>
<div class="item" style="display: block; position: absolute; top: 437px; left: 620px;">...</div>
....
<div class="item" style="display: block; position: absolute; top: 807px; left: 0px;">...</div>
</div>

Answer 1

var divs = $('div');
divs.each(function(){
    var divObj = $(this);
    if(divObj.css('left')==='0px'){
        divObj.addClass("item left");
    }
});
