下面小编就为大家带来一篇jquery操作ul的一些操作笔记整理(干货)。小编觉得挺不错的，现在就分享给大家，也给大家做个参考。一起跟随小编过来看看吧
1、html标记
<ul id="attachtext"> <li data-text="111"><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >查看附件</a> <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >删除</a></li> <li data-text="222"><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >查看附件</a> <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >删除</a></li> <li data-text="333"><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >查看附件</a> <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >删除</a></li> </ul>
js
1、获取 li属性 data-text的值用 ，隔开
function getvalues() { var values = ""; var obj = $("#attachtext li"); if(obj.length>0) { var len = $(obj).length-1; $.each(obj, function (index, value) { //表示为最后一个元素 if (index == len) { values += $(value).attr("data-text"); } else { values += $(value).attr("data-text") + ","; } }) } console.log(values); }
输出结果;111,222,333
2、编辑的时候初始化ul的li项
function loadattach() { $("#attachtext").html("");//先清空 var data="111,222,333"; var arr = data.split(','); $.each(arr, function (index, value) { $("#attachtext").prepend("<li data-value=\"" + $.parsejson(data).data + "\"><a>查看附件</a> <a>删除</a></li>"); }); }
以上就是jquery操作ul技巧总结的详细内容。
