jquery操作ul的一些操作笔记整理(干货)

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>");     
   });
  }
