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>");
});
}
