不懂的+我Q：459348730
用js找到那个标签位置，先删除你要改的标签，然后在容器div下面新增你要改成的标签内容，下面使用jq演示一下，首先要引入jq文件才能进行一下 *** 作。<div id="div"><input type="text" id="inp" /></div>
<div id="data">请输入要修改成的标签及内容：<input type="text" id="content" /></div>
<a href="#" onclick="alter()return false">修改标签</a>
<script>
function alter(){
var data = $("#content").val()
$("div").empty().append(data)
}
</script>
