</style>
<script type="text/javascript">

</script>
<body>
//此处为ul动态添加li元素
<ul id="J_List">
</ul>
</body>
</html>js dynamically add Li Element code (Method 1)
var userName="Tom";
var userEamil="12345678@qq.com";
var userPhone="12345678910";
//方法1：用innerHTML
document.getElementById("J_List").innerHTML+="<li class=\"newLi\"><span>"+_userName+"<\/span><span>"+userEamil+"<\/span><span>"+userPhone+"<\/span><span><input type=\"button\" value=\"删除\" onclick=\"this.parentNode.parentNode.parentNode.removeChild
(this.parentNode.parentNode)\" \/><\/span><\/li>";##js dynamically add Li element code (Method 2)
//方法2：用createElement创建li元素，再通过setAttribute设置元素属性，最后通过appendChild()方法添加在父元素的最后一个子节点上。
//创建li标签，包含显示姓名，邮箱，电话号码及删除按钮
function addLi(useName,useEamil,usePhone){
var li_1=document.createElement("li");
li_1.setAttribute("class","newLi");
addSpan(li_1,userName);
addSpan(li_1,userEamil);
addSpan(li_1,userPhone);
addDelBtn(li_1);
document.getElementById("J_List").appendChild(li_1);
}
//为姓名或邮箱等添加span标签，好设置样式
function addSpan(li,text){
var span_1=document.createElement("span");
span_1.innerHTML=text;
li.appendChild(span_1);
}
//添加删除按钮及设置删除按钮的样式及添加点击事件
function addDelBtn(li){
var span_1=document.createElement("span");
var btn=document.createElement("button");
btn.setAttribute("type","button");
btn.setAttribute("class","delBtn");
btn.setAttribute("onclick","delBtnData(this)");
btn.innerHTML="删除";
span_1.appendChild(btn);
li.appendChild(span_1);
}
//为删除按钮添加删除节点功能
function delBtnData(obj){
var ul=document.getElementById("J_List");
var oLi=obj.parentNode.parentNode;
//obj.parentNode指删除按钮的span层
//obj.parentNode.parentNode为li层
ul.removeChild(oLi);
}Knowledge points: innerHTML (note the double quotes" or \ need to use / transfer meaning).
Knowledge points: createElement creates elements, setAttribute sets element attributes, innerHTML sets element values, appendChild adds elements, and parentNode gets the parent node (parentNode is W3C Standard, parentElement is only available in IE.), removeChild deletes the child node.
