页面的head部分，需引入页面元素的样式文件，代码如下：

<link type="text/css" href="css/style.css" rel="stylesheet">

页面的body部分，分别设置好标签显示的容器和创建标签输入框和触发按钮，代码如下：

<div class="tagBox">
    <div class="tagTiltle">
        <h3>我的技能</h3>
        <p>可添加10个技能标签</p>
    </div>
    <div class="tagCon clearfix" id="tagcon">

    </div>
    <div class="addBox clearfix" id="addBox">
        <input class="" type="text"/>
        <button>增加</button>
    </div>
</div>

页面的底部，需设置好标签创建的事件响应，代码如下：

var tagcon = $("tagcon");
var addBox = $("addBox");
var addBtn = addBox.children[1];
var intxt = addBox.children[0];
var divs = tagcon.children;

function $(id){ return document.getElementById(id) }//$获取元素函数封装
function crele(ele){ return document.createElement(ele); } //创建元素
function adson(father,son1,son2,son3,clas1,clas2,clas3,clas4,con1,con2){
    father.appendChild(son1);
    father.appendChild(son2);
    father.appendChild(son3);
    father.className = clas1;
    son1.className = clas2;
    son2.className = clas3;
    son3.className = clas4;
    son1.innerHTML = con1;
    son3.innerHTML = con2;
}
//输入框聚焦和失焦的效果
intxt.onfocus = function(){
    intxt.style.backgroundColor = "#fff";
}
intxt.onblur = function () {
    intxt.style.backgroundColor = "#e3e3e3";
}
//点击add按钮添加标签
addBtn.onclick = function () {
    if(intxt.value != ""){
        var newdiv = crele("div");
        var newem = crele("em");
        var newspan = crele("span");
        var newa = crele("a");
        if(divs.length == 0){//最新添加的标签在最前边
            tagcon.appendChild(newdiv);
        }else{
            tagcon.insertBefore(newdiv,divs[0])
        }
        adson(newdiv,newem,newspan,newa,"tag","tagtxt","move","closetag",intxt.value,"×")
        intxt.value = "";
    }else{
        alert("你还没有输入呢！");
    }
    //console.log(links.length);
    newa.onclick = function () {
        this.parentNode.style.display = "none";
    }
}
