The examples in this article describe the two creation methods of createElement in javascript. Share it with everyone for your reference. The specific implementation method is as follows: 

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
 <title>CreateElement的两种创建方式</title>
 <script type="text/javascript">
 function CreateButton1() {
  var btn = document.createElement("input");
  btn.type = "button";
  btn.value = "我是动态创建的1";
  btn.onclick = function () {
  alert(this.value);
  }
  document.body.appendChild(btn);
 }
 function CreateButton2() {
  var btn = document.createElement("<input type='button' value='我是动态创建的2' "+"onclick='OnClick2(this)' />");
  document.body.appendChild(btn);
 }
 function OnClick2(btn) {
  alert(btn.value);
 }
 function CreateLink() {
  var link = document.createElement("<a href='http://www.baidu.com'>百度</a>");
  //注意这里链接的文本“百度”是不会显示出来的，
  //必须设置innerText或innerHTML
  link.innerText = "百度";
  document.body.appendChild(link);
 }
 function CreateLabel() {
  var lbl = document.createElement("label");
  lbl.setAttribute("for", "userName");
  lbl.setAttribute("myAge", "12");
  //可以设置自定义标示
  lbl.innerText = "用户名:";
  document.body.appendChild(lbl);
 }
 </script>
</head>
<body>
 <input type="button" value="动态创建按钮1" onclick="CreateButton1()" />
 <input type="button" value="动态创建按钮2" onclick="CreateButton2()" />
 <input type="button" value="动态创建链接" onclick="CreateLink()" />
 <input type="button" value="动态创建Label" onclick="CreateLabel()" />
 <input type="text" id="userName" value="李莫" />
</body>
</html>
