The example in this article describes the implementation method of dynamic creation of javascript elements. Share it with everyone for your reference. The specific analysis is as follows:
document.write can only be created dynamically during page loading
You can call the document's createElement method to create a DOM object with the specified tag, and then add the
by calling the element's appendChild method.
The newly created element is added under the corresponding element
For example:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Dom动态创建元素</title>
<script type="text/javascript">
function CreateButton() {
var div = document.getElementById("divMain");
var myButton = document.createElement("input");
myButton.type = "button";
myButton.value = "我是动态添加的";
//myButton.id="btn"; 注意:如果设置id的话要避免重复
div.appendChild(myButton); //添加到div上
}
</script>
</head>
<body>
<div id="divMain"></div>
<input type="button" value="添加元素" onclick="CreateButton()" />
</body>
</html>I hope this article will be helpful to everyone’s JavaScript programming design.
