Tags contain content operations
Use javascript operations:
Note: innerHTML is not a w3c standard technology , many browsers only support it
Use jquery operation:
- ##$().html(); // Get the information contained in the node
- $().html(information); //Set the content contained in the node
- $().text (); //Get the "text string information" content contained in the node
- $().text(information); //Set the content contained in the node (if there is an html tag, just The "><" symbol becomes a symbol entity)
<!DOCTYPE html>
<html>
<head>
<title>php.cn</title>
<meta charset="utf-8" />
<script src="http://libs.baidu.com/jquery/1.10.2/jquery.min.js"></script>
<script>
function f1(){
alert($('div').html());
alert($('div').text());
}
function f2(){
$('div').text("这里是php中文网");
}
</script>
</head>
<body>
<div>欢迎 <p>大家 <span>学习jQuery</span></p></div>
<input type="button" value="获取" onclick="f1()" />
<input type="button" value="设置" onclick="f2()" />
</body>
</html>
##The difference between html() and text() methods ：
##① Get content
The former can get html tags and ordinary string content
The latter only gets ordinary string content
② Set content
The former can set html tags and ordinary string content
The latter only sets ordinary string content. If there is tag tag content in the content, put the "< ;" ">" symbol is converted into a symbol entity<-----$lt; >----> Space------
The above two operations (get /Settings) If the operation content is pure string content, the effect will be the same.
