jQuery tag contains content actions

Tags contain content operations

Use javascript operations:

  • dvnode.innerHTML Get the information contained in the div

  • dvnode.innerHTML = XXX; Set the content contained in the div

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("這里是php中文網(wǎng)");
            } 
        </script>
    </head>
    <body>
        <div>歡迎 <p>大家 <span>學(xué)習(xí)jQuery</span></p></div>

        <input type="button" value="獲取" onclick="f1()" />
        <input type="button" value="設(shè)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.
