Example of html () method usage in jQuery, jquery instance
This document describes the use of the html () method in jQuery. Share it with you for your reference. The specific analysis is as follows:
This method can set and obtain the HTML content of the matching element. The original content will be replaced by the newly set content.
Note:
HTML content can contain HTML tags and be rendered by browsers.
The text content first converts the pre-defined HTML characters in the content into html character entities, so that HTML tags will not be rendered.
Syntax structure 1:
Copy codeCode: Optional (selector).html ()
In this case, when the method does not contain parameters, the html content of the First Matching Element is obtained.
This method has no parameter usage similar to the text () method, but there is a big difference:
The. html () method gets the content of the First Matching Element, while the text () method gets the content of all matching elements.
The 2.html () method obtains the html content, while the text () method obtains the text content.
Instance code:
Copy codeThe Code is as follows:
<! DOCTYPE html>
<Html>
<Head>
<Meta charset = "UTF-8">
<Meta name = "author" content = "http://www.bkjia.com/"/>
<Title> helping customers </title>
<Style type = "text/css">
Div
{
Height: 150px;
Width: 150px;
Background-color: green;
Margin-top: 10px;
}
</Style>
<Script type = "text/javascript" src = "mytest/jQuery/jquery-1.8.3.js"> </script>
<Script type = "text/javascript">
$ (Document). ready (function (){
$ ("Button"). click (function (){
Alert ($ ("div" pai.html ());
})
})
</Script>
</Head>
<Body>
<Div>
<Ul>
<Li> <span> welcome </span> </li>
</Ul>
</Div>
<Button> click to view results </button>
</Body>
</Html>
The above code returns the content in the div element.
Syntax structure 2:
Copy codeThe Code is as follows: Response (selector).html (content)
When parameters are included, the html content is set for all matching elements.
This method is similar to the text () method with parameters, but there is a big difference:
The html () method sets the html content, while the text () method sets the text content.
Instance code:
The following code sets the html content in the div to "<B> I'm resetting the content </B> ".
Copy codeThe Code is as follows:
<! DOCTYPE html>
<Html>
<Head>
<Meta charset = "UTF-8">
<Meta name = "author" content = "http://www.bkjia.com/"/>
<Title> helping customers </title>
<Style type = "text/css">
Div
{
Height: 150px;
Width: 150px;
Background-color: green;
Margin-top: 10px;
}
</Style>
<Script type = "text/javascript" src = "mytest/jQuery/jquery-1.8.3.js"> </script>
<Script type = "text/javascript">
$ (Document). ready (function (){
$ ("Button"). click (function (){
$ ("Div" ).html ("<B> I reset the content </B> ");
})
})
</Script>
</Head>
<Body>
<Div> original content </div>
<Button> click to view results </button>
</Body>
</Html>
Example 2:
Copy codeThe Code is as follows:
<! DOCTYPE html>
<Html>
<Head>
<Meta charset = "UTF-8">
<Meta name = "author" content = "http://www.bkjia.com/"/>
<Title> helping customers </title>
<Style type = "text/css">
Div
{
Height: 150px;
Width: 150px;
Background-color: green;
Margin-top: 10px;
}
</Style>
<Script type = "text/javascript" src = "mytest/jQuery/jquery-1.8.3.js"> </script>
<Script type = "text/javascript">
$ (Document). ready (function (){
$ ("Button"). click (function (){
$ (". Html" ).html ("<B> learn </B> ");
$ (". Text"). text ("<B> learn </B> ");
})
})
</Script>
</Head>
<Body>
<Div class = "html"> </div>
<Div class = "text"> </div>
<Button> click to view results </button>
</Body>
</Html>
