jQuery The functions of HTML() and Load() are very similar. They can both change the content of HTML. Of course, there are some obvious differences.

jQuery HTML Operation details:

jQuery contains many powerful functions for changing and manipulating HTML.

The HTML() method changes the HTML content

Syntax

$(selector).html(content)

Copy after login

Similar to the html() function, it changes the content of the matched HTML element (innerHTML) .

Example

$("p").html("html content");

jQuery Load Operation details:

Definition and usage

The load() method loads the remote HTML file code and inserts it into the DOM.

The difference between Jquery's Load() method and html() is that after loading the remote HTML file, it can also execute the Javascrpt script in it.

The GET method is used by default - automatically converted to POST method when passing additional parameters.

In jQuery 1.2, you can specify a selector to filter the loaded HTML document, and only the filtered HTML code will be inserted into the DOM. The syntax is like "url #some > selector".

Please see the example below.

Syntax

load(url,[data],[callback])

Copy after login

##dataThe key/ sent to the server. value data. In jQuery 1.3, a ##callback. Example 1

Parameters	Description
url	The URL of the HTML page to be loaded
	string can also be accepted.
Callback executed when loading is successful. Function

Similar to the above example, but sends additional parameters as a POST and displays the message on success:

$("#feeds").load("feeds.php", {limit: 25}, function(){
  alert("The last 25 entries in the feed have been loaded");
});

Copy after login

Example 2

Load article sidebar

Navigation

section to an unordered list:

HTML code:

<b>jQuery Links:</b>
<ul id="links"></ul>

Copy after login

jQuery code :

$("#links").load("/Main_Page #p-Getting-Started li");

Copy after login
