jQuery - AJAX load() Method
jQuery load() Method
The jQuery load() method is a simple, but powerful AJAX method.
The load() method loads data from a
server and puts the returned data into the selected element.
Syntax:
$(selector).load(URL,data,callback);
The required URL parameter specifies the URL you wish to load.
The optional data parameter specifies a set of querystring key/value pairs to send along with
the request.
The optional callback parameter is the name of a function to be executed
after the load() method is completed.
Here is the content of our example file: "demo_test.txt":
<h2>jQuery and AJAX is FUN!!!</h2>
<p id="p1">This is some text in a paragraph.</p>
The following example loads the content of the file "demo_test.txt" into a
specific <div> element:
Example
$("#div1").load("demo_test.txt");

It is also possible to add a jQuery selector to the URL parameter.
The following example loads the content of the element with id="p1", inside
the file "demo_test.txt", into a specific <div> element:
Example
$("#div1").load("demo_test.txt #p1");

The optional callback parameter specifies a callback function to run when the
load() method is completed. The callback function can have different parameters:
responseTxt - contains the resulting content if the call succeeds
statusTxt - contains the status of the call
xhr - contains the XMLHttpRequest object
The following example displays an alert box after the load() method
completes. If the load() method has succeeded, it displays "External content
loaded successfully!", and if it fails it displays an error message:
Example
$("button").click(function(){
$("#div1").load("demo_test.txt", function(responseTxt, statusTxt, xhr){
if(statusTxt == "success")
alert("External content loaded successfully!");
if(statusTxt == "error")
alert("Error: " + xhr.status + ": " + xhr.statusText);
});
});
