jQuery - AJAX get() and post() Methods
The jQuery get() and post() methods are used to request data from the server with an HTTP GET or POST request.
HTTP Request: GET vs. POST
Two commonly used methods for a request-response between a client and server are: GET and POST.
- GET - Requests data from a specified resource
- POST - Submits data to be processed to a specified resource
GET is basically used for just getting (retrieving) some data from the server. Note: The GET method may return cached data.
POST can also be used to get some data from the server. However, the POST method NEVER caches data, and is often used to send data along with the request.
jQuery $.get() Method
The $.get()
method requests data from the server with an HTTP GET request.
The required URL parameter specifies the URL you wish to request.
The optional callback parameter is the name of a function to be executed if the request succeeds.
The following example uses the $.get() method to retrieve data from a file on the server:
$("button").click(function(){ $.get("demo_test.asp", function(data, status){ alert("Data: " + data + "\nStatus: " + status); }); });
