This article focuses on "what are the commonly used ajax methods in jquery". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn what are the ajax methods commonly used in jquery.

Jquery provides commonly used ajax methods are: 1, "$.ajax ()" method, used to execute asynchronous HTTP (Ajax) request; 2, "$.get ()" method; 3, "$.post ()" method; 4, "$.getJSON ()" method; 5, "serialize ()" method, and so on.

The operating environment of this tutorial: windows7 system, jquery1.10.2 version, Dell G3 computer.

Native AJAX requests are sent in native JavaScript, which is very tedious, and it is easier and faster to use jQuery.

Native AJAX request

AJAX requests in JQuery

$. Ajax method

Url indicates the requested address

Type indicates the type of request, GET or POST request

Data indicates that there are two formats of data sent to the server: one: name=value&name=value two: {key:value}

Success request succeeded. Callback function of the response.

Data types commonly used in dataType responses are: text for plain text xml for xml data json for json objects

$. Get method and $.post method

Url address requested by url

Data sent by data

Successful callback function of callback

The data type returned by type

Because get or post already specify the type of request, there is no need to pass in the type parameter

$. GetJSON method

Url address requested by url

Data sent by data to the server

Successful callback function of callback

In the same way as before, you specify the type of request and the type of data returned, so you can pass two less parameters.

Form serialization serialize ()

Serialize () can get the contents of all the form items in the form and splice them together in the form of name=value&name=value.
