This article is about the usefulness of the post () method. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

JQuery.post (url [, data] [, success (data, textStatus, jqXHR)] [, dataType])

Description: use an HTTP POST request to load data from the server.

Url

Type: String

A URL string containing the sending request

Data

Type: PlainObject, String

A string or Key/value key-value pair sent to the server.

Success (data, textStatus, jqXHR)

Type: Function ()

The callback function that is executed when the request is successful.

DataType

Type: String

The expected data type returned from the server. Default: intelligent judgment (xml, json, script, or html).

This is an abbreviated form of the Ajax function, which is equivalent to:

$.ajax ({

Type: "POST"

Url: url

Data: data

Success: success

DataType: dataType

})

The success callback function passes in the returned data, which is a response based on the MIME type. The data types it may return include XML root nodes, strings, JavaScript files, or JSON objects. A string describing the status of the response is also passed in.

Starting with jQuery 1.5, the success callback function also passes a "jqXHR" object (in jQuery 1.4, it passes a XMLHttpRequest object).

Most implementations will specify a successful handler:

$.post ('ajax/test.html', function (data) {

$('.result') .html (data)

})

All the HTML code snippets requested by this example are inserted into the page.

Pages fetched with POST are never cached, so the cache and ifModified options in these requests are not valid in jQuery.ajaxSetup ().
