$. Ajax () is the underlying ajax Implementation of jquery. For easy-to-use high-level implementation, see $. get, $. post, and so on.

There are several ajax event parameters: beforesend, success, complete, and error. We can define these events to process every ajax request.

$. Ajax ({url: 'stat. php tutorial ',

Type: 'post ',

Data: {name: "keyun "},

Datatype: 'html ',

Timeout: 1000,

Error: function () {alert ('error loading php document ');},

Success: function (result) {alert (result );}

});

Asp. aspx page code

Response. contenttype = "application/Webpage effects on"; response. write ("{result: '" + request ["name"] + ", hello! (This message comes from the server) '} "); jquery code:
$. Post ("ajax. aspx ", {action:" post ", name:" lulu "}, function (data, textstatus) {// data can be xmldoc, jsonobj, html, text, and so on. // this; // configure the options for this ajax request. For more information, see jquery. this alert (data. result) ;}, "json ");

 

Jquery. post (url, [daTa], [callback], [type]): uses the post method for asynchronous requests.
Parameters:
Url (string): the url of the request.
DaTa (map): (optional) data to be sent to the server, expressed in key/value pairs.
Callback (function): (optional) callback function when the load is successful (this method is called only when the response returns success ).
Type (string): (optional) the official description is: type of daTa to be sent. In fact, it should be the client request type (json, xml, and so on)
This is a simple post Request function to replace complex $. ajax. You can call the callback function when the request is successful. If you need to execute the function when an error occurs
