jQuery.post 方法与实例教程

jquery.post( url, [ data ], [ success(data, textstatus, xmlhttprequest) ], [ datatype ] )

returns: xmlhttprequest

jquery.post( url, [ data ], [ success(data, textstatus, xmlhttprequest) ], [ datatype ] )
乌拉字符串，其中包含的url的请求被发送。

dataa地图或字符串，发送到服务器的请求。
success(data, textstatus, xmlhttprequest)a callback function that is executed if the request succeeds.

datatypethe type of data expected from the server.

this is a shorthand ajax function, which is equivalent to:

$.ajax({
type: 'post',
url: url,
data: data,
success: success
datatype: datatype
});

这一成功是通过回调函数返回的数据，这将是一个xml根元素或文本字符串根据响应的mime类型。它还通过了响应文本的地位。

在jquery 1.4，成功回调函数也是通过xmlhttprequest对象。

大多数实现将指定一个成功的处理程序：

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

例如：请test.php教程网页，但忽略了返回结果。

$.post("test.php");

request the test.php page and send some additional data along (while still ignoring the return results).
请求test.php网页，发送一些额外的数据沿（同时仍忽略了返回结果）。
$.post("test.php", { name: "john", time: "2pm" } );

example: pass arrays of data to the server (while still ignoring the return results).
$.post("test.php", { 'choices[]': ["jon", "susan"] });

example: send form data using ajax requests
$.post("test.php", $("#testform").serialize());

example: alert out the results from requesting test.php (html or xml, depending on what was returned).
$.post("test.php", function(data){
alert("data loaded: " + data);
})

;example: alert out the results from requesting test.php with an additional payload of data (html or xml, depending on what was returned).
