jquery refresh the page-based approach, and some javascript functions

jquery refresh the page partial refresh:

This method more to go, and often there are several;

$. get method, $. post method, $. getJson method, $. ajax as follows

The first two use basically the same

$. get ( "Default.php", (id: "1", page: "2"),
function (data) (
/ / Here is the callback method. Returned data data. Here like how handle how handled.

$. getScript methods:

$. getScript ( "http://jqueryajax.com/jquery.js",
function () (
$ ( "# Go"). Click (function (){// callback methods
$ ( ". Block"). Animate ((backgroundColor: 'pink'), 1000)
. animate ((backgroundColor: 'blue'), 1000);

$. getJson only return data type is not the same as

$. getJson ( "Default.php", (id: "1", page: "2"),
function (data) (
/ / Note that the returned JSON data reference method "data.info", do not understand can check out the json in tutorial. Here is not to explain too much

$. ajax this approach is estimated using a lot of people bar. But I not like use this. Personally feel that the first two more convenient

$. ajax ((
type: "POST", / / submitted to the type of
url: "some.php", / / submit address
data: "name = John & location = Boston", / / parameter
success: function (msg) (/ / callback method
alert ( "Data Saved:" + msg); / / Here is a method and content, and above get the same way as

Here are full-page refresh method: may sometimes be used
window.location.reload () Refresh the current page.
parent.location.reload () refresh the father object (for frame)
opener.location.reload () refresh the parent window object (for the single open window)
top.location.reload () refresh top objects (for multi open windows)
