jquery $.ajax Instance Details simple

This article tells you to use the $.ajax to interact with the database tutorial or asynchronous transmission of data, update data, delete data, etc. using the jquery Ajax to the example is very convenient, a few simple code on the OK.
Load JS
$.ajax ({
Type: "Get",
URL: "Test.js",
DataType: "Script"
});

Ajax Save Data
$.ajax ({
Type: "Post",
URL: "some.php tutorial",
Data: "Name=john&location=boston",
Success:function (msg) {
Alert ("Data saved:" + msg);
}
});

Ajax Save data Return value change HTM content

$.ajax ({
URL: "Test.html",
Cache:false,
Success:function (HTML) {
$ ("#results"). Append (HTML);
}
});

Load data synchronization. To prevent browser requests from being activated. Synchronization is necessary when the user's interaction is prevented by other means

var html = $.ajax ({
URL: "some.php",
Async:false
}). responsetext;

Example: An XML document sent to the server as data. Automatically converting data to strings can be avoided by setting the ProcessData option to false.

var xmldocument = [create XML document];
$.ajax ({
URL: "page.php",
Processdata:false,
Data:xmldocument,
Success:handleresponse
});

To send data to the server ID, save some data to the server and notify the user once it's done. Note that this usage-returns the result of the call to a variable-requires synchronization (blocking) of the request! (Asynchronous: false)

Bodycontent = $.ajax ({
      URL: "script.php",
      Global:false,
      type: "Post",
      data: ({ID: This.getattribute (' id ')},
      datatype: HTML,
      Async:false,
      success:function (msg) {
          alert (msg);
     }
  }
). responsetext;
