Jquery Ajax parse XML data (synchronous and asynchronous invocation) Simple instance _jquery

Copy Code code as follows:

$.ajax ({
Async:true,//default True (asynchronous request)
Cache:true,//default True, set to False will not load request information from the browser cache.
Type: "POST",//default: Get request mode: [Post/get]
DataType: "xml",//default ["XML"/"HTML"] returns data type: ["XML"/"HTML"/"script"/"JSON"/"JSONP"]
URL: "Test.ashx",//default current address, send the requested address
Data: {key: ' value '},//sent to the server
Error:function (XML) {alert (' Error loading XML document ' + XML);}, called when//request failed
timeout:1000,//Set Request timeout
Success:function (XML) {//Request callback function parameter after success: Server returns data, data format.
$ ("#users"). empty ();
Using jquery to process XML data
$ (XML). Find (' Table '). each (function () {
var LoginName = $ (this). Find ("LoginName"). Text ();
var Name "). Text ();
$ ("#users"). Append ("<li>" + LoginName + "-" + name + "</li>");
});
/*
$ (XML). Find (' user '). each (function (i) {
var LoginName = $ (XML). Find ("User LoginName"). EQ (i). text ();
var user name "). EQ (i). text ();
$ ("#users"). Append ("<p>" + loginname + "</p>" + "<p>" + name + "</p><br/>");
})
$ (XML). Find ("Student"). each (function (i) {
var id "); Fetching objects
var id_value=$ (this). Children ("id"). text (); Fetching text
alert (id_value);//This is the value of the ID.
Alert ($ (this). attr ("email")); Here you can display the email attribute under student.

The final output, this is Cssrain, seemingly more jq than Macnie
$ (' <li></li> '). HTML (id_value). Appendto (' ol ');
});
*/
}
})
