For help, Jqueryajax url issue in yii, urgent yii Jquery ajax url

I want to pass the value to the backend controller method, but I cannot write the url.

Var data = "name =" + val;
// Alert (data); error: function () {alert ('error ');}

$. Ajax ({
Type: 'post ',
Url: "http: // localhost/message/www/index. php? R = home/CkUser ",

Data: data,
Success: function (msg ){
Alert ('MSG ');
$ ("# Nameinfo" cmd.html (msg );

},


}
The following is the action method:
Public function actionCkUser (){

// $ Name = $ _ POST ['name'];

$ Name = Yii: app ()-> request-> getParam ('name ');
Echo $ name. 'BB ';
$ Model = new User;
If ($ name)
{
$ Model-> username = $ name;
$ User = User: model ()-> find ("username = '{$ this-> username }'");
$ Result = '';
If ($ user)
{
$ Result = 'User already exist ';
Echo 'user already exist ';
}
Else
{
$ Result = 'OK ';
Echo 'OK ';
}
Return $ result;
}
Yii: app ()-> end ();
$ This-> render ('ckuser', array (
'Model' => $ model,
));
}

What can I see when I open this address?
Http: // localhost/message/www/index. php? R = home/CkUser

What can I see when I open this address?
Http: // localhost/message/www/index. php? R = home/CkUser

Which view page is displayed?

When debugging ajax:
Or you can perform the ajax operation based on the framework.
Or leave the framework to write a separate server program.

Url: "http: // localhost/message/www/index. php? R = home/CkUser ",

Data: data,
Success: function (msg ){
Alert ('MSG ');
$ ("# Nameinfo" cmd.html (msg );

},

}); // Parentheses are missing here

$ (Document ). ready (function () {data = 'name'; $. ajax ({type: 'post', url: "http: // localhost/message/www/index. php? R = home/CkUser ", data: data, success: function (msg) {alert ('MSG '); $ ("# nameinfo" cmd.html (msg) ;},}); // parentheses are missing here });

I am missing the paste, not the problem.

Url :"? R = home/CkUser ",

You can use this code to run normally. didn't you load jquery?

Run the code in firebug and you will not be able to see the problem.
