Ajax json request Receiving and Processing Based on Yii

(Original: http://lei3056.blog.163.com/blog/static/39532279201181105142902)

CGridview:

Array (

'Name' => 'remark ',

'Type' => 'Raw ',

'Value' => 'chtml: textField ("remark", $ data-> remark, array (

"Size" => 7,

// "Readonly" => "readonly ",

"Class" => "textfix ",

"Id" => "$ data-> id ",

))'

),

This paragraph is correct. Make up now.

View: unoutput

Yii: app ()-> clientscript-> registerScript ('posiiton ','

JQuery ("# person-grid. textfix"). live ("change", function () {// jquery's live method is actually a lot of JavaScript websites.

If (! Confirm ("are you sure you want to fix this data? ") Return false;

Var id = $ (this). attr ("id ");

Var val = $ (this). val ();

$. Ajax ({

Type: "POST ",

DataType: "json", // dataType (xml html script json jsonp text)

Data: {"id": id, "val": val}, // json data

Url: "'. Yii: app ()-> createUrl ("/admin/person/updateremark/").'", // address generated by YII

Success: function (json) {// json object is also obtained successfully

// $. Fn. yiiGridView. update ("ad-grid ");

Alert (json. val); // val attribute in the object

$ (This). val (json. val );

// Alert ("success ")

}

});

Return false;

});

');

Html: output the final result

JQuery ("# person-grid. textfix"). live ("change", function (){

If (! Confirm ("are you sure you want to fix this data? ") Return false;

Var id = $ (this). attr ("id ");

Var val = $ (this). val ();

$. Ajax ({

Type: "POST ",

DataType: "json ",

Data: {"id": id, "val": val },

Url: "/admin. php? R = admin/person/updateremark ",

Success: function (json ){

// $. Fn. yiiGridView. update ("ad-grid ");

Alert (json. val );

$ (This). val (json. val );

// Alert ("success ")

}

});

Return false;

});

Controller: receives json ajax requests

Public function actionUpdateRemark (){

If (Yii: app ()-> request-> isAjaxRequest) {// whether to request ajax

$ Id = (int) Yii: app ()-> request-> getParam ('id'); // getparam will get the get post variable, you can also receive json-processed variables.

$ Val = Yii: app ()-> request-> getParam ('val ');

$ Model = $ this-> loadModel ($ id );

$ Model-> remark = $ val;

If ($ model-> save ()){

Echo CJSON: encode (array ('val '=> $ model-> remark); // The Yii method processes the array into json data

}

}

}

In addition, the editing are all in the UTF-8 environment, there is no garbled problem.

In JS data transmission under IE, JQUERY and YII are both doing well. If GET is used, there will be a problem in Chinese, and there will be no problem in JSON.
