ExtJS无法解码JSON消息

Question

I'm using ExtJS to make an Ajax request to server-side, and then I would like to parse the JSON response and do something with it.

The problem is the i can't decode the response text:

Ext.Ajax.request({
                                    url: 'Applications/GetFarmCounters.aspx',
                                    params: { farm: 'test', farmid: Ext.getCmp('farm_id').getValue() },
                                    success: function (result, request) {
                                        // result.responseText is here : {succes : true, message : 'test'}

                                        var jsonData = Ext.util.JSON.decode(result.responseText);

                                        Ext.MessageBox.alert('Success', 'Decode of stringData OK<br />jsonData.message= ' + jsonData.message);

                                    },
                                    failure: function (response, opts) {
                                        Ext.Msg.alert('Warning', 'Error!');
                                    }
                                });

But instead of seing the "test" message in an alert box, i get this error message in Chrome developer tools : "Uncaught SyntaxError: Unexpected token s"

What am i doing wrong?

Thank you!

Answer 1

It's a JSON issue

{
    "success": true,
    "message": "test"
}

should be the JSON you return. Always test your JSON using JSONLint
