html5 - Get variable from Sencha Touch Ext.data.JSONP.request response -

i'm trying boolean (success) , html string (result) response ext.data.jsonp.request, can't fgure out how. here's code have far:

ext.data.jsonp.request({     url: 'http://wereani.ml/shorten-app.php',     callbackkey: 'callback',     params: {         data: ext.encode(values)     },     success: function(response) {         console.log(response);         console.log(json.stringify(values));         console.log('link shortened');         if(response.responsetext['success'] == true) {         ext.msg.alert('link shortened', response.responsetext, ext.emptyfn);         } else {             ext.msg.alert('error', response.responsetext, ext.emptyfn);         }         form.reset();     },     failure: function(response) {         console.log(response);         console.log(json.stringify(values));         console.log('error');         ext.msg.alert('error', 'please try again.', ext.emptyfn);     } }); 

some sample json-p:

callback({"success":false,"result":"<div class=\"error\">please enter valid link shorten!<\/div>"}) 

the error i'm getting uncaught typeerror: cannot read property 'success' of undefined. in advance help!

edit: seems while response object {success: false, result: "<div class="error">please enter valid link shorten!</div>"}, response.responsetext undefined. using wrong variable? couldn't find documentation on response.

edit 2: seems reason console.log(response.responsetext) returning undefined because it.... was. jsonp-encoded variables (success , result) passed parsed automatically object, , response.responsetext never created (though think supposed be). solution read response.success , response.result directly!

answer: here's code worked. viswa help!

ext.data.jsonp.request({     url: 'http://wereani.ml/shorten-app.php',     callbackkey: 'callback',     params: {         data: ext.encode(values)     },     success: function(response) {         if(response.success === true) {             ext.msg.alert('link shortened', response.result, ext.emptyfn);         } else {             ext.msg.alert('error', response.result, ext.emptyfn);         }         form.reset();     },     failure: function(response) {         console.log('error');         ext.msg.alert('error', '<div class="error">please try again.</div>', ext.emptyfn);     } }); 

try this

ext.data.jsonp.request({     url: 'http://example.com/script.php',     callbackkey: 'callback',     params: {         data: ext.encode(values)     },     success : function(response) {       console.log("spiffing, worked");       // success property       console.log(response.success);       // result property       console.log(response.result);    },    failure: function(response) {         console.log(response);         ext.msg.alert('error', 'please try again.', ext.emptyfn);     } });
