[sajan]

Hi,
I am facing some problem decoding JSON String.
I am sending this JSON
{\"success\":true,\"data\":[{\"key\":"+String(113556)+"}]}

but I dont know how to decode it on success function.

every time it shows error.
Can you please suggest how to decode JSON String.

thanks in advance

success: function (response, opts) {
	 var obj = Ext.decode(response.responseText);
}

Hi,
I already did till that.
I wanted to get the values.
If I do console.log(obj) it still says undefined.

How to get the values out of it?
Please do let me know
thanks

 success: function (response, opts) {
    var obj = Ext.decode(response.responseText);
    var objCount = obj.totalCount;

    var name = obj.items[0].name; //this is what I use cause I return items, 

    var key= obj.data[0].key;  // I think this would be what you would use


}

also your json i don't think should have those slashes in there. maybe you are getting bad json back

ex. {"totalCount":1,"items":[{"number":"374432"}]}

Hi,
My JSON is being returned as

{"success":true, "totalCount":1,"items":[{"name":1334163657}]} (I followed your suggestion)

but still the code lines

var objCount = obj.totalCount;  


and 
    var name = obj.items[0].name; //this is what I use cause I return items,

is showing error.
It is showing errors as

Uncaught TypeError: Cannot read property 'totalCount' of undefined

&
Uncaught TypeError: Cannot read property 'items' of undefined

I am still unable to figure out the error. Searched a lot of place but no solution till now!! Please help
thanks

Use a debugger.

Stop on errors, what is obj? Is it still a string at that point? Does it need to be converted to an object?

[sajan]

Hi,
Yes !! debugging it.
On Place where it shows error

success: function(response, result) {
 var responseData = Ext.decode(response.responseText);/// it says responseData is undefined screenshot attached
 var objCount = responseData.totalCount;
        var name = obj.items[0].name; 
Ext.Msg.alert(name)

So after that all lines failed. I am new to this. Previously while doing extjs I used firebug but now since sencha is not compatible with chrome. I am facing trouble all the way.
Cannot procede until I resolve this.
So please help me
thanks

So whats the value of response.responseText?

[sajan]

Nothing,
But I just figured it out

I just did this

 var name = result.items[0].name;

        Ext.Msg.alert('success',name);

and it showed the value

So, I guess it worked!!!

thanks

glad you got it working!!

but you said "sencha is not compatible with chrome." Chrome is all I use to debug senchatouch and extjs4

I suggest chrome as a debugging tool
