How to manipulate JSON ResponseText in EXTJS

I have used the EXT.data.request to try to get text from a webpage with the following content:
[{"brand":null,"remark":null,"type":null,"id":120,"shop":null,"price":null,"model":null}]

The code I written to get the id value 120 is below:

conn.request({
url: 'json.htm',
method: 'POST',
success: function(response) {
var jsonData = Ext.util.JSON.decode(response.responseText);
alert(jsonData.id);
}
}); ....

After testing the code in browser, I failed to get the expected result, anyone can help?

unwrap your json object from the array brackets. :)

your id is inside an array so try this.

data[0].id;

Here is a very good site about json, http://json.org/. Read on.

{"brand":null,"remark":null,"type":null,"id":120," shop":null,"price":null,"model":null}

Thanks, but the reason I asked was because I have something in the form:
{"data": [{...}]}.

This was initialliy written for a JsonStore but now I also need it for a plain AJAX request.

I think it is more a syntax issue... I can't seem to figure out how to access the properties of "data".

unwrap your json object from the array brackets. :)

Hello,

Can you show a small example?

and jsonlint.com - to make sure your json is lint-tastic.
