a problem in ST2.0 on Ext.decode(json string).Help!

[gracethief]

var json='{"a":"\d{4}"}';
var d=Ext.decode(json);

then I got a object d with a property a which value is 'd{4}', the '\' was lost. but this worked properly in ExtJs.

Could anybody help me to solve this problem?

From first glance I would say that your string is not encoded properly I managed to get the result you wanted with:

var json=Ext.encode('{a:\"\\d{4}\"}');
var d=Ext.decode(json);

I was just interested in you problem (I like puzzles ) so I hope I'm of help and not hinderance!
