The json filter converts a JavaScript object into a JSON string. This filter can be useful when debugging your applications. The JavaScript object can be any kind of JavaScript object.
The jQuery parseJSON() method takes a JSON string and returns a JavaScript object. The specified JSON string must follow the strict JSON format. Passing an incorrect string will cause a JS exception. Some of the examples of malformed JSON strings that can cause an exception on passing are given as follows -
A common use of JSON is to exchange data to/from a web server. When receiving data from a web server, the data is always a string. Parse the data with JSON. parse() , and the data becomes a JavaScript object.
This is how you should do it : ( for google find)
$([ {"name":"Lenovo Thinkpad 41A4298","website":"google222"}, {"name":"Lenovo Thinkpad 41A2222","website":"google"} ]) .filter(function (i,n){ return n.website==='google'; }); Better solution : ( Salman's)
$.grep( [{"name":"Lenovo Thinkpad 41A4298","website":"google"},{"name":"Lenovo Thinkpad 41A2222","website":"google"}], function( n, i ) { return n.website==='google'; }); http://jsbin.com/yakubixi/4/edit
