We are facing issue when we are parsing a json data.

Below is the function which throws error

parseJSON: function( data ) {

Attempt to parse using the native JSON parser first

if (window.JSON && window.JSON.parse) {

return window.JSON.parse( data ); We are getting error from this line due to data is undefined

}

if (data === null) {

return data;

}

if ( typeof data === "string" ) {

// Make sure leading/trailing whitespace is removed (IE can't handle it)

data = jQuery.trim( data );

if ( data ) {

Make sure the incoming data is actual JSON

Logic borrowed from http://json.org/json2.js

if ( rvalidchars.test( data.replace( rvalidescape, "@" )

.replace( rvalidtokens, "]" )

.replace( rvalidbraces, "")) ) {

return ( new Function( "return " + data ) )();

}

}

}

jQuery.error( "Invalid JSON: " + data );

}
