Hi,

 

We are using jQuery 1.6.4 in our application and requested to upgrade to 1.9.0.

 

So I have upgraded to 1.9.0 along with jQuery migrate plugin to capture the errors and warnings.

 

I have fixed some issues which were occured due to the upgradation.

 

Now I am facing the below issues in json parse while navigating to a particular page.

 

syntax error: jquery-1.9.0.js which is pointing to the second line of below code (ie. return line)

 

return window.JSON.parse( data );

}

 

Also I found the below through google search:

 

Prior to 1.9, an ajax call that expected a return data type of JSON or JSONP would consider a return value of an empty string to be a success case, but return a null to the success handler or promise. As of 1.9, an empty string returned for JSON data is considered to be malformed JSON (because it is); this will now throw an error. Use the error handler to catch such cases.

 

I am very new to jQuery and not sure how to catch the error in this specific scenario.

 

Could you please help me on this to resolve?

 

Thanks,

Praveen DK
