exception handling in javascript

Hi All, I'm going to explain exception handling in JavaScript

Today's, I have a requirement to exception handling in JavaScript and want to send the error messages and stack to support team for solving to the problem.

That time, we can use to try/catch/finally and get the exact error and send to the support team.

In the 1st step, Code Sample for Exception Handling in JavaScript Application

try

{

    $('#progressBar').block();

    //Todo: Application logic here.

}

catch (ex) 

{

    console.log(ex.message);

    console.log(ex.stack);

    //Call to track exception method to stor the exception and print.

    getEceptions(ex);

}

finally 

{

       $('#progressBar').unblock();

}

//Get exceptions method.

function getEceptions(ex) {

    var self = this;

    self.message = ex.message;

    self.stack = ex.stack;

};
