Stop execution of script when Messagebox opens.

I have a confirm MessageBox in my page. I what to execute a function on click of "yes" and other function on click of "Cancel" and there are other lines below the messagebox. When message box opens, the line below it executes.

I want to execute the lines below messagebox after the function of yes or cancel (as it is in javascript confirm function).

How can I achieve this or is there some other control for this kind of operation?

JSBin.

Thanks,

Shashi
