Question

I am currently working on developing custom dialog box to be used with my application using jQuery. The problem is that the call to create dialog is asynchronous i.e. the line of code after it is executed before it is displayed. Here is what I have done, I have created a function DisplayConfirm() which when called creates a modal dialog. I want to use it like the following:

if(DisplayConfirm()){
//do this
else
// do that

But I cannot because the line of code written after DisplayConfirm() is executed before the dialog is even created. How can I synchronize this operation so that I don’t have to use callback functions?

Answer 1

You cannot write a function in javascript that interacts with the user and blocks the javascript interpreter. confirm can do that because it is a browser built-in, written in C++ (or whatever).
