Question

Is there any way to create blocking dialog box using Javascript/JQuery/Ajax …

I have used the JQuery UI dialog box. As this is an asynchronous function, I used callback functions. However it makes a simple JS code of if/else very complex.

e.g.

ans1 = confirmBox("something"); 
 if(ans1){
    ans2 = dialogBox(); 
    if(ans2)
        alertBox();
    else {
        ans3 = dialogBox(); 
        ....
    }   
 }  
 else {
 }

… rest of the code

Callbacks make this very complicated. Is there an alternative to this?

Answer 1

There is no way to make JavaScript block and wait for a condition. You need to use the callback method.

Maybe if you are needing all of these steps, it would be better to do it in a different manner.
