How to make when a pop up is open, we are not allow to switch to primary
page until we close the popup page?

thanks.

this is in my opinion a great source for user annoyance. personally, I don't recommend it.

from main.html, startA function will popup a page and from popup page,
it will return a value to main.htm and alert the variable aaa.

However, we know that window.open and alert always start at the same time and hence we never capture the return from popup, so I make a
prompt to stop the startA keep running so computer have time to capture
the return values from popup.

But how to make user keep focus on popup page until it close?
otherwise, before they return value from popup, they can see the prompt
and can start the alert immediately before value(aaa) to return.

help.
thanks.

main.html

 
function startA() {
 
window.open("popup.htm");
 
check=prompt("process?");
 
if (check) {
alert(window.aaa);  //aaa is a variable return from popup page
}

popup.htm

window.opener.aaa="okok";

}

To answer the original question, you could use showModalDialog (where supported) or create your own version using DHTML (a pseudo-popup). It could be done with normal pop-up windows, but it will be annoying as pointed out by Dormilich.

Your main problem can easily be solved by using a button in the parent to alert the set value.
