Display an Overlay on Parent Tab (page) until all its child tabs (pages) are opened

Question

Suppose I have Parent Page.

When I click on Print a new tab (page) is opened for print preview.

What I want is when I click on print an overlay should be shown on parent tab (page) to stop further work until child tab is closed.

Because when print tab (page) (child) is opened, most of the functions on parent tab (page) are not working properly.

Note: I am using Google Default print/preview functionality.

I am not be able write the code to perform the above described scenario. How can I detect in parent page that its child page is closed?

Could you share some code? It sounds like you have already described the solution but are asking someone to write the code. I'm sure there are answers out there that will cover what you're asking. — Carl Reid, Oct 07 '15 at 08:07
Yes i need a code :( i don't know how to get the child tab to tell parent tab that `i am closing` ... — Waqar Ahmed, Oct 07 '15 at 08:11
`How can i detect in parent page that its child page is closed` By child page, do you mean browser print dialog? EDIT: ok i see, you open it in new tab BUT could you share this js code at least?! — A. Wolff, Oct 07 '15 at 08:17
its simple! `Print` when that page is reloaded `window.print()` is called. — Waqar Ahmed, Oct 07 '15 at 08:28

You can use dialog in jQuery follow this link to view or you might use in your code like

var childNode= window.open('/uri of child');

then use

childNode.onunload = function(){  
// code after child closed
}

if not then you can also try

window.onunload = function() {if(!window.opener.closed && childNode.closed){
//code after child closed
}}
