How to call parent window function from child window jquery?

Question

i just need to call function in parent window while user is focusing on child window. i have this code in my parent window,

Answer 1

Try something like below:

parent.html

 
    
    
     
        Click here to open the child window
     

child.html

    
        
        
    
     
        
This is Child window
 
     

You should not do this on the parent, otherwise opener.CallParent() will not work, doing window.CallParent makes CallParent available as window scope:

function CallParent() {
  alert(" Parent window Alert");
}

And then you can simply call opener.CallParent(); not window.opener.CallParent();.
