title: jquery can do this? popup window for value
body: <p>I used JavaScript to open a new window(child)  when user clicks on button from parent window.</p>
  
  <p>On new window(child), I have textbox and button,  I need to get the value of the textbox and pass to parent window when user clicks on button, while closing the child window,  I need the updated value inserted into parent window (without refreshing parent window) so I can display my value to some hidden field/ label of the parent window , how can I do that? </p>
  
  <p>1- parent window has button, clicked child window opened
  2- child window has textbox and button, when button clicked, child will do a post to server to update database, then pass the value of textbox to parent window without refreshing parent window, and close child window.</p>
  
  <p>How can I do that? Is it can be done with simple JavaScript? 
  If I do it using jquery, will I have more benefit?
  Could anyone advice how can I do it?</p>
