c# - Close child windows from postbacked parent window -

I need to close the child window that has been loaded from a native window.
Hair window to window.open () method.
I need to close this hair window by clicking a logout button or close button that is in the original window.
My code:


  var childWin = []; // hair window open event function child_open (url) {childWin [childWin.length] = window.open (url); } // a logout button or close button event function parent_close () {for (i = 0; i & lt; childWin.length; i ++) {if (childWin [i] == faucet) returned incorrect; ChildWin [i] .close (); } Window.close (); }   
 If you do not postback to the parent window server then this code is OK. When a postback occurred in the original window, the value of the variable (childwin) disappeared and I can not close the hair window with this code. 
 The problem is -  Parents want to stop postbacked children too.  Is there a solution for this? 
 Thanks for all your interests and answers.   
 
 
 Your array will clear the child every time the page is loaded. So back in the array there will be nothing. This is the reason why hair windows are not being closed.  
 A work has been mentioned around  
 Try to do something like [Nothing was tested, and it will not be ensured that it will work, just give a try )]  
  Original window (all pages)   
  var childStatus = {};   
  hair window   
  var timerHandler, windowName = window.name, popupHandle = ""; Funciton ChildCallBack () {try (if popupHandle == "popupHandle == null) {popupHandle = window.opener.childStatus [windowName]; // ChildCallBack (); // There is no need for silkback, because we already have a timer {else} window.opener.childStatus [windowName] = popupHandle; }} Hold (e) {}} timer handler = window.setInterval (ChildCallBack, 500); Function window_onclose () {try {window.clearInterval (timerHandler); Window.opener.childStatus [windowName] = Faucet; } Hold (e) {}} window.onclose = window_onclose;   
  Your child window open function   
  // child window open event function child_open (url) {var winHandle = window open (URL, "Give some unique names for every window here"); WinHandle.popupHandle = winHandle;   
  Your close button event   
  // a logout button or close button event function parent_close () {for ( Key position in the key key () (childStatus [key]! = Null] {childStatus [key] .close ();}} Window.close ();}   
   Potential improvements for the query> But, after a child's postback, an error occurs in parent_close (), the value of childStatus [key] is not an object, and it can not be done to the childSatatus [ Key]. Close ())    
 Change    timer handler = window.setInterval (ChildCallBack, 100);     
  if (popupHandle == "" || popupHandle == null ) {// Get PopupHolders from Point Window PopupHandle = window.opener .childStatus [windowName]; TimerHandler = Window.SetInternval (ChildClackback, 100);}
