Opening New Window, blocking the current window

Copy linkTweet thisAlerts:

Hi all,

We can open a new window through JavaScript using windows.open().

Can we block the original window from which this window was opened until we close the new window?

Thanks in advance

1.put a time based function in your parent window using setInterval("some_function","time").This "setInterval" should be set only when you open the child window,

2. Pass a flag variable to your child window. for eg. flag=false;

3. use onbeforeunload in your child window and set the flag to true.

4. In the parent window check for this flag. If flag is false use "new.document.focus()" which will focus the document of the child window.

Thanks for the reply. Can you provide some code sample for this.

@sridhar_423Jan 21.2006 — Parent Window:

<body onfocus="chkCildWin()">

<input type=hidden name=flag value=false>

<input ... onclick="winopen()">

var newwin=null;

function winopen(){

newwin=window.open(url,ChildWindow,params);

}

function chkCildWin(){

if(newwin!=null){

if(document.formname.flag==false)

newwin.document.focus();

}

}
------------------------------------------------------


ChildWindow Page:

<body onbeforeunload="SetVal()">

function SetVal(){

window.opener.document.formname.flag=true;

}

------------------------------------------------------

Success!
