Hi, all

In javascript
I need to close all the child windows[popup windows] that I have opened through a parent window

Scenario:
Here I will be having as many as child window opened and name given to the child window can not be tracked because each will be having a different name, and

I am using 70 to 80 popup windows [doing separate operations] through out my page [parent window]

There can be any number of child windows opened , at the time of user triGgers the event from the parent window to close all the child window that I have opened so far [currently opened child windows]

Create an array to track the open windows.
Whenever you open a window, pass the handle to that window to a function that will add it to the array. When you want to close all the windows, loop through the array and close them. You don't need to worry if a child window is closed or not. The following code was quickly tested on IE 6 and FF 2. The closeWindows function would need to be called in the onunload event.



<html>
<head></head>
<body>
<script>
//The openWindow array will hold the handles of all open child windows
var openWindow = new Array();

//Track open adds the new child window handle to the array.
function trackOpen(winName) {
openWindow[openWindow.length]=winName;
}

//loop over all known child windows and try to close them. No error is
//thrown if a child window(s) was already closed.
function closeWindows() {
var openCount = openWindow.length;
for(r=0;r<openCount;r++) {
openWindow[r].close();
}
}

//Open a new child window and add it to the tracker.
function open1() {
var win1 = open("http://www.yahoo.com");
trackOpen(win1);
}

//Open a different child window and add it to the tracker.
function open2() {
var win2 = open("http://www.google.com");
trackOpen(win2);
}
//Open whatever the user enters and add it to the tracker
function open3() {
var newURL = document.getElementById("url").value;
var win3=open(newURL);
trackOpen(win3);
}

</script>

<input type="button" value="Open 1" onclick="open1()"><br>
<input type="button" value="Open 2" onclick="open2()"><br>
URL: <input type="text" id="url">&nbsp;<input type="button" value="Open URL" onclick="open3()"><br>
<input type="button" value="Close All" onclick="closeWindows()">

</body>
</html>


Hope this helps.

I will open a report from a button click event and I want to close the same window when I user clicks to generate the report again.

One Button ----> click -----> report generation(in popped up page)
For pop up page I use clientsidescript.registerstartupscript in c#.net
Now he goes to parent page and selects other report then I have the already popped up windows creating problem sometimes. Please let me know to use the same to open for the first time.

Close it and open the same for other or same report.

Thanks,
Suman

Give the window a name and use the same name every time you opent he report. It will automatically overwrite the old window.

Open(url,"report");
