Getting parameters from a pop-up window

Hi all,
Does anybody know how to work with pop-up windows in a jsp?

I could display a pop-up window by sending a value from the parent jsp as the request parameter. The jsp in the pop-up window takes this parameter and displays a set of values on the window depending on the parameter value. The user should select a value from these set of values.

Now I need to send the selected value back to the parent window as soon as I select a value in the pop up window. This pop up window also should get closed immediately.

I appreciate if anybody can tell me how to achieve this.

Thanks.

This is all client-side activity. Moving to the HTML/Javascript forum.

Now I need to send the selected value back to the parent window as soon as I select a value in the pop up window.

Your Javascript handler can reference the main page via the opener variable, which you can use to trigger any changes in the parent page.

To get started look at code below. Maybe this helps. 
Maybe there is a better way of doing it but atleast it should give you some idea of how this thing is done
 
<HTML>
<HEAD>
<SCRIPT LANGUAGE="JAVASCRIPT">
function doZoomback(sourceobj, destinationObj)
{
 
destinationObj.value=sourceobj.value;
window.close();
}
function doZoom(obj)
{
window.open("Zoomin.jsp?txttest=" + obj.value)
}
</SCRIPT>
</HEAD>
<BODY>
<form>
<input type="textbox" value="a very long text that i want to be displayed in text area" name="txttest">
<input type="submit" name="cmdOK" value="Zoom" on click="doZoom(txttest)">
</form>
</BODY>
</HTML>

Zoomin.jsp contents

<HTML>
<HEAD>
<SCRIPT LANGUAGE="JAVASCRIPT">
function doZoomback(sourceobj, destinationObj)
{
 
destinationObj.value=sourceobj.value;
window.close();
}
function doZoom(obj)
{
window.open("Zoomin.jsp?txttest=" + obj.value)
}
</SCRIPT>
</HEAD>
<BODY>
 
<TEXTAREA name="txtTest"><%=request.getParameter("txttest")%></TEXTAREA>
<input type="submit" name="cmdOK" value="OK" on click="parent.doZoomback(txtTest,opener.document.all.txttest)">
</BODY>
</HTML>

Thanks much for the reply.

Thanks for your reply too Rahul.

I could send a value back from the pop-up window.

Do you know how to send the user authentication information to the new window without embedding the password in the url?

Thanks again.

Thanks.

On the pop up page, include a javascript function which will be called on submitting the pop up box. Now you can populate the fields of the parent window or populate the value of any hidden field on the parent window by the javascript statement:
window.opener.document.<object_name (or form_name)>.value = <value_on_pop_up_page>;

Basically, window.opener.document will give you the document object of the parent page, and then you can play on further.

"suresh india"

There aren't many rules that you need to worry about here on the Ranch, but one that we take very seriously regards the use of proper names. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.

In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.

Since you have revealed that your real name is Suresh Parepall, that is the display name that you must use.

Thanks!
