POPUP

[basha khan]

1) I have a Struts action with some fields.
2) When a button press, I have to open a new Javascript popup window.
3) That window have "OK" and "Cancel" Buttons.
4) I want to submit the form if user press "OK" else i want to forward to another page.
5) I dont want to use javascript alerts. But popup window.

I think this is a regular problem. Anyone knows?.

Thanks
Basha

Why not use the javascript confirm() method? It has both an OK and a cancel button and is ready-made for this type of operation. If you still don't want to use it, you can create a popup window using the window.open() method. You can then create an html page to be displayed in this new window with an Ok and Cancel button. In the on click method for your buttons, you can refer back to the window that opened the popup using the property window.opener.

No way to use confirm().

I tried window.opener before posting here. javascript in new window(popup) cant recognize the form i use in the parent window. (document.parentwinowform.element[0].value or document.parentwinowform.myelement.value not displaying anyting and gives error). becoz it cant recognize that form.

How do u send the parameter(URL parameter) while creating JS popup window.Now i given full path(just for testing). Context relative path does'nt working(eg /myapp/mypopup.jsp).

what's the way to make JS(javascript)recognize my parent window form?.

Thanks for ur help.

As I stated before, you must use window.opener to refer to any object in the window that opened the current document. In the example you gave, the reference would be: window.opener.document.parentwinowform.element[0].value. I know this works, because I use it often.

It is also possible to use a relative path to your jsp. It's the same as any other reference in a web application. The path is relative to the current page, so if the current page is in /myApp/, the reference would simply be "mypage.jsp"

so if the current page is in /myApp/, the reference would simply be "mypage.jsp"

My context is

/mycontext.

The jsp in

/mycontext/jsp/myjsp

popup in

/mycontext/jsp/mypopup.jsp

When i give the path /jsp/mypopup.jsp, window is opening. But not getting reference to parent window form(window.opener.document.parentwinowform.myelement.value gives error).

If i use just "mypopup.jsp" or "/mypopup.jsp" as URL parameter, new window says URL does'nt exists. So it needs path from context path(rest of the path after context).

Any solution?.

Please the portions of your main window you're trying to access, as well as the javascript code in the popup window you're using to access it, as well as the javascript error message you get when you try to run the code. This might help pinpoint what the problem is.

Also, here's a link the explains in greater detail how to use the "opener" property.

Simple!!. The actionform was renamed and i forgot that. LOL.

The problem was that i have previousely mentioned. window.opener does'nt reference to parent window. But that's becoz actionform was renamed. document.forms[0] works well. I dont touched JS for years. So i thought it can be a JS issue. Was not confident abt this loosely coupled language.

After playing sometime with JS, i started liking it. It's cool.

Good link. Thanks.
