Question

On a submit button click, I want to open a child window and redirect the parent window to another location.

To do that, I have used the code for opening child window:

<button class="btnBg" onclick="window.open('<%= url_for(:action=>"index") %>', '', 'toolbars=0')">

Can you please tell me how to redirect the parent window to a desired location?

Answer 1

The easiest way is to assign something to window.location in your JavaScript (but be sure to do that after opening your new window):

<script type="text/javascript">
    function open_and_redirect() {
        window.open('<%= url_for(:action=>"index") %>', '', 'toolbars=0');
        window.location = 'the new location for the parent window';
    }
</script>
<button class="btnBg" onclick="open_and_redirect()">

You don’t need to use a separate function though, I just did that to make it easier to read.
