I want to have a javascript/jQuery popup window (child page) that is always in front of the parent page, something like facebook's current picture viewing feature.
it would be closed by the user clicking on the close button.
I have tried as below:
mywindow = window.open ("DownloadForm.aspx", "mywindow","location=1,status=1,scrollbars=1, width=350,height=150");
mywindow.moveTo(350, 350);
this code successfully opened a child page in front of the parent page, but there is jQuery code ( $(#test).click() ) on the parent page which causes the parent page to always be in front.
I tried putting the window.open() code after $(#test).click(), but it didn't solve the problem.
The $(#test).click() is necessary, therefore I need to have a workaround.
I appreciate any help, thank you in advance.
myWindow.focus()
Many modern browsers prevent this from working, but it's the only way.
use following javascript code in the page you are opening in popup
<body onblur="self.focus();">
Im sure you cannot control the order of the window. Instead of a popup (which is often and usually blocked by browsers) why not investigate using a lightbox javascript plugin. They are usually free, stylish and work well.
Just set it from the modal css. The z-index is normally set to 1. Just change it to 9999. That is the purpose of the z-index, to set the popup top level.
If not using bootstrap popup, then you need to use css to set it. Browsers are not guaranteed to place nice with .focus() on a window.
