I need to show popup info message with single close button, but content is located in separate html file. The current implementation using window.open not working for many users with popup blockers.
My question is which tool/framework should I use.
It pointed me to
jqModal - looks what I need.
You can pass the URL (e.g. $.jqm({ajax:'remote/dialog.html'}) or extract it from an attribute of the triggering element. For instance, $(.jqm({ajax:'@href'}) would grab contents from bar.html if the triggering element was <a href="foo/bar.html">
In particular see example 3b example-alert.
