This may seem obvious to make a pop-up with jQuerymobile with its popup API, but its a little more than just calling the api.
The problem is closing the popup. When working in a single page application in jQuerymobile and phonegap, the closing of the popup will take you to different jQueryMobile pages depending upon your setup.
The solution is to make the popup ready to be open just at the current page and while closing it should not make the application go to different pages. The trick is to while initialising the popup widget, initialise it with “{history: false}”, and thats all.
Here is a popup created with jQueryMobile API.

		Save
		Cancel
	

Here is the javascript code to initialise the widget and open it.

//making a popup which will not take you back to the previous page.
$('#popupDialog').popup({history: false});//awesomeness
$('#popupDialog').popup('open');

Happy coding
