问题
We are developing an application with the layout near to the jqm examples here( table of contents on left and contents at right) but we want the same behavior as Sencha mobile, when it's in portrait, the table of contents collapses in a navigation button here
Is it possible to do with jqm?
回答1:
I have created a sample jQuery Mobile application which works like this - When in portrait mode,a split view layout will be shown.When in landscape mode,navigation can be done via a button in the header.For illustrating this in a desktop browser,I have given the width to check as 500px.If width>500 px ,split view. If width <500px, button in header.
This is the source code:

This is not a foolproof application.But just a rough copy to illustrate how this feature can be done.There are still lot of things to be done to make this work perfectly.
To make it work I have used the concept of media queries.Using it you can selectively hide/show the layout depending on the browser width(orientation of device).
P.S. I have used jqm-docs.css for this example.This css has other media queries too targeting other widths.So there might be some weird layout issues when you test this code.Please modify that css to remove the unwanted media queries.
Let me know if it helps
