问题
I'm creating a mobile app targeted for iPad Mini. I have a panel that slides out from the left with navigation menu. I also have the need for a back button in the header. What is the best practice for buttons in the header? I need a back button at certain times in the flow of the application and I also need the button that opens the panel in the header too.
Thanks for your advice.
I forgot to mention the right side of header has a button that loads barcode scanner. So, I'm left with left side of header to compete for 2 buttons.
回答1:
Header can accommodate two buttons on right and left, ui-btn-left and ui-btn-right respectively.
However, you can place more than two buttons in header by using controlgroup widget with data-type="horizontal" attribute.
<div data-role="header">
<!-- right-hand button -->
<a href="#" class="ui-btn-right" data-icon="bars">Bcode</a>
<!-- if you don't want to use title,
replace it with <span class="ui-title"></span> -->
<h1>Header</h1>
<!-- left-hand button -->
<div data-role="controlgroup" data-type="horizontal" class="ui-btn-left">
<a href="#panel" data-role="button" data-icon="star">Panel</a>
<a href="#" data-role="button" data-icon="back">Back</a>
</div>
</div>
