问题
I've checked the jQuery mobile API documents and GitHub Issues but I can't find the answer to my question.
I've created a web app with the latest version of jQuery Mobile. The menu is a side panel that is opened when a link in the header is clicked. The header is fixed on top of the page.
In Safari & Chrome on iOS 7, when I scroll down the page and then open the side panel to get the menu, the page scrolls back to the top.
Is there any way to have the panel open without having the page scroll back to the top?
Thank you very much for your help!
Here is the code I use :
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-status-bar-style" content="black" />
<title>Sentinelle</title>

Here is the solution for futur googlers :
The link to open the panel should be :
<a href="#mypanel" class="jqm-navmenu-link ui-btn ui-btn-icon-notext ui-corner-all ui-icon-bars ui-nodisc-icon ui-alt-icon ui-btn-left">Menu</a>
With the div for the panel set as :
<div data-role="panel" id="mypanel" class="jqm-navmenu-panel" data-position-fixed="true" data-position="left" data-display="overlay" data-theme="a" style="overflow:scroll; position: fixed;" data-animate="true">
See http://api.jquerymobile.com/panel/#option-positionFixed
回答2:
<a href="#" class="jqm-navmenu-link ui-btn ui-btn-icon-notext ui-corner-all ui-icon-bars ui-nodisc-icon ui-alt-icon ui-btn-left">Menu</a>
The a href ="#" Will always go to top, you will have to change this.
