我遇到了一个奇怪的视觉问题。我希望在应用程序更换页面时能有一个好看的过渡效果。 不幸的是，当我第一次切换到另一个页面时，当前页面并没有滑动出去，而是立即被新页面替换，然后才滑动出去。当第一个页面不再显示时，新页面才被显示出来。但第二次尝试就会像魔法般地正常运行！
这是在 iPhone 上使用 jQuery Mobile + PhoneGap 运行的。
我制作了一个视频来帮助澄清这个问题：http://www.youtube.com/watch?v=Ybvzh_wTnSE

以及相关的CSS：

-webkit-user-select: none; /* prevent copy paste for all elements */
}
#container { width:320px; height:460px; overflow: hidden;}
input{ -webkit-user-select: text; /* enable copy paste for elements with this class */}
a {-webkit-user-select: none; /* prevent copy paste for all elements */}
span {-webkit-user-select: none; /* prevent copy paste for all elements */}
#side-menu {z-index: 1000 !important; position: fixed; height: 460px; width: 56.5px; background: url(../img/bg_big.png) no-repeat; display: inline-block;

#slide_mask{ display: inline-block; overflow: hidden; padding-left: 56.5px; width: 263.5px; height: 460px; top: 0;}
还有一点JS代码：
///////////////////////////////////
//MENU MECHANICS
///////////////////////////////////
function showdives(){
$("#side-menu .selected").removeClass("selected");
$("#header_dives").addClass("selected");
}
function showexplore(){
$("#side-menu .selected").removeClass("selected");
$("#header_explore").addClass("selected");
}
function showsearch(){
$("#side-menu .selected").removeClass("selected");
$("#header_search").addClass("selected");
}
function showsettings(){
$("#side-menu .selected").removeClass("selected");
$("#header_settings").addClass("selected");
}
onclick 方法仅向菜单项添加/删除“selected”类。
