我想继续一些其他问题：
How does jquery mobile hide mobile safari's addressbar?
这将在页面加载后隐藏地址栏。
但是，这是我的新问题：
如果我向上滚动以重新显示地址栏，则在向下滚动页面时地址栏不会隐藏。
所以，基本上，我想在页面向下滚动时隐藏地址栏。
最佳答案
解
我想到了滚动位置，并最终得出以下结果：
var touchHeight = $('.mobile-touch-overflow').height(),
screenHeight = utils.getScreenHeight() - (utils.notStandalone()?44:0);
// touchOverflow: hide adressbar when scrolling
if(touchHeight > screenHeight && utils.supportTouchOverflow())
{
$('.mobile-touch-overflow').bind('touchmove',function(){
if($('.page-content').offset().top < 0)
{
utils.windowScroll(1);
}
return true;
});
}
