Answer 1

你可以使用orientationchange jQuery Mobile事件,然后做一个

window.location.reload(); 

刷新页面.

例如:

$(function(){

// Set Inital orientation
// get the initial orientation from window which
// returns 0 for portrait and 1 for landscape
if(window.orientation == 0){
    var ori = "portrait";
}else{
    var ori = "landscape";
}
changeOrientation(ori);

// Orientation Change
// When orientation changes event is triggered
// exposing an orientation property of either
// landscape or portrait
$('body').bind('orientationchange',function(event){
    changeOrientation(event.orientation)
})

// Change the style dependengt on orientation
function changeOrientation(ori){
    // Remove all classes separated by spaces
    $("#orientation").removeClass('portrait landscape');
    $("#orientation").addClass(ori);
    $("#orientation").html("<p>"+ori.toUpperCase()+"</p>");
}

});
