你是在设备上还是在桌面上进行测试？检查chrome中的小提琴链接，它工作正常。Ipad和平板电脑中的设备相同。@sheetal在chrome上工作正常。但问题在设备上。在IOS和Android设备中。检查此答案

1) Go into jquery.mobile-1.x.x.js

2) Find $.mobile = $.extend() and add the following attributes:

last_width: null,
last_height: null,
3) Modify getScreenHeight to work as follows:

getScreenHeight: function() {
    // Native innerHeight returns more accurate value for this across platforms,
    // jQuery version is here as a normalized fallback for platforms like Symbian

    if (this.last_width == null || this.last_height == null || this.last_width != $( window ).width())
    {
        this.last_height = window.innerHeight || $( window ).height();
        this.last_width = $(window).width();
    }
    return this.last_height;
}
