公共js方法如下：

//內容自適應視窗大小
function resizeEle(ele, isResetH, IsResetW) {
    var windowWidth = getPageSize()[2];
    var windowHeight = getPageSize()[3];
    if (isResetH !== null)
        $(ele).css("height", (windowHeight - isResetH) + "px").addClass('overflowY');
    if (IsResetW !== null)
        $(ele).css("width", (windowWidth - IsResetW) + "px");
}
 

呼叫方式：

 $(document).ready(function () {
 resizeEle($('div:first'), 80, null);//預設自適應，距螢幕底部80px
 $(window).resize(function () { resizeEle($('div:first'), 80, null); });//換屏自適應
});
