我有以下代码来计算来自该站点的灯箱插件的窗口宽度。

     * getPageSize() by quirksmode.com
     *
     * @return Array Return an array with page width, height and window width, height
     */
    function ___getPageSize() {
        var xScroll, yScroll;
        if (window.innerHeight && window.scrollMaxY) {  
            xScroll = window.innerWidth + window.scrollMaxX;
            yScroll = window.innerHeight + window.scrollMaxY;
        } else if (document.body.scrollHeight > document.body.offsetHeight){ // all but Explorer Mac
            xScroll = document.body.scrollWidth;
            yScroll = document.body.scrollHeight;
        } else { // Explorer Mac...would also work in Explorer 6 Strict, Mozilla and Safari
            xScroll = document.body.offsetWidth;
            yScroll = document.body.offsetHeight;
        }
        var windowWidth, windowHeight;
        if (self.innerHeight) { // all except Explorer
            if(document.documentElement.clientWidth){
                windowWidth = document.documentElement.clientWidth; 
            } else {
                windowWidth = self.innerWidth;
            }
            windowHeight = self.innerHeight;
        } else if (document.documentElement && document.documentElement.clientHeight) { // Explorer 6 Strict Mode
            windowWidth = document.documentElement.clientWidth;
            windowHeight = document.documentElement.clientHeight;
        } else if (document.body) { // other Explorers
            windowWidth = document.body.clientWidth;
            windowHeight = document.body.clientHeight;
        }   
        // for small pages with total height less then height of the viewport
        if(yScroll < windowHeight){
            pageHeight = windowHeight;
        } else { 
            pageHeight = yScroll;
        }
        // for small pages with total width less then width of the viewport
        if(xScroll < windowWidth){  
            pageWidth = xScroll;        
        } else {
            pageWidth = windowWidth;
        }
        arrayPageSize = new Array(pageWidth,pageHeight,windowWidth,windowHeight);
        return arrayPageSize;
    };

我注意到在 Internet Explorer 9 中，当我单击图像并激活 Lightbox 插件时，透明的背面覆盖仅覆盖 VIEWABLE 高度而不是整个高度。

在此处输入图像描述

这会产生一个问题，因为如果我有另一个带有修改后的灯箱插件的图像并单击透明覆盖层下方，它会在页面顶部打开另一个空灯箱窗口并且无法关闭。

它在 Chrome 和 Firefox 中运行良好。
