    getPageSize函数返回一个数组,前两个是整个页面的宽度和高度,后两个是页面窗口的宽度和高度 

    function getPageSize() 

        {
            var xScroll, yScroll;
            
    if (window.innerHeight && window.scrollMaxY)
            {
                xScroll 
    = document.body.scrollWidth;

    = window.innerHeight + window.scrollMaxY;
            } 
            
    else if (document.body.scrollHeight > document.body.offsetHeight) 
            {
                xScroll 
    = document.body.scrollWidth;
                yScroll 
    = document.body.scrollHeight;
