先说明，这个办法只限于iframe中的子页面也是本地页面（不能引用外网页面）

======方法=====
第一步 js部分

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