让iframe自适应高度(支持XHTML,支持FF)

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;
              windowHeight = document.body.clientHeight;
      }

      // for small pages with total height less then height of the viewport
      if(yScroll < windowHeight){
              pageHeight = windowHeight;
              y = pageHeight;
      } else {
              pageHeight = yScroll;
              y = pageHeight;
      }

      if(xScroll < windowWidth){
              pageWidth = windowWidth;
      } else {
              pageWidth = xScroll;
      }

      arrayPageSize = new Array(pageWidth,pageHeight,windowWidth,windowHeight)
      return arrayPageSize;
}
这段代码用来获取目标页的参数,包括页面高、宽,屏幕高、宽
function autoHeight(pid) {
      var x = new getSize();
      parent.document.getElementById(pid).height=x[1];
}
这段代码用来实现父页面中iframe的高度自适应

第二步 页面部分


这是父页面的iframe,没什么特别的,和普通的iframe一样,不过要设置好id值,以便子页面的参数调用。


在body中利用onload事件,将自身的高度传给父页面的iframe。

打完收工~本方法在IE6,FF2,XPsp2下顺利通过,FF无报错~
