在所以頁面的共用js文件后面添加如下代碼：

function processLowerIENavigate()
{
??var isIE = document.all ? 1 : 0;
??if (isIE == 1)
??{
????if(navigator.userAgent.indexOf("MSIE7.0") > 0 || navigator.userAgent.indexOf("MSIE 8.0") > 0)
????{ ?
??// ?var doc=document;?
??????var link=document_createElement_x_x_x("link");
??????link.setAttribute("rel", "stylesheet");
??????link.setAttribute("type", "text/css");
??????link.setAttribute("id", "size-stylesheet");
??????link.setAttribute("href", "");
??
??????var heads = document.getElementsByTagName_r("head");
??????if(heads.length)
????????heads[0].a(link);
??????else
????????document.documentElement.a(link);

??????document.write("
??????document.write("
??
????}
??}?
}
var lowerIE8 = processLowerIENavigate();

media_screen.js文件內容如下，直接從網上copy：
function adjustStyle(width) {
??width = parseInt(width);
??if (width < 902) {
//alert("<900");
//alert(width);
????$("#size-stylesheet").attr("href", "navigateLowerIE8.css");
??} else {
???// alert(">900");
?//alert(width);
????$("#size-stylesheet").attr("href", "");?
??}
}

$(function() {
??adjustStyle($(this).width());
??$(window).resize(function() {
????adjustStyle($(this).width());
??});
});
