我遇到了与您类似的问题，但我正在与 IE11 作斗争。我在 pdfobject.js 中添加了几行代码来解决我的问题。我不知道这是否适用于 IE8，但我认为我的 mod 可以以某种方式帮助你。
通过在下面的代码中查找不带引号的“//#”来搜索模组。希望这可以帮助。
var PDFObject = function (obj)
{
if (!obj || !obj.url) { return false; }

//Set reasonable defaults
id = obj.id || false,
width = obj.width || "100%",
height = obj.height || "100%",
pdfOpenParams = obj.pdfOpenParams,
url,
pluginTypeFound;
