我想寻求帮助来解决ASP.Net MVC应用程序中面临的IE浏览器不兼容问题。 该应用程序的页面之一包含一个显示PDF的链接。 在IE8中,该页面显示错误(“ Internet Explorer无法显示此页面”或“空白页面”)。 但是,我可以在Google Chrome,Mozilla Firefox和IE9中访问pdf。

实际上, 我需要在IE8中显示PDF

如果有人以前曾遇到类似问题或有任何解决方案,请您帮助我们解决此问题? 我尝试了几种选择,但无法解决。

的HTML

<div id="pdf1" class="message_details_pdf"></div>

Java脚本代码

 var myPDF = new PDFObject({
            url: 'my_pdf_url',
            pdfOpenParams: {
                view: 'Fit',
                scrollbars: '0',
                toolbar: '0',
                statusbar: '0',
                navpanes: '0'
            }
        }).embed("pdf1");

我遇到了与您类似的问题,但我正在与IE11对抗。 我向pdfobject.js添加了一些代码行来解决我的问题。 我不知道这是否适用于IE8,但我想我的mod可以以某种方式为您提供帮助。

通过在下面的代码中找到不带引号的“ //#”来搜索mod。 希望这可以帮助。

var PDFObject = function (obj)
{
    if (!obj || !obj.url) { return false; }

    var pdfobjectversion = "1.2",
        //Set reasonable defaults
        id = obj.id || false,
        width = obj.width || "100%",
        height = obj.height || "100%",
        pdfOpenParams = obj.pdfOpenParams,
        url,
        pluginTypeFound;
