在MsIE中检测Pdf阅读器

当点击该IFrame中的链接时,我使用IFrame查看Pdf文档。但是,在没有阅读器的计算机上,链接将提示下载。有没有办法,相同的链接可以提示用户在检测到没有读卡器时下载阅读器?我以为我在某个地方见过这个。谢谢!

这在IE中适用于我:

<script>
var p;
try {
p = new ActiveXObject('AcroExch.Document');
}
catch (e) {
// active x object could not be created
document.write('doesnt look like the PDF plugin is installed...');
}
if (p) {
    document.write('does look like the pdf plugin is installed!');
}
</script>

Found it here. ..但已修改为删除“endif”

我知道这个问题已经得到了解答,但我最近不得不构建一个能够检测不同浏览器中PDF插件存在的功能。这就是我得到的。希望如果有帮助。

function hasPdfPlugin() {   
//detect in mimeTypes array
if (navigator.mimeTypes != null && navigator.mimeTypes.length > 0) {        
    for (i = 0; i < navigator.mimeTypes.length; i++) {
        var mtype = navigator.mimeTypes[i];
        if(mtype.type == "application/pdf" && mtype.enabledPlugin)
            return true;
    }
}

//detect in plugins array
if (navigator.plugins != null && navigator.plugins.length > 0) {
    for (i = 0; i < navigator.plugins.length; i++) {
        var plugin = navigator.plugins[i];
        if (plugin.name.indexOf("Adobe Acrobat") > -1
                || plugin.name.indexOf("Adobe Reader") > -1) {
            return true;
        }

    }
} 
// detect IE plugin
if (window.ActiveXObject) {
    // check for presence of newer object       
    try {
        var oAcro7 = new ActiveXObject('AcroPDF.PDF.1');
        if (oAcro7) {
            return true;
        }
    } catch (e) {
    }

    // iterate through version and attempt to create object 
    for (x = 1; x < 10; x++) {
        try {
            var oAcro = eval("new ActiveXObject('PDF.PdfCtrl." + x + "');");
            if (oAcro) {
                return true;
            }
        } catch (e) {
        }
    }

    // check if you can create a generic acrobat document
    try {
        var p = new ActiveXObject('AcroExch.Document');
        if (p) {
            return true;
        }
    } catch (e) {
    }

}

// Can't detect in all other cases
return false;
}

在JavaScript中,您可以执行以下操作:

var adobePdfObject = new ActiveXObject("theAdobePdfCOMObject");

然后捕获失败错误或adobePdfObject的返回值?
