Javascript获得MIME类型支持 [英] Javascript get MIME type support

问题描述

我发现了如何从navigator.mimeTypes获取模仿类型:

I found how to get mimetypes from navigator.mimeTypes:

function GetMimeTypes() {
    var message = "";
    var mimes = navigator.mimeTypes;
    for (var i = 0; i < mimes.length; i++) {
        message += "<b>" + mimes[i].type + "</b> : " + mimes[i].description + "/" + mimes[i].suffixes + "<br />";
    }

    var info = document.getElementById("mime");
    info.innerHTML = message;
}​

，但不会返回类似的类型 text/html，text/css或text/javascript.我发现:自然地，几种MIME类型由浏览器本身处理，例如文本/javascript(JavaScript文件)，文本/css(CSS样式表)，图像/gif(GIF编码图像)，图像/jpegimages，文本/xml(XML文件)和text/html(HTML文件).但是，还有许多其他问题是由插件和检查程序navigator.mimeTypes ["text/html"]！= null处理的，如何获得这些列表?

but it doesn't return types like text/html, text/css or text/javascript. I found: Naturally,several MIME types are handled by the browser itself, such as text/javascript(JavaScript files), text/css (CSS style sheets), image/gif (GIF-encoded images), image/jpegimages),text/xml (XML files), and text/html(HTML files). Many others, however, are handled by plugins and checker navigator.mimeTypes["text/html"] != null, how can i get list of these?

推荐答案

在Google Chrome/Firefox中使用您的代码，我得到:

Using your code in Google Chrome/Firefox I get:

application/vnd.chromium.remoting-viewer : /
pepper-application/x-chromoting : /
application/x-nacl : Native Client Executable/nexe
application/pdf : Portable Document Format/pdf
application/x-google-chrome-print-preview-pdf : Portable Document Format/pdf
application/x-shockwave-flash : Adobe Flash movie/swf
...
etc.

如果您使用的是Internet Explorer，那么很遗憾，不支持navigator.mimeTypes.

If you're using Internet Explorer, then navigator.mimeTypes is not supported unfortunately.

请参见下面的链接，以确认您无法从IE获取模仿类型列表: http://www.howtocreate.co.uk/wrongWithIE/?chapter=navigator .plugins
