用于检测Skype的Javascript？ [英] Javascript to detect Skype?

问题描述

某些Javascript是否可以检测是否安装了Skype？

我问的原因是我想要根据以下内容更改链接的href：如果未安装Skype，请显示一个弹出窗口，说明Skype是什么以及如何安装它，如果已安装，请将链接更改为 skype：my.contact。 name？call 所以点击将开始通话。房地产问题意味着我更愿意只显示一个链接。

The reason I ask is that I'd like to change a link's href based on that: if Skype isn't installed, show a popup explaining what Skype is and how to install it, if it is installed, change the link to skype:my.contact.name?call so the click will start a call. Real estate issues means that I'd prefer to only have one link shown.

推荐答案

感谢大家的答案：来自链接和方法seanb和一些发布，我能够提出一个适用于IE和Firefox的解决方案，所以我想我会发布一个'完整'的答案。这是一个方便的jQuery扩展！

Thanks for the answers everyone: from the links and methods seanb and some posted, I was able to come up with a solution which works for IE and Firefox, so I thought I'd post a 'complete' answer. Here it is as a handy jQuery extension!

jQuery.extend({
    skype : function(failureFunction) {
        var $ = jQuery;

        if ($.browser.safari || $.browser.opera) {
            return true;
        } else if ($.browser.msie) {
            try {
                if (new ActiveXObject("Skype.Detection")) return true;
            } catch(e) { }
        } else {
            if (typeof(navigator.mimeTypes["application/x-skype"]) == "object") {
                return true;
            }
        }
        $('a[href^="skype:"]').click(function() {
            failureFunction();
            return false;
        });
        return false;
    }
});

用法

HTML：

Usage

HTML:

<a href="skype:your.skype.username?call">Call me</a>
<a href="skype:your.skype.username?add">Add me</a>

Javascript：

Javascript:

jQuery(function($) {
    $.skype(function() {
        // this function gets called if they don't have skype.
        alert("Looks like you don't have skype. Bummer.");
    });
});

就是这样！

如果有人使用Safari，Opera或Chrome时，只需让浏览器处理它。

If someone using Safari, Opera or Chrome comes along, it'll just let the browser deal with it.

编辑：重新调整功能以便它只执行检查页面加载时，而不是每次加载页面时。 $。skype 函数现在将返回一个bool，告诉你是否检测到skype 。

edit: rejigged the function so that it only performs the check when the page loads, not each time the page is loaded. The $.skype function will now return a bool telling you if skype was detected or not.
