【问题描述】：

我想使用 javascript 填充 Lync 用户状态，并在下面找到一些好的教程

http://blogs.msdn.com/b/tomholl/archive/2013/03/02/integrate-lync-into-your-intranet-sites-using-the-namectrl-plug-in.aspx

它在我的计算机上运行良好，但在我尝试在另一台不包含“microsoft”的计算机上运行后，我收到错误“NPObject 上的错误调用方法”。我尝试为 firefox 安装 active x 插件，但仍然出现错误 (https://code.google.com/p/ff-activex-host/downloads/list)。

在我的代码下面

<script language="javascript">

var nameCtrl = null;
var lyncUsers = 
    '1' : 
        'name' : 'david',
        'sip' : '[e-mail]',
        'img' : 'lync_photo/example.png'
    ,
    '2' : 
        'name' : 'dennis',
        'sip' : '[e-mail]',
        'img' : 'lync_photo/example.png'
    

;

window.onload=function()
    try 
        if (window.ActiveXObject) 
            nameCtrl = new ActiveXObject("Name.NameCtrl");

         else 
            nameCtrl = CreateNPApiOnWindowsPlugin("application/x-sharepoint-uc");
        
        attachLyncPresenceChangeEvent();
        PopulateUser();
    
    catch (ex) alert(ex.toString()); 
;

function PopulateUser() 
    for (objVal in lyncUsers)  
        var userName = lyncUsers[objVal].sip;
        var userElementId = getId(userName);
        var imagePath = lyncUsers[objVal].img;
        var userSection =  "<div id=\""+userElementId+"\" class=\"user\"";
        userSection += "onmouseover=\"showLyncPresencePopup('"+userName+"', this)\" onmouseout=\"hideLyncPresencePopup()\">";
        userSection += "<img class=\"img_user\"width=\"80px\" height=\"80px\" src=\""+imagePath+"\"  />";
        userSection += "</div>";

        var div = document.getElementById('users');
        div.innerhtml += userSection;
        getStatus(userName);

    


function getStatus(sip)

    if (nameCtrl) 
            nameCtrl.GetStatus(sip, 'users');

我应该在电脑上安装特殊插件还是安装特殊软件？

【问题讨论】：

您可能需要插件源或与发布插件的人交谈以追踪它。你得到的错误是一个通用的错误，除了出现问题之外什么都不告诉你。

【参考方案1】：

您应该将您的站点添加到 Internet Explorer 中的受信任站点。 即使您没有使用 IE 运行您的应用程序，您也应该将该特定站点添加到受信任站点。然后只有它也适用于非 IE 浏览器。我也遇到了类似的问题，当我添加到受信任的站点时，问题得到了解决。
