javascript - 尝试填充 Lync Presence 时在 NPObject 上调用方法时出错

Question

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

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

它在我的电脑上运行良好，但在我尝试在另一台不包含“微软”东西的电脑上运行后，我收到错误“在 NPObject 上调用方法时出错”。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' : 'david@example.com',
        'img' : 'lync_photo/example.png'
    },
    '2' : {
        'name' : 'dennis',
        'sip' : 'dennis@example.com',
        '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 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>";

我应该安装特定的插件还是安装特定的软件到电脑上？

Answer 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的站点。那么它也只能在非 IE 浏览器上工作。我也遇到了类似的问题，当我添加到受信任的站点时，问题就解决了。
