AngularJS - 使用Directive调用Javascript函数

Question

点击视频网址时，我使用以下指令附加html并调用VLC对象

myApp.directive('vlcObject', function ($compile, $rootScope,$timeout) {
    var linker = function (scope, element, attrs) {
        $timeout(function () {
            var vlcPlayerTemplate =
                '<object id="vlc" classid="clsid:9BE31822-FDAD-461B-AD51-BE1D1C159921" class="vlc" codebase="http://downloads.videolan.org/pub/videolan/vlc/latest/win32/axvlc.cab" width="100%" height="100%">' +
                '    <param name="Src" value="SomeUrl"></param>' +
                '    <param name="autoplay" value="true" ></param>' +
                '    <param name="toolbar" value="false"></param>' +
                '    <embed type="application/x-vlc-plugin" name="vlcfirefox" autoplay="yes" toolbar="false" width="100%" height="100%" target="SomeUrl"></embed>' +
            '</object>';
            element.html(vlcPlayerTemplate);
            $compile(element.contents())(scope);
        });        
    };
    return {
        restrict: "E",
        replace: true,
        link: linker
    };
});

通过服务调用指令

this.startVLCPlayerAt = function (pictureboxIndex) {
    angular.element(
        document.querySelector('#StreamingArea' + pictureboxIndex)
    ).append($compile("<vlc-object></vlc-object>")($rootScope));
};`

现在我想要包含/调用JavaScript函数以及指令，所以当点击url时，会发生两件事

1. 1）附加VLC对象HTML
2. 2）调用以下JS功能并创建VLC播放列表并执行 必要的操作

JS功能

function getVLC(name)
{
    if( window.document[name] )
    {
        return window.document[name];
    }
    if( navigator.appName.indexOf("Microsoft Internet") == -1 )
    {
        if( document.embeds && document.embeds[name] )
            return document.embeds[name];
    }
    else
    {
        return document.getElementById(name);
    }
}

function registerVLCEvent(event, handler)
{
    var vlc = getVLC("vlc");

    if( vlc )
    {
        if( vlc.attachEvent )
        {
            // Microsoft
            vlc.attachEvent(event, handler);
        }
        else if( vlc.addEventListener )
        {
            // Mozilla: DOM level 2
            vlc.addEventListener(event, handler, false);
        }
    }
}

function unregisterVLCEvent(event, handler)
{
    var vlc = getVLC("vlc");

    if( vlc )
    {
        if( vlc.detachEvent )
        {
            // Microsoft
            vlc.detachEvent(event, handler);
        }
        else if( vlc.removeEventListener )
        {
            // Mozilla: DOM level 2
            vlc.removeEventListener(event, handler, false);
        }
    }
}

function doGo(targetURL)
{
    var vlc = getVLC("vlc");

    if( vlc )
    {
        vlc.playlist.items.clear();
        var options = [":rtsp-tcp"];
        var itemId = vlc.playlist.add(targetURL,"",options);
        if( itemId != -1 )
        {
            // play MRL
            vlc.playlist.playItem(itemId);
        }
        else
        {
            alert("cannot play at the moment !");
        }
    }
}

随后，当用户点击播放/暂停按钮时，我正在使用以下功能执行相同的操作

<input type="button" id="PlayOrPause" style="width:60px" value="Play" onClick='doPlayOrPause();'>
<input type="button" value="Stop" onClick='doStop();'>

function doPlayOrPause()
    {
        var vlc = getVLC("vlc");
        if( vlc )
        {
            if( vlc.playlist.isPlaying )
                vlc.playlist.togglePause();
            else
                vlc.playlist.play();
        }
    }

    function doStop()
    {
        var vlc = getVLC("vlc");
        if( vlc )
            vlc.playlist.stop();
    }

如何使用指令调用上述JS函数？
