'null' 不是对象 - 三星智能电视 3d

Question

我有以下将三星智能电视切换到 3d 的代码mode.but它在控制台上显示错误。

TypeError : 'null' is not an object (Evaluating 'SefPlugin.Open')

Main.onLoad = function()
{

    this.enableKeys();
    widgetAPI.sendReadyEvent();
    var SefPlugin = document.getElementById("plugin");
    SefPlugin.Open('Screen', '1.003', 'Screen');
    console.log(SefPlugin.Execute("Get3DEffectMode"));
    SefPlugin.Execute("Set3DEffectMode", MODE_3D_EFFECT_FROM_2D_TO_3D);


};

Answer 1

使用名称属性访问对象元素。

...
 <object id="plugin" name="kekolama" classid="clsid:SAMSUNG-INFOLINK-SEF" style="width:0px; height:0px;"></object>
...

和

var SefPlugin = document.kekolama;
