“无法取得财产价值:物体无效或未界定”,同时向独立实体发送文字
原标题:"Unable to get value of the property appendChild : object is null or undefined" while appending script to IE

当我试图将以下文字传给独立实体时,我发现这一错误:

“错误:不能取得财产价值:物体无效或未界定”

该公司在 Chrome进行罚款,但在对E9进行测试时,这种情况发生。 谁能告诉我错误是什么?

  // create script in document
    var fbScript = document.createElement("script");
    fbScript.type = "text/javascript";

    // make script source the facebook plugin
    fbScript.src = "http://connect.facebook.net/en_US/all.js#xfbml=1";



    // append script to appropriate tab
    document.getElementById( Tab  + tab_counter).appendChild(fbScript);
最佳回答

如果在装满超文本的所有部分之前,您的javascript代码就会出现这种情况。 要求将该守则置于功能之中,并用上载活动加以焚烧。 或利用更贵的舱载荷活动。 情况就是如此。

$().ready(function () {
    var fbScript = document.createElement("script");
    fbScript.type = "text/javascript";

    // Make script source the facebook plugin
    fbScript.src = "http://connect.facebook.net/en_US/all.js#xfbml=1";

    // Append script to appropriate tab
    document.getElementById("Tab" + tab_counter).appendChild(fbScript);

});
