Question

所以我试图在Facebook上托管的Unity应用程序下面放一个横幅。我有以下代码用于在Facebook画布上的应用程序上方注入html元素，取自https://developers.facebook.com/docs/unity/reference/current/CUI/

string injection =
  "var headerElement = document.createElement('div');" +
  "headerElement.textContent = ('Check out our other great games: ...');" +
  "var body = document.getElementsByTagName('body')[0];" +
  "var insertionPoint = body.children[0]; " +
  "body.insertBefore(headerElement, insertionPoint);";
Application.ExternalEval(injection);

我如何在Facebook应用程序下显示这些元素？

Answer 1

这是我的最终解决方案，考虑了不同的浏览器

string injection = "if(navigator.userAgent.indexOf(\"Firefox\") >= 0){;" +

            "var headerElement = document.createElement('div');" +
            "headerElement.innerHTML = '<img src=\"URLTOSOURCE" style=\"width: 100%; text-align: center\" />';" +
            "var body = document.getElementsByTagName('body')[0];" +
            "var insertionPoint = body.lastChild;" +
            "body.insertBefore(headerElement, insertionPoint);" +

            "}else{;" +

            "var headerElement = document.createElement('div');" +
            "headerElement.innerHTML = '<img src=\"URLTOSOURCE" />';" +
            "var body = document.getElementsByTagName('body')[0];" +
            "var insertionPoint = body.children[0]; " +
            "var unityPlayer = document.getElementById('unityPlayerEmbed');" + 
            "unityPlayer.parentNode.insertBefore(headerElement, unityPlayer.nextSibling);" +
            "var embedTag = unityPlayer.getElementsByTagName('embed');" + 
            "embedTag[0].setAttribute('style','display:block;width:1200px;height:600px');" +

            "};";

    Application.ExternalEval(injection);

Answer 2

只需替换

行

"var insertionPoint = body.children[0]; "

的

"var insertionPoint = body.lastChild;"
