私はクロムエクステンションから来る単純なオーバーレイdivを構築しようとしますが、ほとんどの場合動作しますが、次のようなサイトはほとんどないことに気付きました: http://en.wikipedia.org/wiki/Main_Page を追加しようとすると、このエラーが発生しますdiv 。

これは私のコードです:contenet.js:

var s = document.createElement('script');
s.src = chrome.extension.getURL('script_inpage.js');
s.onload = function() {
    s.parentNode.removeChild(s);
};

try{
 console.log("appendChild START");
    (document.head||document.documentElement||document.body).appendChild(s);
 console.log("appendChild DONE");
}catch(e){
  console.log("exception in appendChild");
}

script_inpage.js

try{
    var buttonnode= document.createElement('input');
    buttonnode.setAttribute('type','button');
    buttonnode.setAttribute('id','test_btn');
    buttonnode.setAttribute('value','Test!');


    var div_bottom = document.createElement("div");
    div_bottom.id = "div_bottom";
    div_bottom.style.width = "300px";
    div_bottom.style.height = "20px";
    div_bottom.style.background = "#999";
    div_bottom.style.position="fixed";
    div_bottom.style.bottom="0";
    div_bottom.style.right="0";
    div_bottom.style.zIndex="9999"
    div_bottom.innerHTML = "Hello from div";
    div_bottom.appendChild(buttonnode);
    document.body.appendChild(div_bottom);
}
catch(e){
  console.log("script in page exception in appendChild"+e);
  alert(e);
}
