頁面加載后加載和執行腳本？

Question

I am trying to load an external javascript (jquery) via my Firefox addon to a third-party webpage, WebDeveloper addons shows the jquery script syntax getting successfully appended to the head section in "View Generated Source" but the script is not getting executed/ fetched?，我在我的插件中使用以下代碼來加載腳本：

function loadjscssfile(filename, filetype){
if (filetype=="js"){ //if filename is a external JavaScript file
  var fileref=document.createElement('script')
  fileref.setAttribute("type","text/javascript")
  fileref.setAttribute("src", filename)
  fileref.setAttribute('onload', 'firefoxInit()');

}
else if (filetype=="css"){ //if filename is an external CSS file
  var fileref=document.createElement("link")
  fileref.setAttribute("rel", "stylesheet")
  fileref.setAttribute("type", "text/css")
  fileref.setAttribute("href", filename)
}
if (typeof fileref!="undefined")
  document.getElementsByTagName("head")[0].appendChild(fileref)
}

請。 指導如何前進。

您可以在 javascript firefoxInit();末尾添加並刪除onload屬性分配。
