Answer 3

的Javascript ::

//to avoid global bashing
(function(){
  var target = document.getElementById('ScriptName'),
    parent = target.parentElement,
    oput = document.createElement('div');
  oput.innerHTML = "<p>Some Content</p>";
  parent.insertBefore(oput, target);
}());

HTML给客户/人::

<script type="text/javascript" id="ScriptName" src="/path/to/ScriptName.js"><script>

ScriptName应该是您脚本的独特内容。
