关于移除节点的IE和Firefox的兼容问题

function FunNode(obj)
 {
  var objNode = document.getElementById("NodeID");
  if(objNode!=null)
  {
   if(obj.checked)
   {
    var newNode = document.createElement("div");
        newNode.id = "divId";
    var newNodeText = document.createTextNode("Test Child");
        newNode.appendChild(newNodeText);
        objNode.parentNode.appendChild(newNode);
    }
    else
    {
      var n = document.getElementById("divId");
      var wN =document.createTextNode("");
      if(n!=null)
      {
        n.parentNode.replaceChild(wN,n);
      }
    }
  }
 }

使用replaceChild()函数代替removeChild()来实现移除node.

n.parentNode.replaceChild(wN,n);
