JS 动态创—IV(IE8没问题)Google chrome提示：Uncaught TypeError: Illegal invocation
部分代码如下：

提示错误位置为：var backDiv = cDiv("div");
弹出提示Test1没有弹出Test2，想问下这是Google浏览器不支持还是有错误？应该怎么改？谢谢

 function setChild(div,kid)
 {
  //可否移动、调整
  var isMove = document.getElementById("isMove").checked;
  var isResize = document.getElementById("isResize").checked;
  
  //底色
  var cDiv = document.createElement;
alert('Test1');
  var backDiv = cDiv("div");
alert('Test2');
  backDiv.style.cssText = "left: 0px; top: 0px; width: 100%; height: 100%; background-color: #F5F5F5;";
  div.appendChild(backDiv);
  
  //标题
  var topDiv = cDiv("div");
  topDiv.style.cssText = "left: 2px; top: 2px; width: 100%; height: 30px; position: absolute; background-color: #FF6699; vertical-align: middle; z-index: 5";
  if (isMove)
  {
   topDiv.style.cursor = "move";
   topDiv.setAttribute("onmousedown", function(){setMove(this)});
  }
  else
  {
   topDiv.style.cursor = "default";
  }
  topDiv.innerHTML = "<span style='top: 5px; left:5px; font-size: 20px; font-weight: bold; color: #102548; position: relative;' onselectstart='return false'>聊天</span>";
  div.appendChild(topDiv);

}

[解决办法]
var cDiv = document.createElement;
alert('Test1');
var backDiv = cDiv("div");
alert('Test2');

createElement是个方法，
backDiv = document.createElement("div");
