DOM应用时的一个问题?

<script   type   =   "text/javascript ">

<!--

function   makeNode(str){
var   newParagraph   =   document.createElement( "p ");
var   newText   =   document.createTextNode(str);
newParagraph.appendChild(newText);
return   newParagraph;
}

function   appendBefore(nodeId,str){
var   node   =   document.getElementById(nodeId);
var   newNode   =   makeNode(str);

if(node.parentNode)
node.parantNode.insertBefore(newNode,node);
}

  function   insertWidthin(nodeId,str){
var   node   =   document.getElementById(nodeId);
var   newNode   =   makeNode(str);
node.appendChild(newNode);
}

function   appendAfter(nodeId,str){
var   node   =   document.getElementById(nodeId);
var   newNode   =   makeNode(str);

if(){
if(node.nextSibling)     node.parentNode.insertBefore(newNode,node.nextSibling);
else   node.parentNode.appendChild(newNode);
}
}

//-->
</script>
</head>

<body>
<h1> DOM   Insert   and   Append </h1>

<!--script>
                alert( "body   Ok!! ");
</script-->
<hr>
<div   style   = "background-color:#66ff00 ">
<div   id= "innerDiv "   style= "background-color:#ffcc00; "> </div>
</div>

<hr>
   
<form   id   = "form1 "   name   =   "form1 "   action   = "# "   method   = "get ">

<input   type   = "text "   id   = "field1 "   name   =   "field1 ">

<input   type   = "button "   value= "Before "   onclick= "appendBefore( 'innerDiv ',document.form1.field.value); ">

<input   type   = "button "   value= "Middle "   onclick= "insertWithin( 'innerDiv ',document.form1.field.value); ">

<input   type   = "button "   value= "After "   onclick= "appendAfter( 'innerDiv ',document.form1.field.value); ">

</form>

</body>

</html>

我在研究以上代码,可一直找不到为啥它不能正常显示的原因,请高手帮俺分析分析,谢谢!
