哪里错了，求指教（insertBefore相关内容）

<!DOCTYPE HTML>
<html>
<head>

<title>无标题文档</title>
</head>
<body>

<ul id="test"><li>JavaScript</li><li>HTML</li></ul>

<script type="text/javascript">

var otest = document.getElementById("test");
var node;//内容为HTML的标签
var newNode = document.createElement("li");
newNode.innerHTML = "PHP";
var i = 0;
while(otest.childNodes[i]){
         if(otest.childNodes[i].innerHTML == "HTML"){
             node = otest.chhildNodes[i];
             break;
         }
         i++;
}

otest.insertBefore(newNode,node);
</script>
</body>
</html>

已采纳

node = otest.chhildNodes[i];
chhild 多打h 打错字注意检查不要乱挂

while(otest.childNodes[i]){
         if(otest.childNodes[i].innerHTML == "HTML"){
             node = otest.chhildNodes[i];
             break;
         }
         i++;
}
```
otest.childNodes[i].innerHTML == "HTML" 改为otest.childNodes[i].value== "HTML"
```
