html导入独立的js文件出错,无法调用function,求教!
js文件代码如下:
<script type="text/javascript">
var email;
var bemail="0"; // boolean value to check correctness
... ... // other parameters
function chkEmail(email){ // use AJax for dynamic checking
     this.email=email;
     var xmlhttp;
     if (window.XMLHttpRequest) {
         xmlhttp=new XMLHttpRequest();
     }
     else {
         xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
     }
     xmlhttp.onreadystatechange=function() {  
         if (xmlhttp.readyState==4 && xmlhttp.status==200) {
             document.getElementById("email").innerHTML=xmlhttp.responseText;
         }
     }
     if (/^\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$/.test(this.email)){ // regular expression checking
         bemail="1"; // to tell the web page the input is in right format
         xmlhttp.open("GET","chkemail.jsp?email="+email,true); xmlhttp.send();
     }
     else{
         bemail="0"; // to tell the web page the input is in wrong format
         xmlhttp.open("GET","chkemail.html",true); xmlhttp.send();
     }
}
</script>
js文件与html文件放在同一文件夹中,html中部分代码如下:
<head>
... ...
<script type="txt/javascript" src="PrivateRegistration.js"></script>
</head>
<body>
... ...
<form name="form1" onSubmit="return chkform();" method="post" action="connectDataBase.jsp">
<table width="600" cellpadding="2" cellspacing="2" align="center" style="margin-left:60px">
     <tr>
         <td width="130"><span class="style1">* </span>Email</td>
         <td><input size=40 name="txtEmail" type="text" onKeyUp="chkEmail(this.value)" onBlur="chkEmail(this.value)"></td>
         <td><div id="email"></div></td>
     </tr>
... ...
<body>
现在js文件报错(dreamweaver cs5报错),没有任何提示。
只晓得是
     this.email=email;
这一行有问题(第一个function中的第一行),删掉之后又跳到下一行,删掉这个function之后跳到下一个function的第一行,如此循环
这样写有什么不对么?请各路大牛指教。
------解决方案--------------------代码加上高亮很难吗?
