我做了一个无刷新验证用户名的页面，运行正常，但是在tt浏览器下，提示有错误：
行: 126
字符: 3
错误: 类型不匹配
代码: 0
URL: http://localhost/test.html
代码如下（红色是出错部分）：
<script type="text/javascript" language="javascript">
var profile_username_toolong = '对不起，您的用户名超过 15 个字符，请输入一个较短的用户名。';
var profile_username_tooshort = '对不起，您输入的用户名小于4个字符, 请输入一个较长的用户名。';
var profile_username_illegal = '用户名包含敏感字符或被系统屏蔽，注意用户名只能使用英文和数字，请重新填写。';
var profile_username_offlien = '无法连接到数据库，请刷新页面后从新填写。';
var profile_username_used = '用户名已经被使用，请更换。';
var lastseccode = lastsecanswer = lastusername = lastpassword = lastemail = '';
function trim(str) {
return str.replace(/^\s*(.*?)[\s\n]*$/g, '$1');
}
function warning(obj, msg) {
if((ton = obj.id.substr(5, obj.id.length)) != 'password2') {
document.getElementById(ton).select();
}
obj.style.display = '';
obj.innerHTML = '<img src="images/check_error.gif" width="13" height="13"> '+ msg;
obj.className = "warning";
}
function right(obj, msg) {
if((ton = obj.id.substr(5, obj.id.length)) != 'password2') {
document.getElementById(ton).select();
}
obj.style.display = '';
obj.innerHTML = '<img src="images/blue/check_right.gif" width="13" height="13">';
obj.className = "right";
}
function chkacc(){
var username = document.getElementById("username").value;
username = trim(username);
alert("checkusername.asp?username="+username);
}
function checkunindb(username,cu){
var getrs= new ActiveXObject("Microsoft.XMLHTTP");
getrs.open("post","checkusername.asp?username="+username,false);
getrs.send();
getrs.onreadystatechange=statechange(getrs)
}
function statechange(getrs,cu){
if (getrs.readyState == 4){
if(getrs.responseText==""){warning(cu, profile_username_offlien);alert("empty");return;}
else if(trim(getrs.responseText)=="no"){warning(cu, profile_username_used);alert(getrs.responseText);return;}
else if(trim(getrs.responseText)=="yes"){right(cu, 'ok');alert(getrs.responseText);return;}
}else{alert("getrs.readyState"+getrs.readyState);alert("getrs.status"+getrs.status);}}
function checkusername() {
var username = document.getElementById("username").value;
username = trim(username);
if(username == lastusername) {
return;
} else {
lastusername = username;
}
var cu = document.getElementById("checkusername");
var unlen = username.replace(/[^\x00-\xff]/g, "**").length;
if (/^[a-zA-Z0-9_]+$/.test(username)){
if(unlen < 4 || unlen > 15) {
warning(cu, unlen < 4 ? profile_username_tooshort : profile_username_toolong);
return;
}else{
var getrs= new ActiveXObject("Microsoft.XMLHTTP");
getrs.open("post","checkusername.asp?username="+username,false);
getrs.send();
[color=FF0000]getrs.onreadystatechange=statechange(getrs,cu)[/color]
}
}else{
warning(cu, profile_username_illegal);
return;
}
}
</script>

页面运行正常，功能都完好，但是不知道这个错误是怎么回事，心里不踏实，第一次接触javascript和无刷新，大家帮忙看看，谢谢了。
