本文实例讲述了asp.net实现中英文多域名检测的方法。，具体如下：
第一步：在前台页面中写入js代码和相关控件
/****写入js代码****/
<%-- 域名检测 --%>
<script type="text/javascript">
//判断输入的是否为中文域名
function IsChDomain(domainStr)
{
var flag = false;
var compStr = "ABCDEFGHIGKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz-_0123456789";
var domainLength = domainStr.length;//判断字符长度
for(var i = 0;i < domainLength;i++)
{
var temp = domainStr.charCodeAt(i);
if(temp >= 10000)//含有字符编码大于10000的字符判断为中文，不太严格
{
flag=true;
}
else
{
var temp2 = compStr.indexOf(domainStr.charAt(i));
if(temp2 == -1)
{
flag = false;
break;
}
}
}
return flag;
}
//判断输入的是否为英文域名
function IsEnDomain(domainStr)
{
var flag = false;
var compStr = "ABCDEFGHIGKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz-_0123456789";
var domainLength = domainStr.length;
for(var i = 0;i<domainLength;i++)
{
if(compStr.indexOf(domainStr.charAt(i)) == -1)
{
flag = false;
break;
}
else
{
flag = true;
}
}
return flag;
}
//中国等不能注册英文域名,把相应的CheckBox的disabled属性设置为true，
function Trim(domainStr)
{
return domainStr.replace(/(^s*)|(s*$)/g, "");
}
//验证域名是哪一类型的
function checkDomainType()
{
var domainName = document.getElementById("txtDomainName").value;
domainName = Trim(domainName);//去掉输入的特殊符号
if(IsChDomain(domainName))//调用中文域名----------验证方法
{
setCheckBox(true);
}
else if(IsEnDomain(domainName))//调用英文域名-----验证方法
{
setCheckBox(false);
}
}
//为CheckBox复选框的Checked属性赋值
function setCheckBox(flag)
{
document.getElementById("chkcom").disabled = flag;
document.getElementById("chknet").disabled = flag;
document.getElementById("chkorg").disabled = flag;
document.getElementById("chkorgcn").disabled = flag;
document.getElementById("chkcn").disabled = flag;
document.getElementById("chkcomcn").disabled = flag;
document.getElementById("chknetcn").disabled = flag;
document.getElementById("chkgovcn").disabled = flag;
document.getElementById("chkcouk").disabled = flag;
document.getElementById("chkbiz").disabled = flag;
document.getElementById("chkcc").disabled = flag;
document.getElementById("chktv").disabled = flag;
document.getElementById("chkinfo").disabled = flag;
document.getElementById("chkchina").disabled = !flag;
document.getElementById("chkcompany").disabled = !flag;
document.getElementById("chknetwork").disabled = !flag;
document.getElementById("chkorguk").disabled = flag;
document.getElementById("chkus").disabled = flag;
document.getElementById("chkmeuk").disabled = flag;
document.getElementById("chkltduk").disabled = flag;
}
//检查输入的字符规范
// function checkValue()
// {
// if(document.getElementById("txtDomainName").value=='')
// {
// alert('请输入域名！');
// return false;
// }
// if(document.getElementById("txtDomainName").value.length >= 60)
// {
// alert('域名长度不能超过60个字符！');
// return false;
// }
// for(var i = 0;i < document.getElementById("txtDomainName").value.length;i++)
// {
// if(document.getElementById("txtDomainName").value.charAt(i) == ' ')
// {
// alert('域名中不能含有空格！');
// return false;
// break;
// }
// }
// }
</script>
