Javascript验证输入是否为手机号码或电话号码

Javascript验证输入是否为手机号码或电话号码,代码如下:

<script type=”text/javascript”>
String.prototype.Trim = function() {
var m = this.match(/^\\s*(\\S+(\\s+\\S+)*)\\s*/);
return (m == null) ? “” : m[1];
}

String.prototype.isMobile = function() {
return (/^(?:13\\d|15[89])-?\\d{5}(\\d{3}|\\*{3})/.test(this.Trim()));
}

String.prototype.isTel = function()
{
//”兼容格式: 国家代码(2到3位)-区号(2到3位)-电话号码(7到8位)-分机号(3位)”
//return (/^(([0\\+]\\d{2,3}-)?(0\\d{2,3})-)?(\\d{7,8})(-(\\d{3,}))?/.test(this.Trim()));
return (/^(([0\\+]\\d{2,3}-)?(0\\d{2,3})-)(\\d{7,8})(-(\\d{3,}))?/.test(this.Trim()));
}

function chkForm() {
with(document.form1){
if (tel.value.isMobile()||tel.value.isTel()) {
tel.value = tel.value.Trim();
alert(“您的电话/手机号码是:” + tel.value);
return true;
}
else {
alert(“请输入正确的手机号码或电话号码\\n\\n例如:13888888888或021-8888888″);
tel.focus();
return false;
}
}
}
</script>
<form name=”form1″ method=”post” action=”http://www.dwww.cn” >
<input type=”text” name=”tel” value=”13888888888″ size=”15″ />
