js验证输入是否为手机号码或电话号码示例

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:13916752109或0712-3614072"); 
tel.focus(); 
return false; 
} 
} 
} 
</script> 
<form name="form1" method="post" action="" > 
<input type="text" name="tel" value="13916752109" size="15" /> 
<input type="button" value="测 试" onclick="return chkForm()"/> 
</form>
