js验证输入是否为手机号码或电话号码示例

复制代码 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: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>
