js regular expression to verify phone number mobile phone number

The following are several regular expressions about js verification of phone numbers and mobile phone numbers. I have collected them from the Internet, but they are all high-quality products and are professionally designed to verify mobile phone numbers and phone numbers.

function checkPhone(phone)
{
//验证电话号码手机号码，包含153，159号段
if (phone==""){
alert("电话号码不能为空!");
return false;
}
if (phone != ""){
var p1 = /^(([0+]d{2,3}-)?(0d{2,3})-)?(d{7,8})(-(d{3,}))?$/;
var me = false;
if (p1.test(phone)) me=true;
if (!me){
//alert('对不起，www.jb51.net您输入的电话号码有错误。区号和电话号码之间请用-分割');
return false;
}
}
return true;
}

Mobile number verification

String.prototype.isTel = function()
{
//"兼容格式: 国家代码jb51.net(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}-)?(0d{2,3})-)?(d{7,8})(-(d{3,}))?$/.test(this.Trim()));
return (/^(([0+]d{2,3}-)?(0d{2,3})-)(d{7,8})(-(d{3,}))?$/.test(this.Trim()));
}
//验证手机号
String.prototype.isMobile = function() {
return (/^(?:13d|15[89])-?d{5}(d{3}|*{3})$/.test(this.Trim()));
}

Phone number verification

function CheckNum(){//电话验证
var InputValue=document.gsjbxxBean.dh.value;
var reg=/^([0-9]|[-])+$/g ;
var isValid
isValid=reg.exec(InputValue)
if (!isValid) {
return false
}
return true
}

Check phone number

function isTel(str){
var reg=/^([0-9][-])+$/g ;
if(str.length<7 str.length>18){
return false;
}
else{
return reg.exec(str);
}
}
