正则表达式判断手机号的运营商（电信移动联通）

$tel=$('.tel').val().trim();var res=checkMobile($tel);

function checkMobile(telphone){var isChinaMobile = /^((13[4-9])|(15([0-2]|[7-9]))|(18[2|3|4|7|8])|(178)|(147))[\d]{8}$/; //移动var isChinaUnion = /^((13[0-2])|(145)|(15[5-6])|(176)|(18[5-6]))[\d]{8}$/; //联通var isChinaTelcom = /^((133)|(153)|(18[0|1|9])|(177))[\d]{8}$/; //电信var isOtherTelphone = /^170([059])\\d{7}$/;//其他运营商if(telphone.length !== 11){return '未检测到正确的手机号码';}else{if(isChinaMobile.test(telphone)){return '移动';}else if(isChinaUnion.test(telphone)){return '联通';}else if(isChinaTelcom.test(telphone)){return '电信';}else if(isOtherTelphone.test(telphone)){var num = isOtherTelphone.exec(telphone);return '其他运营商';}else{return false;}}}
