强悍的身份验证和银行卡验证，不只是正则哦

• 银行卡验证

/**
 * 银行卡验证
 * @param {*string} str
 */
function isBankCard(str) {
    var regex = /^(998801|998802|622525|622526|435744|435745|483536|528020|526855|622156|622155|356869|531659|622157|627066|627067|627068|627069)\d{10}$/;
    if (regex.test(str)) {
        return true;
    }
    return false;
}

• 身份证验证

function isIdCard (idcard) {
    // 1 "验证通过!",0 //身份证号码校验错误

    var area = { 11: "北京",12: "天津",13: "河北",14: "山西",15: "内蒙古",21: "辽宁",22: "吉林",23: "黑龙江",31: "上海",32: "江苏",33: "浙江",34: "安徽",35: "福建",36: "江西",37: "山东",41: "河南",42: "湖北",43: "湖南",44: "广东",45: "广西",46: "海南",50: "重庆",51: "四川",52: "贵州",53: "云南",54: "西藏",61: "陕西",62: "甘肃",63: "青海",64: "宁夏",65: "新疆",71: "台湾",81: "香港",82: "澳门",91: "国外" }
