根据身份证号或社会信用代码判断输入值是否正确

如下:

 / //身份证号校验
    function isIdCardNo(num) {
        num = num.toUpperCase();//身份证号码为15位或者18位,15位时全为数字,18位前17位为数字,最后一位是校验位,可能为数字或字符X。
        if (!(/(^\d{15}$)|(^\d{17}([0-9]|X)$)/.test(num))) {
            alert('输入的身份证号长度不对,或者号码不符合规定!\n15位号码应全为数字,18位号码末位可以为数字或X。');
            //alert('身份证号长度不正确或不符合规定!');
            return false;
        } 
        //验证前2位,城市符合
        var aCity={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"};
        if(aCity[parseInt(num.substr(0,2))]==null){
            alert('身份证号不正确或不符合规定!');
            return false;
        }
        //alert('城市:'+aCity[parseInt(num.substr(0,2))]);
        
        //下面分别分析出生日期和校验位
        var len, re; len = num.length;
