在開發中,有時候會涉及到人物身分證登記,那麼怎麼驗證身分證格式是正確的,接下來附上一段JS程式碼驗證身分證格式:
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"} function isCardID(sId){ var iSum=0 ; if(!/^\d{17}(\d|x)$/i.test(sId)) return "你输入的身份证长度或格式错误"; sId=sId.replace(/x$/i,"a"); if(aCity[parseInt(sId.substr(0,2))]==null) return "身份证号格式错误"; sBirthday=sId.substr(6,4)+"-"+Number(sId.substr(10,2))+"-"+Number(sId.substr(12,2)); var d=new Date(sBirthday.replace(/-/g,"/")) ; if(sBirthday!=(d.getFullYear()+"-"+ (d.getMonth()+1) + "-" + d.getDate()))return "身份证号格式错误"; for(var i = 17;i>=0;i --) iSum += (Math.pow(2,i) % 11) * parseInt(sId.charAt(17 - i),11) ; if(iSum%11!=1) return "身份证号格式错误!"; //aCity[parseInt(sId.substr(0,2))]+","+sBirthday+","+(sId.substr(16,1)%2?"男":"女"); //此次还可以判断出输入的身份证号的人性别 return true; }
