校验银行卡号
1、先引入jquery.js
2、接着引入luhmCheck.js //银行卡号Luhm校验
3、看下面的案例：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>无标题页</title>
<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript" src="js/luhmCheck.js"></script>
</head>
<body>
<input type="text" id="t_bankno" />
<input type="button" id="btnCheck" value="check" onclick="CheckBankNo($('#t_bankno'));" />
<span id="banknoInfo">
</body>
</html> 下面是js
<script type="text/javascript"> function CheckBankNo(t_bankno) {
var bankno = $.trim(t_bankno.val());
if(bankno == "") {
$("#banknoInfo").html("请填写银行卡号");
return false;
}
if(bankno.length < 16 || bankno.length > 19) {
$("#banknoInfo").html("银行卡号长度必须在16到19之间");
return false;
}
var num = /^\d*$/; //全数字
if(!num.exec(bankno)) {
$("#banknoInfo").html("银行卡号必须全为数字");
return false;
}
//开头6位
var strBin = "10,18,30,35,37,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,58,60,62,65,68,69,84,87,88,94,95,98,99";
if(strBin.indexOf(bankno.substring(0, 2)) == -1) {
$("#banknoInfo").html("银行卡号开头6位不符合规范");
return false;
}
//Luhm校验（新）
if(!luhmCheck(bankno))
return false;
$("#banknoInfo").html("验证通过!");
return true;
}
