复制代码 代码如下:

var certCardValid = function(id){

return false;

}

var ai = id.length == 18 ? id.substring(0,17) : id.slice(0,6) + "19" + id.slice(6,16);

Ext.MessageBox.alert("信息提示","身份证除最后一位外，必须为数字。");

return false;

}

var yyyy = ai.slice(6,10);

var mm = ai.slice(10,12)-1;

var dd = ai.slice(12,14);

var d = new Date(yyyy,mm,dd);

var now = new Date();

var year = d.getFullYear();

Ext.MessageBox.alert("信息提示","身份证无效。");

return false;

}

for(var i = 0,ret = 0; i < 17; i++){

ret += ai.charAt(i) * wi[i];

}

ai += arrVerifyCode[ret %= 11];

ai = ai.toUpperCase();

if(id.length == 18 && id != ai){

return false;

}

return true;
