无法调用方法'toString'ofundefined|我的代码有问题

Cannot call method 'toString' of undefined | There is something wrong with my code?

本文关键字：我的 代码 有问题 ofundefined toString 调用 方法      更新时间：2023-09-26

显然我的脚本是对的，有人能帮我吗？当我看到控制台时，它显示消息Cannot call method 'toString' of undefined。

可能是ID选择器有问题吗？我可以只使用一个函数而不是使用一个进行验证和另一个来运行我的函数吗？

/* ==== CPF Validator ==== */
function validar_cpf(cpf)
{
    regex = /'./g;
    cpf = cpf.toString().replace(regex,'');
    cpf_split = cpf.split('-');
    numero = cpf_split[0];
    dv = cpf_split[1];
    numero_init = numero.toString() + dv.toString();
    if(numero_init.length < 11)
        return false
    var somatorio = 0;
    for(i = 10, n = 0; i >= 2 ; i--, n++){
        m = numero.charAt(n) * i;
        somatorio += m;
    }

    dv1 = somatorio / 11;   
    dv1 = parseInt(dv1);
    resto = somatorio % 11;
    if(resto < 2)
        dv1 = 0;
    else
        dv1 = Math.abs(11 - resto);
    numero += dv1.toString();
    somatorio = 0;
    for(i = 11, n= 0; i >= 2 ; i--, n++ ){
        m = numero.charAt(n) * i;
        somatorio += m;
    }
    resto = somatorio % 11;
    if(resto < 2)
        dv2 = 0;
    else
        dv2 = 11 - resto;
    numero += dv2.toString();
    if(numero == numero_init)
        return true;
    else
        return false;
}

}

我找到了一个解决方案
