Hi, how can I validate a field with this js code?.
function checkRut(rut) {
    // Despejar Puntos
    var valor = rut.value.replace('.','');
    // Despejar Guión
    valor = valor.replace('-','');
    // Aislar Cuerpo y Dígito Verificador
    cuerpo = valor.slice(0,-1);
    dv = valor.slice(-1).toUpperCase();
    // Formatear RUN
    rut.value = cuerpo + '-'+ dv
    // Si no cumple con el mínimo ej. (n.nnn.nnn)
    if(cuerpo.length < 7) { rut.setCustomValidity("RUT Incompleto"); return false;}
    // Calcular Dígito Verificador
    suma = 0;
    multiplo = 2;
    // Para cada dígito del Cuerpo
    for(i=1;i<=cuerpo.length;i++) {
        // Obtener su Producto con el Múltiplo Correspondiente
        index = multiplo * valor.charAt(cuerpo.length - i);
        // Sumar al Contador General
        suma = suma + index;
        // Consolidar Múltiplo dentro del rango [2,7]
        if(multiplo < 7) { multiplo = multiplo + 1; } else { multiplo = 2; }
    // Calcular Dígito Verificador en base al Módulo 11
    dvEsperado = 11 - (suma % 11);
    // Casos Especiales (0 y K)
    dv = (dv == 'K')?10:dv;
    dv = (dv == 0)?11:dv;
    // Validar que el Cuerpo coincide con su Dígito Verificador
    if(dvEsperado != dv) { rut.setCustomValidity("RUT Inválido"); return false; }
    // Si todo sale bien, eliminar errores (decretar que es válido)

the visitors have to complete a field, and the code validate that id is correct, this id is like a DNI, unique number, so, this code validate that the DNI is correct.

t I've tried to put advanced options of element but i can't get work.

I need to check deeply your code

I have question

that 'Id' whether it number has specified format or it is the normal numeric number?

t I've tried to put advanced options of element but i can't get work.

For validation for each 'element' should use in the properties of the element, section 'Validation' you have detail explanation on the link below:
