jQuery Validation, multiple form ids for same function

Question

Hi have two forms with the exact same validation rules, but different ids that I'd like to combine into just one function. How can I do that?

var validator = $("#ValidateForm1").validate({
errorPlacement: function(error, element) {
    if ( element.is(":radio") )
        error.appendTo( element.parent().next().next() );
    else if ( element.is(":checkbox") )
        error.appendTo ( element.next() );
    else
        error.appendTo( element.parent().next() );
}       
});

var validator = $("#validateForm2").validate({
errorPlacement: function(error, element) {
    if ( element.is(":radio") )
        error.appendTo( element.parent().next().next() );
    else if ( element.is(":checkbox") )
        error.appendTo ( element.next() );
    else
        error.appendTo( element.parent().next() );
}       
}); 

Answer 1

Make the formId as a variable

var myFormId = "ValidateForm1"; // e.g. get the form id by using javascript

....

var validator = $("#"+ myFormId).validate({
errorPlacement: function(error, element) {
    if ( element.is(":radio") )
        error.appendTo( element.parent().next().next() );
    else if ( element.is(":checkbox") )
        error.appendTo ( element.next() );
    else
        error.appendTo( element.parent().next() );
}       
});

If you don't need the validator variable (which you're re-defining, so it appears you don't), just use a multiple selector:

$("#validateForm1, #validateForm2").validate({
  errorPlacement: function(error, element) {
    if ( element.is(":radio") )
        error.appendTo( element.parent().next().next() );
    else if ( element.is(":checkbox") )
        error.appendTo ( element.next() );
    else
        error.appendTo( element.parent().next() );
  }       
});

Or, if you have a lot of forms like this, just give them a class and like this:

<form id="validateForm1" class="myFormClass"></form>
<form id="validateForm2" class="myFormClass"></form>
....
<form id="validateFormX" class="myFormClass"></form>

And a selector like this:

$(".myFormClass").validate({
