Question

I need a field validator which does not allow to user to move to the next field if there is an error. I tried the asp validator and jquery validator which allows to move to the next field.

Thanks,

Answer 1

$('.class').focusout(function(){
    if (!isValid($(this).value)){
        $(this).focus();
    } 
});


function isValid(inp){
    return inp !== undefined && inp.length !== 0;
}
