When I try to use jQuery validation rules depends as follows:
<script>
$('#sign-up-form form').validate({
rules: {
state: "required",
school: {
depends: function(element) {
return $("#id_school_id").val().length;
}
}
}
});
</script>
Each time the depends part of the rule runs I get Uncaught TypeError: Cannot read property 'call' of undefined
The id that I'm checking is there (#id_school_id). I'm using jquery.validation.js v 1.11.1
I misunderstood depends to be a rule method. You need to apply its value to a rule method. So, for example
$('#sign-up-form form').validate({
rules: {
state: "required",
school: {
required: {
depends: function(element) {
return $("#id_school_id").val().length;
}
}
}
},
messages: {
school: "Please choose a valid school name from the choices presented"
}
});
</script>
Whether the field 'school' is required depends on the field 'school_id' having a length.
