I have create a custom validation to check if the user have select one or more items on select2 field with multiselect option, if user didn't have select nothing the validation is not pass.
I have 2 problems:
custom function is call only when I call validator('validate') but not when select2 is unfocus;
when call validator('validate') custom function is call but the class "has-error" is not added to form group so the form is submit.
My JS code:
$('#saveinvoice').validator({
custom: {
'customers': function($el) {
if ($el.select2('data').length==0) {
return "Select one or more customers!";
}
}
}
});
function submitInvoiceData(){
if ($('#saveinvoice').validator('validate').has('.has-error').length == 0) {
...
document.getElementById('saveinvoice').submit();
};
}
