ajax form validation in laravel 5 - php

Question

I am new in laravel and need help.
These are the values I'm getting via ajax, all values are to be stored in db, but how do I validate[check] if there are existing values or not before submitting a form using ajax?
$("#submit").click(function(e){
e.preventDefault();
var url = "{!! URL::to('/') !!}";
var id="{!! #$department->id !!}";
var token = "{!! csrf_token() !!}";
var customer_id = $("#customer_id").val();
var visiting_address1 = $("#visiting_address1").val();
var department_id = $("#department_id").val();
// AJAX Code To Submit Form.
$.ajax({
type: "POST",
url: url+"/customer/"+customer_id+"/popup_store",
data: { '_token':token, 'rest':'true', 'customer_id':$("#customer_id").val(), 'main_address':$("#main_address").val(),'visiting_city':$("#visiting_city").val(),'visiting_address':$("#visiting_address1").val(),'visiting_zip':$("#visiting_zip").val()},
async : false,
success : function(data) {
if(data == "success")
{
$("#addrecords").modal('hide');
}
else
alert(data);
}
});
});

First of all define you Jquery validation for you form like this:
$("#myForm").validate({
// Specify the validation rules
rules: {
name: "required",
},
// Specify the validation error messages
messages: {
name: "Please enter name",
},
submitHandler: function (form) {
// leave it blank here.
}
});
And then in your click button of submit button, write if condition to check validations:
$("#submit").click(function (e) {
if ($('#myForm').valid()) {
// your Ajax Call Code
} else {
return false;
}
});
