How to remove options from a selectize dropdown according to a selection from another selectize dropdown?

Question

I am using JavaScript Selectize dropdown. I want to change payment types as per the selection of reseravtion type in my code. Code is as following,

 $(document).ready(function () { $("#reservationType").change(function () { managePaymentTypes(); }); }); var $reservationTypeObj = $('#reservationType').selectize({ sortField: { field: localStorage.getItem("selectizeField"), direction: localStorage.getItem("selectizeDirection") }, dropdownParent: localStorage.getItem("selectizeDropdownParent") }); var $paymentTypeObj = $('#paymentType').selectize({ sortField: { field: localStorage.getItem("selectizeField"), direction: localStorage.getItem("selectizeDirection") }, dropdownParent: localStorage.getItem("selectizeDropdownParent") }); function managePaymentTypes(){ var resType = $('#reservationType :selected').val(); if(resType==202){ //remove option 2 - Salary deduct in selectize. }else if(resType==101) { //remove option 1 - Credit in selectize. }else{ //// } } 

 <label class="col-md-1 control-label firstcol" for="type" style="text-align:left">Reservation Type : </label> <div class="col-md-2" id="reservationTypeDiv" data-toggle="tooltip" data-container="body" data-placement="bottom"> <select class="demo-default selectized" id="reservationType" name="reservationType" tabindex="7" opacity: 1" data-toggle="tooltip" data-container="body" data-placement="bottom"> <% for (int l = 0; l < reservationTypes.size(); l++) { %> <option value="<%=reservationTypes.get(l).getId()%>"><%=reservationTypes.get(l).getDescription()%></option> <% } %> </select> </div> <label class="col-md-1 control-label firstcol" for="payment" style="text-align:left">Payment Type : </label> <div class="col-md-2" data-toggle="tooltip" id="paymentTypeDiv" data-container="body" data-placement="bottom"> <select class="demo-default selectized" id="paymentType" name="paymentType" tabindex="7" opacity: 1" data- toggle="tooltip" data-container="body" data-placement="bottom"> <% for (int l = 0; l < reservationPaymentTypes.size(); l++) { %> <option value="<%=reservationPaymentTypes.get(l).getId()%>"><%=reservationPaymentTypes.get(l).getDescription()%></option> <% } %> </select> </div> 

I have two selectize dropdowns.

1. For reservation type
2. For payement type

Values are getting from database. Reservation types drop-down screenshot , Payment types drop-down screenshot

When reservation type changes I want to change the payment types. Therefore onchange of reservation type I have called a method named managePaymentTypes(). I want to remove Credit payment option when reservation type is Individual(101). And I want to remove Salary deduct option when reservation type is Coporate(202). Individual should be default selection. This is my requirement. Someone please help me to solve this.

I have came up with the following solution.

    $(document).ready(function () {      
<%
    for(SportsCenterReservationPaymentType paymentType : reservationPaymentTypes){
    %>
        paymentTypes.push({id: <%=paymentType.getId()%>, desc: '<%=paymentType.getDescription()%>'});
    <%
    }
    %>
    $("#reservationType").change(function () {           
        loadResourceTable();
        managePaymentTypes();
    });      

});

function managePaymentTypes(){ 
    var resType = $('#reservationType :selected').val();
    $('#paymentType')[0].selectize.clearOptions();

    if(resType==202&& resType!=101){

        $.each(paymentTypes, function (idx, obj) {
            if(obj.id!=333){
              $('#paymentType')[0].selectize.addOption({value:obj.id,text:obj.desc})  
            }
        });
    }

    if(resType==101&&resType!=202){

        $.each(paymentTypes, function (idx, obj) {
            if(obj.id!=222){
              $('#paymentType')[0].selectize.addOption({value:obj.id,text:obj.desc})  
            }
        });
    }

}
