Delete an item created dynamically with jquery

Navigation
3

I have a form and I want to delete the elements created in each time a new element is added dynamically using jQuery Validation Plugin v1.16 

// only for demo purposes
$.validator.setDefaults({
    submitHandler: function() {
        //alert("submitted!");
        console.log("submitted!");
        var form_action =  $("body").find("#orderform").attr("action"); 
        var data = $("body").find("#orderform").serialize(); 
        console.log(data); 
        console.log(form_action); 
    }
});


$.validator.messages.max = jQuery.validator.format("El total no debe superar los {0}!");

$.validator.addMethod("quantity", function(value, element) {
    return !this.optional(element) && !this.optional($(element).parent().prev().children("select")[0]);
}, "Rellene todos los campos de este item.");

$().ready(function() {
    $("#orderform").validate({
        rules:{
          fecha:{
            required: true,
            dateISO: true
          }
        },
        debug:true,
        errorPlacement: function(error, element) {
            error.appendTo(element.parent().next());
        },
        highlight: function(element, errorClass) {
            $(element).addClass(errorClass).parent().prev().children("select").addClass(errorClass);
        }
    });

    var template = jQuery.validator.format($.trim($("#template").val()));

    function addRow() {
        $(template(i++)).appendTo("#orderitems tbody");
    }

    var i = 1;
    // start with one row
    addRow();
    
    // add more rows on click
    $("#add").click(addRow);

    // check keyup on quantity inputs to update totals field
    $("#orderform").on("keyup", "input.quantity", function(event) {
        var totals = 0+100;
        $("#orderitems input.quantity").each(function() {
            totals += +this.value;
        });
        $("#totals").attr("value", totals).valid();
    });
});

I saw your example and added the new elements to an element called 'employeeList', so with jquery you can tell that element stays empty:

$ ('# employeeList') // so you select the element that contains the added elements

and with empty () you leave it empty

Try this by clicking on your rest button: $('#employeeList').empty()

and if you only want to delete the last one: $('#employeeList').children().last().remove()

If you want to be able to delete each element added individually, just add this to your code js: 

<a onclick="$(this).parent().parent().remove()" > Borrar </a>

and it would be like that

  

<script type="text/html" id="addChild"> <div class="form-group"> <label class="col-md-4 control-label" for="textinput">Employee Name </label> <div class="col-md-4"> <input id="FirstName-{0}" name="FirstName-{0}" type="text" placeholder="Enter Employee Name" class="netEmp form-control input-md "> <a onclick="$(this).parent().parent().remove()" > Borrar </a> </div> </div> </script>
