如何动态添加和删除多个字段？

Question

Is there an easier way in JQuery to dynamically add and remove fields for more than one field within the same form? I have two form elements in the same form that I'd like to have the ability to add and remove blank fields to.

<div class="col-sm-3">
    Email<g:field type="email" name="Email" class="form-control" required="" value="" aria-labelledby="Email-label"/>
</div>
<div class="col-sm-2">  
    Fax<g:field type="tel" name="Fax" class="form-control" required="true" value="" aria-labelledby="Fax-label"/>
</div>

I have cobbled together this javascript piece from several different places and it works just fine for the first field, but when I try to duplicate it for the second one it doesn't work.

$(document).ready(function(){
    $("#add").click(function (e) {
        $("#submitterEmail").append('<div><input type="text" name="submitterEmail[]"><button class="delete">Delete</button></div>');
    });

$("body").on("click", ".delete", function (e) {
    $(this).parent("div").remove();
});
});

Here's the JavaScript based on the HTML you have:

$(document).ready(function(){
    $("#add").on("click", function(){
        $("#container").append(
            "<div class='col-sm-3'><g:field>Another field <button class='delete'>Delete</button></div>"
        );
    });
    $(document).on("click", ".delete", function(){
        $(this).parent().parent().remove();
    });
});
