jquery - 克隆形式和增量

Question

我有一个下面的表单，我想克隆它，增加 id(att1) 及其输入、文本区域等，然后附加到与会者 div。非常感谢任何帮助。搞得我头都晕了……

我所拥有的只是...

$(function () {
        var index = 1;


    $(".add").click(function () {
            index++;

        $("#att1").clone(true).removeAttr("id").attr("id", "att" + index).appendTo("#attendees");
            alert(index);
    });
});

HTML:

    <div id="attendees">
            <div id="att1">
                    <fieldset>
                        <legend><span class="legend">Attendee 1 Booking Details</span></legend>
                        <p name="test">
                        <label for="A_Title_1">Title: <span class="req">*</span></label>
                        <input name="A_Title_1" id="A_Title_1" value="" type="text" class="f_input" />
                        </p>

                        <p>
                        <label for="A_Forename_1">Forename: <span class="req">*</span></label>
                        <input name="A_Forename_1" id="A_Forename_1" type="text" class="f_input" />
                        </p>

                        <p>
                        <label for="A_Surname_1">Surname: <span class="req">*</span></label>
                        <input name="A_Surname_1" id="A_Surname_1" type="text" class="f_input" />
                        </p>

                        <p>
                        <label for="A_Info_1">Additional Info: </label>
                        <textarea name="A_Info_1" id="A_Info_1" cols="20" rows="10"></textarea>
                        <span class="info">Please include any infomation relating to dietary/ access/special requirements you might have.</span>
                        </p>
                    </fieldset>
                    </div>
<a href="#" class="add">Add more</a>

    </div>

请参阅fiddle .

将类(class)attendee添加到div id="att1"

 <div id="att1" class="attendee">

还有 JS:

$(function(){
    var template = $('#attendees .attendee:first').clone(),
        attendeesCount = 1;

    var addAttendee = function(){
        attendeesCount++;
        var attendee = template.clone().find(':input').each(function(){
            var newId = this.id.substring(0, this.id.length-1) + attendeesCount;
            $(this).prev().attr('for', newId); // update label for (assume prev sib is label)
            this.name = this.id = newId; // update id and name (assume the same)
        }).end() // back to .attendee
        .attr('id', 'att' + attendeesCount) // update attendee id
        .prependTo('#attendees'); // add to container
    };

    $('.add').click(addAttendee); // attach event
});
