Question

我有一个下面的表格,我想克隆,增加id(att1)和它的输入,textareas等,并附加到与会者div.任何帮助非常感谢.一直在破坏我的头脑......

我只有......

$(function () {
        var index = 1;


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

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

看小提琴.

添加一个类attendee到div id="att1"

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

和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
});
