            <label>

        </div>
        <div id="section2" class="phoneDetails">

            <input type="text" name="Phone1" value="" />
            <input type="text" name="value" value="" />
        </div>
        <div id="section3" class="phoneDetails">
            <label>
                <input type="checkbox" id="check3" value="1" /></label>
            <input type="text" name="Phone1" value="" />
            <input type="text" name="value" value="" />
        </div>
        <div id="section4" class="phoneDetails" style="display:none">
            <label> 
                <input type="checkbox" id="check4" value="1" /></label>
            <input type="text" name="Phone1" value="" />
            <input type="text" name="value" value="" />
        </div>
        <div id="button">
            <input id="btnAdd" type="button" value="+">
            <input id="btnRemove" type="button" value="-">
        </div>
    </div>

    <script>
        debugger;
        $(document).ready(function () {
            var sections = [];
            $('[id^="section"]').each(function () {
                sections = this;
            });
        });
        $("#btnAdd").click(function () {
            alert($('[id^="section"]:visible').length);
            $('#section2').insertAfter($('[id^="section"]:visible:last'));
        });
         $("#btnRemove").click(function () {
             $('input:checkbox[id^="check"]:checked').each(function () {
                 $(this).closest('div').remove();
             });
        });

    </script>
</asp:Content>

推荐答案

（document）.ready（function（）{

(document).ready(function () { var sections = [];

（'[id ^ =section]'）。each（function（）{
sections = this;

}）;

('[id^="section"]').each(function () { sections = this; }); });

（＃btnAdd）。click（function（）{
alert（

("#btnAdd").click(function () { alert(
