单击模态中的图像后如何显示图像？

Question

我的HTML代码是这样的:

<!-- Button trigger modal -->
<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">Launch demo modal</button>
<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                 <h4 class="modal-title" id="myModalLabel">Modal title</h4>

            </div>
            <div class="modal-body">


            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
            </div>
        </div>
        <!-- /.modal-content -->
    </div>
    <!-- /.modal-dialog -->
</div>
<!-- /.modal -->

我的Javascript代码是这样的:

<script type="text/javascript">

    htmlData = '';
    htmlData = 'Photos<a href="#" id="hotel_photo" data-hotel-code="nases">(Click to View)</a><br><br>';
    htmlData += '<div class="imageHotel"></div>';

    $('#myModal').find('.modal-body').html(htmlData);

    $(".imageHotel").hide();
    $(document).on("click", "#hotel_photo", function(event){
        $(".imageHotel").toggle();
        event.preventDefault();
        htmlData += '<div id="gallery_hotel">';

            htmlData = '<img id="largeImage" src="http://www.workshop.rs/demo/gallery-in-4-lines/images/image_01_large.jpg" />';

        htmlData += '</div>';


        htmlData += '<div id="thumbs_hotel">';

            htmlData += '<img src="http://www.workshop.rs/demo/gallery-in-4-lines/images/image_01_thumb.jpg" />';
            htmlData += '<img src="http://www.workshop.rs/demo/gallery-in-4-lines/images/image_02_thumb.jpg" />';
            htmlData += '<img src="http://www.workshop.rs/demo/gallery-in-4-lines/images/image_03_thumb.jpg" />';
            htmlData += '<img src="http://www.workshop.rs/demo/gallery-in-4-lines/images/image_04_thumb.jpg" />';
            htmlData += '<img src="http://www.workshop.rs/demo/gallery-in-4-lines/images/image_05_thumb.jpg" />';

        htmlData += '</div>';

        $('.imageHotel').html(htmlData);

    });


    $('#thumbs_hotel').delegate('img','click', function(){
                                               // alert('tes');
        $('#largeImage').attr('src',$(this).attr('src').replace('thumb','large'));

    });

</script>

演示是这样的:https://jsfiddle.net/oscar11/10td0yww/1/

单击图像列表中的图像时,图像未更改.虽然我已经打电话给id thumb hotel了.

当我不使用模态.它正在发挥作用

当我使用模态.它不起作用

解决我的问题的任何解决方案？

非常感谢你

您正走在对动态生成的元素使用委托事件方法的正确道路上。但是，您应该绑定 using.on()而不是.delegate()

从 jQuery 1.7 开始，.delegate()已被该.on()方法取代，

当绑定事件用作imageHotel父静态容器时，您将完全替换thumbs_hotel元素。

$('.imageHotel').on('click', '#thumbs_hotel img', function() {
    $('#largeImage').prop('src', this.src.replace('thumb', 'large'));
});
