我修复了额外的 jQuery 代码用户问题。但错误仍然相同。这里有谁想要使用这个解决方案。

$('#fileupload').bind('fileuploaddone', function (e, data) {
    loadImages(data);
});

function loadImages(data) {
    $.getJSON('my.php', function (data) {
       var result = tmpl('show-template', data);
          $('#houseImagesDiv').html(result).fadeIn();
       });
}

loadImages();

$(document).on('click','.delete',function(event){
    event.preventDefault();
    $.getJSON($(this).data('url')).done(function () {
        loadImages();
    });
});

我在表格上添加了

<div id="houseImagesDiv"></div>

我做了空的下载js模板。

<script id="template-download" type="text/x-tmpl">
  // need empty row here 
</script>

我为新 div 创建新模板。

<script id="show-template" type="text/x-tmpl">
{% for (var i=0, file; file=o.files[i]; i++) { %}
    <div class="template-download col-md-2 text-center" >
        <div>
            <span class="preview">
                <img src="{%=file.thumbnailUrl%}">
            </span>
        </div>
        <div class="mt10 text-center">
            <button class="btn btn-danger delete"
                    data-type="{%=file.deleteType%}"
                    data-url="{%=file.deleteUrl%}"{% if (file.deleteWithCredentials) { %}
                    data-xhr-fields='{"withCredentials":true}'{% } %}>
                <i class="glyphicon glyphicon-trash"></i>
            </button>
        </div>
    </div>
{% } %}
</script>
