如何使用jquery将删除图像/图标附加到div内的图像

Question

我正在尝试上传一些图像并在空DIV中显示它们并在上传后如果我将鼠标悬停在图像上我应该得到一个删除图标,以便用户应该能够用动画删除它并将下一个图像移动到删除形象位置.

我如何实现这一目标？

这是我上传和附加到div容器的方式:

<script type="text/javascript">
 $(function () {
     document.getElementById('Nextbutton').style.visibility = "hidden"; // show 
     $("#uploader").plupload({
         // General settings
         runtimes: 'gears,flash,silverlight,browserplus,html5',
         url: 'Test.aspx',
         max_file_size: '10mb',
         max_file_count: 20,
         chunk_size: '1mb',
         unique_names: true,

         filters: [
            { title: "Image files", extensions: "jpg,gif,png" },
            { title: "Zip files", extensions: "zip" }
        ],


         flash_swf_url: 'js/plupload.flash.swf',


         silverlight_xap_url: 'js/plupload.silverlight.xap'
     });



     $('form').submit(function (e) {
         var uploader = $('#uploader').plupload('getUploader');

         if (uploader.files.length > 0) {

             uploader.bind('StateChanged', function () {
                 if (uploader.files.length === (uploader.total.uploaded + uploader.total.failed)) {
                     $('form')[0].submit();
                 }
             });

             uploader.start();

         }
         else
         //alert('You must at least upload one file.');

             return false;
     });
     var uploader = $('#uploader').plupload('getUploader');

     uploader.bind('FilesAdded', function (up, files) {
         //              jQuery('#container a').html('');
         $('#container > *').remove();
         var i = 0;
         while (i++ < up.files.length) {
             var ii = i;
             while (ii < up.files.length) {
                 if (up.files[i - 1].name == up.files[ii].name) {
                     $.msgBox({
                         title: "Ooops",
                         content: "There is already an image with the same filename and cannot be added.",
                         type: "error",
                         showButtons: true,
                         opacity: 0.9,
                         autoClose: false
                     });
                     uploader.removeFile(up.files[ii]);
                 } else {
                     ii++;
                 }
             }
         }
         if (i > 20) {
             $.msgBox({
                 title: "Info",
                 content: "Uuh! Please don't put me any more files.<br>Maximum Upload limit is only 20 Images.<br>Rest of the Images will be removed.",
                 type: "info",
                 showButtons: true,
                 opacity: 0.9,
                 autoClose: false
             });
             $('#uploader_browse').hide();
         }
     });
     uploader.bind('FilesRemoved', function (up, files) {
         if (up.files.length < 20) {
             $('#uploader_browse').fadeIn("slow");
         }
     });


     uploader.bind('FileUploaded', function (up, file, res) {
         $('#container').append("<div class='container a'><a href='uploads/" + document.getElementById("currentDirectory").value + "/" + file.name + "'  rel='prettyPhoto' target='blank'><img src='uploads/" + document.getElementById("currentDirectory").value + "/" + file.name + "' width='64' height='64'/></a></div>");



         var $imageContainers = $('#container a');

         $imageContainers.each(function (index) {
             $(this).delay(index * 50).fadeTo(400, 0.5);
         });

         $imageContainers.mouseover(function () {
             $(this).css('opacity', 1);
             $(this).find('span.del').show();
         });
         $imageContainers.mouseout(function () {
             $(this).css('opacity', 0.5);
             $(this).find('span.del').hide();
         });



         if (uploader.files.length === (uploader.total.uploaded + uploader.total.failed)) {
             document.getElementById('Nextbutton').style.visibility = "visible"; // show 
             showStickySuccessToast();
         }
         uploader.removeFile(file);
     });

 });


     function randomString(length) {
         var chars = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz'.split('');

         if (!length) {
             length = Math.floor(Math.random() * chars.length);
         }

         var str = '';
         for (var i = 0; i < length; i++) {
             str += chars[Math.floor(Math.random() * chars.length)];
         }
         return str;
     }

    </script>

HTML

<div id="container">
  <div class="image" id="image1" style="background-image:url(http://lorempixel.com/100/100/abstract);">
    <a href="#" class="delete">Delete</a>
  </div>
  <div class="image" id="image2" style="background-image:url(http://lorempixel.com/100/100/food);">
    <a href="#" class="delete">Delete</a>

    <a href="#" class="delete">Delete</a>
  </div>
</div>

CSS

#container { overflow:auto; }
.image { width:100px;height:100px;float:left;position:relative; }
a.delete { display:none;position:absolute;top:0;right:0;width:30px;height:30px;text-indent:-999px;background:red; }
.image:hover a.delete { display:block; }

jQuery的/ JavaScript的

$(document).ready(function(){

  $('a.delete').on('click',function(e){
    e.preventDefault();
    imageID = $(this).closest('.image')[0].id;
    alert('Now deleting "'+imageID+'"');
    $(this).closest('.image')
      .fadeTo(300,0,function(){
        $(this)
          .animate({width:0},200,function(){
            $(this)
              .remove();
          });
      });
  });

});
