我在一个项目上使用 blueimp 文件上传插件,但在使用 IE8 时遇到了一些困难,主要是什么都没发生!

我的设置尽可能接近插件演示设置 - 文件包含在相同的顺序中,html 结构变化很小,css 是相同的等等。

在其他浏览器 + ie9 中,一切都按预期工作,但在 ie8 中,添加图像的按钮好像没有附加任何内容。

如果我在 ie9 中上传,然后使用开发工具将文档类型切换为 ie8,则可以成功从服务器检索图像。

我很难显示完整的代码,因为不幸的是文档非常复杂,但是页面位于此处: http ://www.yoursplash.co.uk/index.php?route=product/product&product_id=108

这几乎是与文件上传相关的所有内容:

这些是我为了让插件工作而包含的文件

<script src="http://blueimp.github.com/JavaScript-Templates/tmpl.min.js"></script>
<script src="http://blueimp.github.com/JavaScript-Load-Image/load-image.min.js"></script>
<script src="http://blueimp.github.com/JavaScript-Canvas-to-Blob/canvas-to-blob.min.js"></script>
<script src="catalog/view/javascript/jquery/blueimp/jquery.iframe-transport.js"></script>
<script src="catalog/view/javascript/jquery/blueimp/jquery.fileupload.js"></script>
<script src="catalog/view/javascript/jquery/blueimp/jquery.fileupload-fp.js"></script>
<script src="catalog/view/javascript/jquery/blueimp/jquery.fileupload-ui.js"></script>
<script src="catalog/view/javascript/jquery/blueimp/jquery.fileupload-jui.js"></script>

这是我自己的插件实现

'use strict';
$(document).on('ready', function () { 
    $.ajax({
        url: '/index.php?route=product/userimage&usetype=get',
        dataType: 'json',
        context: $('#fileupload')[0]
    }).done(function (result) {
        $(this).fileupload('option', 'done').call(this, null, {result: result});
        if ($('#filesContainer > .template-download').length > 0)
        {
          $('a[href="#user-upload"]').removeClass('selected').siblings('a[href="#user-photos"]').addClass('selected');
          $('#user-upload').hide().siblings('#user-photos').fadeIn(); 
        };
    });
});

$('#fileupload').fileupload(
{
  url: '/index.php?route=product/userimage&usetype=put',
  type: 'POST',
  maxFileSize: 5000000,
  fileInput  : '#imgUp',
  acceptFileTypes: /(\.|\/)(gif|jpe?g|png)$/i,
  process: [
      {
          action: 'load',
          fileTypes: /^image\/(gif|jpeg|png)$/,
          maxFileSize: 5000000 // 20MB
      }
  ],
  filesContainer: '#filesContainer'
})
.bind('fileuploadadded', function (e, data)
{
  $('a[href="#user-upload"]').removeClass('selected').siblings('a[href="#user-photos"]').addClass('selected');
  $('#user-upload').hide().siblings('#user-photos').fadeIn();
})
.bind('fileuploadcompleted', function (e, data) 
{ 
  return $('#filesContainer .uploadedImage').draggable({ containment : 'document', revert : true, appendTo : 'body', helper: function(e,ui){ return $('<img/>',{ src : $(e.target).data('src')}).css('width','150px'); } }).tooltip({ tooltipClass : 'image-gallery-tooltip' , position : { at: 'bottom center'} });
});

这是我实现插件的 HTML

 <form id="fileupload" action="//jquery-file-upload.appspot.com/" method="POST" enctype="multipart/form-data">
          <!-- Redirect browsers with JavaScript disabled to the origin page -->
          <noscript><input type="hidden" name="redirect" value="http://blueimp.github.com/jQuery-File-Upload/"></noscript>
          <!-- The fileupload-buttonbar contains buttons to add/delete files and start/cancel the upload -->
          <div class="row fileupload-buttonbar">
              <div class="span7" style="height:30px;">
                  <p style="float:left;display:block;width:480px;margin-right:10px;padding:5px;">Select images from your computer and once uploaded you may use them in your design</p>
                  <!-- The fileinput-button span is used to style the file input field as button -->
                  <span class="btn btn-success fileinput-button">
                      <i class="icon-plus icon-white"></i>
                      <span>Add images..</span>
                      <input type="file" name="files[]" id="imgUp" multipart>
                  </span>
              </div>
              <!-- The global progress information -->
              <div class="span5 fileupload-progress fade">
                  <!-- The global progress bar -->
                  <div class="progress progress-success progress-striped active" role="progressbar" aria-valuemin="0" aria-valuemax="100">
                      <div class="bar" style="width:0%;"></div>
                  </div>
                  <!-- The extended global progress information -->
                  <div class="progress-extended">&nbsp;</div>
              </div>
          </div>
          <!-- The loading indicator is shown during file processing -->
          <div class="fileupload-loading"></div>
      </form>

任何帮助都会得到很大的帮助——我差点用这个把头发扯掉,因为似乎没有什么好的理由让它不起作用!

对于遇到与我在处理此问题时遇到的相同问题的任何人,该问题与 BlueImp 文件上传器无关,而是 IE < 9 的安全功能,它不允许对文件上传按钮进行编程“点击”。

The actual cause of the problem was that I had hidden the form input so that I could present my own styled 'button' and triggered the click on the input using jQuery - my solution was to instead set the form inputs' opacity to 0 using CSS, and then position it over my 'pretty' button using absolute positioning.
