Plupload多按钮上传，并获取上传按钮的自定义属性

1、upload多按钮部分HTML代码

<div class="row" id="upload_btn_place">
  <div class="col-md-4">
      1、 材料1
      <a href="javascript:void(0)" class="pickfiles ml-2" id="pickfiles-11" data-type="11" data-file-type="材料1">立即上传</a>     
  </div>
  <div class="col-md-4">
      2、 材料2
      <a href="javascript:void(0)" class="pickfiles ml-2" id="pickfiles-12" data-type="12" data-file-type="材料2">立即上传</a>     
  </div>
</div>

2、多个plupload分开初始化，适用于对上传格式要求不同，上传大小要求不同

$("#uploader").pluploadQueue({
    runtimes: 'html5,flash',
    url: '/upload',
    //上传的文件名是否唯一
    unique_names: true, 
    //是否可以多选
    multi_selection: false, 
    browse_button: "pickfiles-11",
    //触发文件选择对话框的按钮，为那个元素id
    container: 'upload_btn_place',
    flash_swf_url: '/assets/plugins/plupload/Moxie.swf',
    silverlight_xap_url: '/assets/plugins/plupload/Moxie.xap',
    filters: {
        max_file_size: '50M',
        mime_types: [{
            title: "files",
            extensions: "doc,docx"
        }]
    }
});

$("#uploader").pluploadQueue({
    runtimes: 'html5,flash',
    url: '/upload',
    //上传的文件名是否唯一
    unique_names: true,
    //是否可以多选
    multi_selection: false,
    browse_button: "pickfiles-12",
    //触发文件选择对话框的按钮，为那个元素id
    container: 'upload_btn_place',
    flash_swf_url: '/assets/plugins/plupload/Moxie.swf',
    silverlight_xap_url: '/assets/plugins/plupload/Moxie.xap',
    filters: {
        max_file_size: '50M',
        mime_types: [{
            title: "files",
            extensions: "pdf"
        }]
    }
});

3、以组数的形式（browse_button: "[pickfiles-11,pickfiles-12]"）初始化多个plupload，适应于上传格式相同，文件大小限制相同

$("#uploader").pluploadQueue({
    runtimes: 'html5,flash',
    url: '/upload',
    //上传的文件名是否唯一
    unique_names: true,
    //是否可以多选
    multi_selection: false,
    browse_button: "[pickfiles-11,pickfiles-12]",
    //触发文件选择对话框的按钮，为那个元素id
    container: 'upload_btn_place',
    flash_swf_url: '/assets/plugins/plupload/Moxie.swf',
    silverlight_xap_url: '/assets/plugins/plupload/Moxie.xap',
    filters: {
        max_file_size: '50M',
        mime_types: [{
            title: "files",
            extensions: "doc,docx"
        }]
    }
});

4、获取上传按钮的自定义属性

var type,filetype;
$(".pickfiles").click(function(event) {
    type = $(this).attr("data-type");
    filetype  = $(this).attr("data-file-type");
    event.stopPropagation();
});

5、上传效果
