jquery.fileupload插件 ie9下不支持上传

根据https://github.com/blueimp/jQuery-File-Upload/wiki/Browser-support

The following browsers support at least one form of AJAX style file uploads, either via XHR or via the Iframe Transport:

Desktop browsers

  • Google Chrome
  • Apple Safari 4.0+
  • Mozilla Firefox 3.0+
  • Opera 11.0+
  • Microsoft Internet Explorer 6.0+

1、要支持上传.必须支持AJAX style file uploads, either via XHR or via the Iframe Transport,

这三种中的一种，所以我选择了最后一种Iframe Transport

，根据Iframe Transport链接下的地址https://cmlenz.github.io/jquery-iframe-transport/

1、下载jquery.iframe-transport.js。然后引入该js文件

2、根据 https://cmlenz.github.io/jquery-iframe-transport/

加入参数对于ie10以下的浏览器加入参数:iframe=true

var url = ctx   + fileServiceURL.saveFiles;//上传文件的地址

                    var error = $(‘<span/>‘).text(file.error);
                    $(data.context.children()[index])
                        .append(‘<br>‘)
                        .append(error);
                });
            }
             
        });
