我一直在研究这段代码,现在试图让它正常工作.我想限制使用上传更多2张图片.

var upa = $('.uploader').plupload('getUploader');给出Uncaught TypeError:Object [object Object]错误的行没有方法'plupload'

    var maxfiles=2;
    $('.uploader').each(function(){
        var $uploader = $(this);

                FilesAdded: function(up, files) {
                    plupload.each(files, function(file) {
                        if (up.files.length > maxfiles) {
                            up.removeFile(file);
                        }
                        var upa = $('.uploader').plupload('getUploader');
