function OutsourceFileUploadNew(init) init = init ll{}; init.title = lang('upload attachment'),var self = new Window(init).setWidth('40%').setDestroyOnHide(true), self.type ='0utsourceFileUploadNew'.self.attr("id",self.type+ ggNamespace.getCounter...-Go服务器开发

你的代码似乎是一个用于上传文件的 JavaScript 组件，但在多个地方存在语法错误和不完整的部分。以下是修复和补充后的版本：

function OutsourceFileUploadNew(init) {
    init = init || {};
    init.title = lang('upload attachment');
    
    var self = new Window(init).setWidth('40%').setDestroyOnHide(true);
    self.type = '0utsourceFileUploadNew';
    self.attr("id", self.type + ggNamespace.getCounter());
    
    self.fileName = new SmallTextItem({
        title: lang("file name"),
        name: "uploadfile"
    }).setType("file")
      .setAccept(".jpg,.jpeg,.png,.gif,.bmp")
      .setRequired(true);

    // 添加文件类型验证
    self.fileName.addChangeHandler(function() {
        var extMatch = self.fileName.getValue().match(/\.([^\.]+)$/);
        if (extMatch) {
            var ext = extMatch[1].toLowerCase();
            switch(ext) {
                case 'jpg':
                case 'jpeg':
                case 'png':
                case 'gif':
                case 'bmp':
                    break;
                default:
                    // 提示无效附件类型
                    new Bootbox().alert(lang('warn'), lang('invalid file type! Only supports jpg, jpeg, png, gif, bmp'));
                    self.fileName.setValue('');
                    return; // 结束函数执行
            }
        }
    });

    self.uploadButton = new Button({ title: lang('upload'), type: 'primary' });
    self.cancel = new Button({ title: lang('cancel'), type: 'default' });

    self.content = new VLayout();
    self.footer = new HLayout();
    self.form = new DynamicForm();

    // 设置表单项
    self.uploadFileHandler = ggNamespace.functions.AgencyOutsideImportFileUploadWindow.UploadFileHandler;
    
    self.form.setItems(self.fileName);
    
    // 添加内容到布局
    self.content.addMember(self.form);
    
    // 添加按钮到底部布局
    self.footer.addMember(self.uploadButton).addMember(self.cancel);
    
    // 填充空间设置行间距
    self.footer.fillSpaceBefore();
    self.footer.setRowSpacing('5px');

  	// 设置窗口内容与脚部
  	self.setContent(self.content);
  	self.setFooter(self.footer);

  	// 上传按钮点击事件处理
  	self.uploadButton.addClickHandler(function() {
      	self.uploadFileHandler(init);
  	});

  	// 取消按钮点击事件处理
  	self.cancel.addClickHandler(function() {
      	self.hide();
  	});
	
	return self; 
}

// 文件上传处理函数实现
ggNamespace.functions.AgencyOutsideImportFileUploadWindow.UploadFileHandler = function() {
	var self = this;
	let arr = [];

	if (self.form.validate()) {
	    var formData = new FormData($('#' + this.form.attr("id")).find('form')[0]);
	    formData.append("id", init.id);
	    var url="../d/exemptionReduction/saveAttachment";
		
	    // 禁用上传和取消按钮以防止重复提交
	    self.uploadButton.disable();
	    self.cancel.disable();

	    $.ajax({
	        url: url,
	        method: 'post',
	        data: formData,
	        enctype: 'multipart/form-data',
	        processData: false,
	        contentType: false,
	        dataType: 'json',
	        success: function(result) {
	            console.log('result', result);
	            if (result.success) {
	                new Bootbox().setWidth('15vw').alert(lang('alert'), lang('succeed'));
	                arr.push({

	                });
	                // 触发成功事件并隐藏窗口
