Dorado7+BDF2:文件导入

页面完成后，新加了一个文件导入的需求
步骤如下：
1. 新建导入按钮
在分页ToolBar下新增一个ToolBarButton
属性栏Caption设置成${res[“common/Edit”]}，Icon设置为url(>skin>common/icons.gif) -200px -0px。
2. 在Children下新增一个BDF2的RichUpload控件，如图所示
属性栏设置：
id：自由设置
allowFileTypes(允许上传格式)：你想导入文件的格式
processor:响应导入的类名
visible(隐藏):false

事件栏设置：
onReady设置为:

//获取dom
var dom = view.id("RichUpload的id").getDom();
//获取button
var button = dom.firstChild;
//给button设置样式
button.setAttribute("style", "width: 70px;height: 22px;border: #FFF 1px solid;color: #000;background: url(dorado/client/skins/default/base/toolbar-button-bg.gif) no-repeat;cursor: pointer;");

OnSelect设置为

//后台处理数据时候页面的显示状态
self.taskMsg = dorado.util.TaskIndicator.showTaskIndicator("装载中..");

OnSuccess设置为

dorado.util.TaskIndicator.hideTaskIndicator(view.get("#RichUpload的id").taskMsg);
dorado.MessageBox.alert("${res["common/drcg"]}!")
view.get("#sensitiveKeyWordDs").flushAsync();

OnFail设置为

dorado.util.TaskIndicator.hideTaskIndicator(view.get("#RichUpload的id").taskMsg);
dorado.MessageBox.alert(arg.errorMessage);

3. 步骤1的button的设置onclick事件

事件栏编辑onclick事件

                   //获取上传文件控件的dom元素
	               	var dom = view.id("RichUpload的id").getDom();
	               	//找到dom下的input框
	               	var firs = dom.childNodes[2].firstChild;
	               	firs.click();

4.给步骤2中process的类配置
①:在类加载的xml文件中增加文件导入类的bean,如图所示

<bean id="RichUpload的process的value值" class="类的位置+类名"/>

5. 编写后台处理导入的文件
新增class文件

看算法去了！！！
