MMForm

Flex中模拟表单提交，实现一次请求中的多文件上传功能

示例

var form:MMForm = new MMForm();

1. 添加 普通表单域

    var formField : MMFormField = new MMFormField({
    	name:'uname',
    	value:'manjun.han'
    });
   
    form.addFormField(formField);
   

2. 添加 文件/二进制类型表单域，通常使用FileReference获取用户选择的文件进行上传，一次提交中可以添加多个 文件/二进制类型表单域

    var fileRef:FileReference ＝ new FileReference() ;
    fileRef.browser();
    fileRef.load();
    
    // fileRef complete handler中添加文件数据	
    var formField : MMMultipartFormField = new MMMultipartFormField({
    		fieldName:"uploadFieldname" ,	
    		fileName:"uploadFileName",		
    		fileData:fileRef.data,	
    		fileContentType:'image/png'
    });
   

3. 添加事件监听

    var oberserver:MyObserver = new MyObserver() ;
    
    form.setObserverAndHandlers(this , {
    	completeHandler:oberserver.completeHandler,
    	openHandler:oberserver.openHandler,
    	progressHandler:oberserver.progressHandler,
    	securityErrorHandler:oberserver.securityErrorHandler,
    	httpStatusHandler:oberserver.httpStatusHandler,
    	ioErrorHandler:oberserver.ioErrorHandler
    });
    
    // MyObserver handlers
    
    private function openHandler(event:Event):void 
    {
    	trace("openHandler: " + event);
    }
    
    private function completeHandler(event:Event , httpResponseData:Object):void 
    {		
    	trace("completeHandler: " + event);
    }
    
    private function progressHandler(event:ProgressEvent):void 
    {
    	trace("progressHandler: " + event);
    }
    		
    private function securityErrorHandler(event:SecurityErrorEvent):void 
    {
    	trace("securityErrorHandler: " + event);
    }
    
    private function httpStatusHandler(event:HTTPStatusEvent):void 
    {			
    	trace("httpStatusHandler: " + event);
    }
    
    private function ioErrorHandler(event:IOErrorEvent):void 
    {
    	trace("ioErrorHandler: " + event);
    }
   

4. 提交

    var action : String = "http://form.post.action" ;		
    form.submit(action);
