Flex设置自动获得焦点

protected function initializeHandler(event:FlexEvent):void
			{

				ExternalInterface.call("document.getElementById('logClient').focus()");
				focusManager.setFocus(loginName);
				
				
				
			}

<s:TextInput id="loginName" maxChars="250" width="150"/>

'logClient

为该FLEX页面在HTML中的ID,或者就是你这个FLEX页面的名称

如何获得这个名称：

在页面的查看源文件中，有这样一段话：
