我想知道如何使一个DateField控件带有水印。我想提示/水印文本从MXML设置像这样的：

 ＆LT; MX：的DateField ID =id_datepropmt =选择日期/＆GT;
 

解决方案

使用这种

 ＆LT; MX：的DateField ID =DF文本=选择日期的focusIn =df.text =''/＆GT;
 

或 请参阅该博客的自定义DateField组件 WaterMarkDateField

I would like to know how to make a DateField control with a watermark. I want to set the prompt/watermark text from MXML like this one:

<mx:DateField id="id_date" propmt="Select date" />

Use this

<mx:DateField id="df" text="Select Date"  focusIn="df.text=''" />
