Flex DateField 使用 Editable = True 验证日期 [英] Flex DateField validate date with Editable = True

问题描述

我们有一个 Editable = true 的 Datefield 组件

We have a Datefield component with Editable = true

<mx:DateField id="startDate"  
                                  width="120"
                                  editable="true"
                                  formatString="MM/DD/YYYY"
                                  selectableRange="{{rangeStart : new Date(2010,0,1), rangeEnd : new Date()}}"
                                  showToday="true"
                                  labelFunction="formatDate" 
                                  restrict="[0-9] '\/'" change="startDate_clickHandler(event)"
                                  yearNavigationEnabled="true" 
                                  text="{}" tabIndex="15" />

日历拥有我们想要的一切(只能选择 01/01/2010 之后的有效日期).现在的问题是，如果用户输入 (Editable = true) 无效日期或任何日期 <;2010 年 1 月 1 日，我如何验证该日期并显示警告，指出日期无效.请对此提供任何帮助，我们将不胜感激.

The Calendar has everything we want (able to choose a valid date only after 01/01/2010). Now the issue is that if the user enters (Editable = true) an invalid date or any date < 01/01/2010, how can i validate that and show an alert saying that the date is invalid. Please any help on this would be appreciated.

谢谢

推荐答案

DateField 组件有一个您可以收听的 valueCommit 事件.因此，您可以将处理程序附加到该事件并根据需要进行验证.

The DateField component has a valueCommit event that you can listen to. So you can attach a handler to that event and do the validation as required.
