我已经在互联网和这个网站上搜索了很多小时 - 我发现了许多类似的问题,并尝试了人们提出的建议,但我似乎无法使用我正在使用的代码获得任何东西。
这是发生了什么:
我有两个文本字段(dateOpened 和 dateClosed),我希望日期出现在其中。当您单击每个文本字段时,会出现日期选择器(我能够让该部分工作)。但是,我在获取日期显示在 dateClosed 文本字段中时遇到问题。
对于 dateOpened - 当我单击文本字段时,会出现日期选择器,我选择一个日期,它会出现在该文本字段中。效果很好!
问题:
对于 dateClosed - 当我单击文本字段时,日期选择器出现(效果很好),我选择了一个日期,但它出现在 dateOpened 文本字段中,而不是应有的 dateClosed。
对于如何让日期出现在 dateClosed 文本字段中的任何建议,我将不胜感激。谢谢!!!:)
