用于日期验证的焦点文本框. [英] On focus textbox for date validation.

问题描述

大家好，

在这里，我将验证此格式yyyy/MM/dd usinf rangevalidator的正常工作，但我的任务是，如果用户输入错误的日期，则光标不能移到下一个字段，直到用户输入正确的日期，光标必须是相同的字段.你能告诉我我该怎么做吗.

告诉我任何一种程序，无论是其asp.net验证程序还是JavaScript，但我都需要使用它.

推荐答案

在客户端(Javascript)中保留一个临时变量.在其中设置焦点对准的最后一个controlID.

现在，每当验证失败发生时，请使用此temp变量.如果验证失败，请将bool标志设置为true.

现在，在每个控件上定义onfocus.在其中，检查bool标志是否为true，如果是，则使用temp变量，并获取具有焦点的最后一个控件.放回去完成.

尝试！

Keep a temporary variable in client side (Javascript). Set the last controlID in it that was in focus.

Now, use this temp variable whenever the validation failure occurs. In case of validation failure, set a bool flag to true.

Now, define onfocus on each control. In it, check if bool flag is true, if so, use the temp variable and get the last control that had focus. set it back. Done.

Try!

使用正则表达式验证器
并使用它
ValidationExpression =(0 [1-9] | [12] [0-9] | 3 [01])[-/.](0[1-9]|1[012])[-/.](19 | 20)\ d \ d

use Regular Expression Validator
and use it
ValidationExpression="(0[1-9]|[12][0-9]|3[01])[- /.](0[1-9]|1[012])[- /.](19|20)\d\d

你好，

尝试将SetFocusOnError属性设置为true.如果那不起作用，请查看这篇文章.
