如何不允许FreeTextBox内容充满空格字符？ [英] How do not allow FreeTextBox content with full of space characters?

问题描述

我的aspx页面中有一个FreeTextBox FTB。







< asp：ValidationSummary ID = QUOT;警报" RUNAT = QUOT;服务器"的CssClass = QUOT; failureNotification" HeaderText ="" />



< asp：RequiredFieldValidator ID =" RequiredFieldValidator1" RUNAT = QUOT;服务器"的ControlToValidate = QUOT; FTB"的ErrorMessage = QUOT;内容不能为空">< / asp：RequiredFieldValidator>



我之前使用过RequiredFieldValidator进行`TextBox`控件。



现在我将它用于FreeTextbox控件。如果我让FreeTextBox为空，它可以正常工作，但是当FreeTextBox充满空格字符时我会显示ErrorMessage。



根据建议，我使用RegularExpressionValidator



< asp：RegularExpressionValidator ID =" rev" RUNAT = QUOT;服务器"的ControlToValidate = QUOT; FTB" ErrorMessage ="内容不能只是空格字符 ValidationExpression =" [^ \ _s] +" />



但是RegularExpressionValidator拒绝文本中的任何空格字符（单词之间的空格）。

我只想不允许带有空格字符的文本。



帮助!!!

I have a FreeTextBox FTB in my aspx page.



<asp:ValidationSummary ID="Alert" runat="server" CssClass="failureNotification" HeaderText=""/>

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="FTB" ErrorMessage=" Content cannot be empty"></asp:RequiredFieldValidator>

I've used RequiredFieldValidator before for `TextBox` control.

Now I use it for FreeTextbox control. It works fine if I let the FreeTextBox empty, but I doent show the ErrorMessage when the FreeTextBox is full of space character.

As recommended, I use RegularExpressionValidator

<asp:RegularExpressionValidator ID="rev" runat="server" ControlToValidate="FTB" ErrorMessage="Content cannot be only space character" ValidationExpression="[^\s]+"/>

But the RegularExpressionValidator is deny any space character in the text (space between words).
I just only want to not allow the text which has full of space characters.

Help!!!

嗨克拉克斯，



试试这个

Hi Clarks,

Try this

RegEx：

^ \w +（\ w +）（\ * *）

^\w+( \w+)(\s*)

哪个允许空格，我在这里测试了 http://www.myregextester.com/index.php 工作正常，你也做了测试并确认了。



希望这会对你有所帮助。
