问题描述
有没有办法得到一个ASP.NET文本框只接受货币值,而当控制验证,先插入一个$符号?
Is there a way to get an ASP.NET textbox to accept only currency values, and when the control is validated, insert a $ sign beforehand?
例如:
10.23成为$ 10.23
$ 1.45 $停留
10.A引发错误,由于不是一个有效的数字,以
10.23 becomes $10.23
$1.45 stays $1.45
10.a raises error due to not being a valid number
我有一个验证的数量RegularEx pressionValidator是有效的,但我不知道如何强制$符号到文字。我怀疑的JavaScript可能会奏效,但想知道是否有另一种方式来做到这一点。
I have a RegularExpressionValidator that is verifying the number is valid, but I don't know how to force the $ sign into the text. I suspect JavaScript might work, but was wondering if there was another way to do this.
推荐答案
在ASP.NET 从控制可以完成你的要求了。
The ASP.NET MaskedEdit control from the AJAX Control Toolkit can accomplish what you're asking for.
