使用 KendoUI 的 .kendoMaskedTextBox，您将如何屏蔽特定字符？

Question

我可以使用 KendoUI 的 .kendoMaskedTextBox 轻松屏蔽文本字段输入：

$("#MainContent_txtMailingZip").kendoMaskedTextBox({
    mask: "L0L 0L0"
});

但是，我现在只想接受字母 M 和 L 作为第一个字符。

如何做到这一点？

Answer 1

我认为这不可能，以下是 API 文档中的有效掩码规则。 http://docs.telerik.com/kendo-ui/api/javascript/ui/maskedtextbox#configuration-mask

0 - Digit. Accepts any digit between 0 and 9.

9 - Digit or space. Accepts any digit between 0 and 9, plus space.

# - Digit or space. Like 9 rule, but allows also (+) and (-) signs.

L - Letter. Restricts input to letters a-z and A-Z. This rule is equivalent to [a-zA-Z] in regular expressions.

? - Letter or space. Restricts input to letters a-z and A-Z. This rule is equivalent to [a-zA-Z] in regular expressions.

& - Character. Accepts any character. The rule is equivalent to \S in regular expressions.

C - Character or space. Accepts any character. The rule is equivalent to . in regular expressions.

A - Alphanumeric. Accepts letters and digits only.

a - Alphanumeric or space. Accepts letters, digits and space only.

. - Decimal placeholder. The decimal separator will be get from the current culture used by Kendo.

, - Thousands placeholder. The display character will be get from the current culture used by Kendo.

$ - Currency symbol. The display character will be get from the current culture used by Kendo.

Answer 2

我在字段中添加了正则表达式验证。虽然它不满足按键过滤器，但它可以解决问题：

    <asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" CssClass="field-validation-error" ErrorMessage="<%#ResourceApplicantIntakeCustomerInformation.msgInvalidPostalCode%>" ControlToValidate="txtMailingZip" ForeColor="red" Enabled="true" 
        ValidationExpression="^[KLMNP][0-9][A-Z] ?[0-9][A-Z][0-9]$"></asp:RegularExpressionValidator>

就是你想要的：

$("#MainContent_txtMailingZip").kendoMaskedTextBox({
    mask: "^0L 0L0",
    rules: { "^": /[ML]/ }
});
