推荐答案

您可以使用Javascript RegEx验证货币输入(基于文本框名称的假设).快速搜索Google词以揭示给您的内容；
validate-currency-amount-using-regular-expressions-in-javascript [ ^ ]

You can use Javascript RegEx to validate for a currency input (assumption based on name of text box). A quick search of a google term to reveal that gives you;
validate-currency-amount-using-regular-expressions-in-javascript[^]

使用Regex
JavaScript货币验证 [货币格式 [最大长度 [

Using Regex
Javascript Currency Validation[^]

without Regex
Money Format[^]

BTW you may use maxlength[^] Attribute to specify the maximum length of the control.
