解决方法
MVC为它提供的每个数据注释验证器提供了不显眼的验证器.从
Validation with Data Annotation Validators开始,这是列表:
Using the Data Annotation Validator Attributes
When you use the Data Annotations Model Binder,you use validator attributes to perform validation. The System.ComponentModel.DataAnnotations namespace includes the following validator attributes:
- Range – Enables you to validate whether the value of a property falls
between a specified range of values.- ReqularExpression – Enables you to validate whether the value of a
property matches a specified regular expression pattern.- required – Enables you to mark a property as required.
- StringLength –
Enables you to specify a maximum length for a string property.- Validation – The base class for all validator attributes.
- DataType – Additional validations for specific data types,like phone numbers,credit cards and email addresses. Not in the referenced link.
有关可以包含在您的应用程序中的其他验证器,另请参见https://dataannotationsextensions.apphb.com.
就客户端标记属性而言,这些属性由上述注释生成的不显眼的适配器处理.它们以“data-val-”为前缀.验证器的其他参数将作为附加属性添加.例如:
正则表达式变为data-val-regex =“Message”data-val-regex-pattern =“some pattern”
来自MVC3 jQuery.validate.unobtrusive.js:
adapters.addSingleVal("accept","exts") .addSingleVal("regex","pattern"); adapters.addBool("creditcard") .addBool("date") .addBool("digits") .addBool("email") .addBool("number") .addBool("url"); adapters.addMinMax("length","minlength","maxlength","rangelength") .addMinMax("range","min","max","range"); adapters.add("equalto",["other"],function (options) { // removed for brevity }); adapters.add("required",function (options) { // removed for brevity }); adapters.add("remote",["url","type","additionalfields"],function (options) { // removed for brevity });
