我希望能够在用户选择"GO"按钮时在客户端触发表单验证.目前,当选择"GO"按钮时,它不会验证完整的表格.例如,如果我加载表单并选择"Go"按钮而不将焦点放在文本框中,则不会验证任何内容,并且val.Valid()返回true.如果我在文本框中输入了无效数据,则会对该单个项目进行验证; 当我选择"GO"按钮时,val.Valid()返回false.

所以我想要做的是,当用户选择一个按钮或其他事件时,我想触发所有表单验证.

我在MVC 3中这样做

public class TestValidationModel
{
    [Required(ErrorMessage="UserName Is Required")]
    [RegularExpression(@"(\S)+", ErrorMessage = "White space is not allowed")] 
    [StringLength(12, MinimumLength = 3)] 
    public string UserName { get; set; }

    [Required(ErrorMessage="Password Is Required")]
    [StringLength(20, MinimumLength = 3)] 
    public string Password { get; set; }

    [Required(ErrorMessage="Email Address Is Required")]
    [Display(Name = "Email Address")]
    public string EmailAddress{ get; set; }

}
