Question

我为jQuery验证编写了以下简单规则：

        jQuery.validator.addMethod("notEqual", function(value, element, param) 
        {
          return this.optional(element) || value != param;
        }, "This field is required");

这样可以说：

        $("#form").validate({
                rules: 
                {
                    field1: {notEqual: "Please Select", required: true},
                    field2: {notEqual: "Year", required: true}
                },
                messages: 
                {
                    field1: {
                            notEqual: "This field is required", 
                            required: "This field is required"
                            }
                    field2: {
                            notEqual: "This field is required", 
                            required: "This field is required"
                            }
                },

                submitHandler: function(form) {
                form.submit();
            }
        });

但是我希望能够说任何一个字段都不允许等于多个事物，例如。

field1: {notEqual: "Please Select" || "Year" || "Some Value", required: true},

但我尝试过这种语法以及安排“ÖR”操作符的其他一些方法，但没有一种方法可行。有人可以帮忙吗？感谢。

您可以将JavaScript数组作为参数传递给验证方法，如jQuery Validation plugin custom method. Multiple parameters

的答案中所述例如

field1: {notEqual: ["Please Select", "Year", "Some Value"], required: true},

然后让你的自定义方法像这样

 jQuery.validator.addMethod("notEqual", function(value, element, param) 
 {
  var result = value != param[0] && value != param[1] && value != param[2]; 
  return this.optional(element) || result;
 }, "This field is required");

jQuery验证。将javascript逻辑（OR）应用于自定义规则
