数据检验插件： Validate插件 添加自定义表单验证

        jQuery.validator.addMethod("ValiPass", function(value, element,params) {

        var exp = new RegExp(params);//实例化正则对象，参数为传入的正则表达式

        return exp.test(value);      //测试是否匹配

        }, "密码必须包含数字、字母大、小写、符号四种");

然后表单验证中

rules: {

                    newPassword: {

                    minlength: 8,

                    maxlength: 12,

                    ValiPass: "^(?![A-Za-z0-9]+$)(?![a-z0-9\\W]+$)(?![A-Za-z\\W]+$)(?![A-Z0-9\\W]+$)[a-zA-Z0-9\\W]{8,}$"

                    }

                },

messages: {

                    newPassword:{

                       minlength: "密码长度不能小于8个字母",

                       ValiPass:"密码必须包含数字、字母大、小写、符号四种"

                    },

                },
