时间: 2023-07-19 22:39:01 浏览: 121
可以通过覆盖原有的message来修改rules的message。比如,如果要修改FirstName的message为"请输入有效的名字",可以在调用rules的页面中,添加如下代码:
```
import { rules } from '路径';
rules.FirstName[0].message = "请输入有效的名字";
```
这样就会将FirstName的第一个规则的message修改为"请输入有效的名字"。其他规则的修改方法类似,只需要找到对应的规则,修改其中的message即可。

const std::string & name() const
`const std::string & name() const` 是 C++ 中的一种函数声明,通常在类的成员函数中看到,表示这个函数是一个常量引用返回类型(`const std::string&`),并且它是一个常量成员函数(`const`)。这个函数的主要作用可能是获取对象的名称属性,且保证不会修改这个名称。
简单来说:
1. `const` 前缀表示该函数不会改变对象的状态,这里的对象是指调用该函数的那个实例。
2. `std::string &` 表示返回一个 string 类型的对象的引用,允许在函数外部修改被引用的内容。
3. `name()` 是函数名,可能是某个类中用于获取名字的方法。
例如,在一个名为 Person 的类中:
```cpp
class Person {
public:
const std::string& getName() const { return m_name; } // 假设 m_name 是私有变量存储姓名
private:
std::string m_name;
};
```
你可以像这样调用它:
```cpp
Person p;
const std::string& name = p.getName(); // 获取并存储对象p的姓名,不允许修改
```

在这段代码中,可以使用 react-i18next 来对 message 进行文字转换。具体操作如下:
1. 首先,在组件中引入 react-i18next 库。
2. 在组件中使用 useTranslation hook 来获取 t 函数,用于进行文字转换。
3. 在 rules 对象中的每个 message 属性中,使用 t 函数对需要转换的文字进行包裹。例如:
```
message: t("First Name is required")
```
完整代码如下:
```
import { useTranslation } from "react-i18next";
const { t } = useTranslation();
export const rules: Rules = {
FirstName: [
{
type: "string",
required: true,
message: t("First Name is required"),
validator(rule, value, callback, source, options) {
const firstNameValue = Object.keys(source).find(
(k) => k.indexOf("FirstName") >= 0
);
if (firstNameValue) {
source["FirstName"] = source[firstNameValue];
}
callback();
},
},
{ pattern: /^[a-z\s]{1,25}$/i, message: t("Invalid First Name") },
],
LastName: [
{
type: "string",
required: true,
message: t("Last Name is required"),
validator(rule, value, callback, source, options) {
const firstNameValue = Object.keys(source).find(
(k) => k.indexOf("LastName") >= 0
);
if (firstNameValue) {
source["LastName"] = source[firstNameValue];
}
callback();
},
},
{ pattern: /^[a-z\s]{1,25}$/i, message: t("Invalid Last Name") },
],
MiddleName: [{ pattern: /^[a-z\s]{1,25}$/i, message: t("Invalid Middle Name") }],
BirthDate: [
{
type: "string",
validator(rule, value, callback, source, options) {
if (!value) {
return callback(t("Birth Date is required"));
}
const date = parse(value, "mm/dd/yyyy", new Date());
const age = differenceInYears(new Date(), date);
if (age < 22) return callback(t("Patients must be over 22 years old"));
callback();
},
},
],
Gender: {
type: "enum",
required: true,
message: t("Gender is required"),
enum: ["male", "female", ""],
},
MRN: [
{ required: true, pattern: /^[a-z0-9\-]{1,50}$/i, message: t("MRN is required") },
],
};
