Tom*_*Tom 6 javascript forms reactjs antd

我找不到关于这个主题的太多信息。以下是我想要实现的目标：
我希望用户能够编辑数据库中已存在的采购订单的一些详细信息，然后使用表单重新提交采购订单。原始采购订单的详细信息应显示在表单输入字段中，用户可以直接通过这些字段进行更改，然后提交。
我对网络开发不太了解，所以请耐心等待。
我希望最终的表单对象看起来像这样：
{
po_number:"123abc",
carrier:"Fastway",
items: [{
item_code:"dnh75n",
quantity:"10",
special_requirements:"Add picture of happy dog"
},
{
item_code:"456def",
quantity:"4",
special_requirements:"Do not include lids"
}
]
}
生成的表单输入字段的数量将取决于采购订单中的商品数量。我在下面创建了一个简单的 React 组件来演示我正在尝试做的事情。或者只需查看上面的代码沙箱链接。任何帮助，将不胜感激。我什至找不到有关如何对 ANTd 表单项目进行分组以在采购订单中创建项目数组的信息。我在他们的网站上看到了大量动态表单示例，但我想根据采购订单中预先存在的项目创建表单，而不是添加带有用户输入的字段。
import { Form, Input, Button } from 'antd';
//This is the order that already exists
const order = {
po_number:"123abc",
carrier:"Fastway",
items: [{
item_code:"dnh75n",
quantity:"10",
special_requirements:"Add picture of happy dog"
},
{
item_code:"456def",
quantity:"4",
special_requirements:"Do not include lids"
}
]
};
const GroupForm = () => {
const onFinish = values => {
console.log(values);
}
//Create form fields based off how many items are in the order
const itemInputs = order.items.map(item => {
return (
<div>
<b>Item{" " + item.item_code}</b>
<Form.Item name={item.item_code + "_quantity"} label="quantity">
<Input defaultValue={item.quantity} style={{width: "500px"}} />
</Form.Item>
<Form.Item name={item.item_code + "_requirements"} label="speacial requirements">
<Input defaultValue={item.special_requirements} style={{width: "500px"}} />
</Form.Item>
</div>
);
});
return(
<div>
<Form onFinish={onFinish}>
<b>{"Order " + order.po_number}</b>
<Form.Item name="carrier" label="carrier">
<Input defaultValue={order.carrier} style={{width: "500px"}} />
</Form.Item>
<b>Order Items</b>
{itemInputs}
<Form.Item>
<Button type="primary" htmlType="submit"> Change Details </Button>
</Form.Item>
</Form>
</div>
);
}
export default GroupForm;
如果您使用的是 antd 4.9.0+ 版本，您可以initialValue利用Form.List. 这允许您在数组的表单项上设置初始值。或者，您可以initialValues在 上设置该属性Form。这是使用前一种方法的最小可行示例。
import { Form, Input, Button, Space } from "antd";
import { MinusCircleOutlined, PlusOutlined } from "@ant-design/icons";
import React from "react";
//Basic Idea
/*
I want the user to be able to edit some details of a purchase order that already exists in the database,
then resubmit the order with a form.
The details of the purchase order should be orginally displayed in the form input fields,
and the user can change them directly via those fields.
*/
//This is the order that already exists
const order = {
po_number: "123abc",
carrier: "Fastway",
items: [
{
item_code: "dnh75n",
quantity: "10",
special_requirements: "Add picture of happy dog"
},
{
item_code: "456def",
quantity: "4",
special_requirements: "Do not include lids"
}
]
};
const itemInputs = order.items
const GroupForm = () => {
const onFinish = (values) => {
console.log(values);
};
/**
* Edited: `const itemInputs = order.items` above
*/
//Create form fields based off how many items are in the order
// const itemInputs = order.items.map((item) => {
// return {
// item_code: item.item_code,
// quantity: item.quantity,
// special_requirements: item.special_requirements
// };
// });
