Usage

Bind to Component

import { makeVModel, useVModel } from "react-vmodel";
export default function Demo() {
  const [data, setData] = useState({
    name: "example",
    tasks: [{ id: 1, name: "test" }],
  });
  const vModel = makeVModel(data, setData);

  //or define with hook
  // const [vModel,data,setData]=useVModel({
  //   { name:'example',
  //      tasks:[{id:1,name:'test'}]
  //     }
  // )
  return (
    <>
      {/* All Bind with react-vmodel */}
      <CustomComponent {...vModel()} />
      {/* //--not with */}
      <CustomComponent
        value={data}
        onChange={(e) => {
          setData(e.target ? e.target.value : e);
        }}
      />

      {/* //Path Bind with react-vmodel */}
      <CustomComponent2 {...vModel("tasks[0].name")} />
      {/* //--not with */}
      <CustomComponent2
        value={data.tasks[0].name}
        onChange={(e) => {
          const clone = structuredClone(data);
          clone.tasks[0].name = e.target ? e.target.value : e;
          setData(clone);
        }}
      />
    </>
  );
}

Bind to input

Text

import { makeVModel } from "react-vmodel";
export default function Demo() {
  const [text, setText] = useState("Hello World");
  const vModel = makeVModel(text, setText);
  return (
    <>
      <input {...vModel()}></input>
      {/* //trim */}
      <input {...vModel.trim()}></input>

      {/* //number */}
      <input type="number" {...vModel()}></input>
      {/* //or */}
      <input {...vModel.number()}></input>
    </>
  );
}

Checkbox

True-False

import { makeVModel } from "react-vmodel";
export default function Demo() {
  const [checked, setChecked] = useState(false);
  const vModel = makeVModel(checked, setChecked);
  return (
    <>
      {/* //true-false */}
      <input type="checkbox" {...vModel.checked()}></input>

      {/* //true 1   false 0 */}
      <input
        type="checkbox"
        {...vModel.checked({ trueValue: 1, falseValue: 0 })}
      ></input>
    </>
  );
}

CheckedList

import { makeVModel } from "react-vmodel";
export default function Demo() {
  const [checkedList, setCheckedList] = useState([]);
  const vModel = makeVModel(checkedList, setCheckedList);
  return (
    <>
      {["one", "two", "three"].map((op) => (
        <input
          key={op}
          type="checkbox"
          {...vModel.checklist({ value: op })}
        ></input>
      ))}
    </>
  );
}

Radio

import { makeVModel } from "react-vmodel";
export default function Demo() {
  const [selected, setSelected] = useState("");
  const vModel = makeVModel(selected, setSelected);
  return (
    <>
      {["one", "two", "three"].map((op) => (
        <input key={op} type="radio" {...vModel.checked({ value: op })}></input>
      ))}
    </>
  );
}

Select

import { makeVModel } from "react-vmodel";
export default function Demo() {
  const [selected, setSelected] = useState("");
  const vModel = makeVModel(selected, setSelected);
  return (
    <>
      {
        <select {...vModel()}>
          {["one", "two", "three"].map((op) => {
            return (
              <option key={op} value={op}>
                {op}
              </option>
            );
          })}
        </select>
      }
    </>
  );
}

Advance Usage

import { makeVModel } from "react-vmodel";
export default function Demo() {
  const [checked, setChecked] = useState(false);
  const vModel = makeVModel(checked, setChecked);
  return (
    <>
      {/* //true 1   false 0 */}
      <input
        type="checkbox"
        {...vModel.checked({ trueValue: 1, falseValue: 0 })}
      ></input>

      {/* custom the same function */}
      <input
        type="checkbox"
        {...vModel((value, onChange) => ({
          checked: value === 1,
          value: String(value === 1),
          onChange: (e) => onChange(e.target.checked ? 1 : 0),
        }))}
      />
    </>
  );
}

Component Model

import { Button, Form, Switch } from "antd";
import { Model } from "react-vmodel";

type FieldType = { status: number };
const initialValues = { status: 1 };

export default function Demo() {
  return (
    <Form onFinish={handleSubmit} initialValues={initialValues}>
      <Form.Item name={"status"}>
        <Model>
          {(vModel) => (
            <Switch
              {...vModel.checked({ trueValue: 1, falseValue: 0 })}
            ></Switch>
          )}
        </Model>
      </Form.Item>
    </Form>
  );
