我在表单中使用multiselect-dropdown-react,我的问题是,如何重置多选字段,我的意思是带有选项的输入?因为我确实看过文档,而且找不到重新设置的方法,所以除了多选之外,整个表单都已重新设置。
const multiselectRef = useRef();
function resetValues() {
multiselectRef.resetSelectedValues();
}
<Multiselect
options={props.categories}
displayValue="name"
onSelect={handlerOnChangeCategory}
onRemove={handlerOnChangeCategory}
ref={resetValues}
/>
谢谢,谢谢!

如果我理解正确,则您希望通过某些操作重置多选。您可以这样简单地完成此操作:
import React, { useState, useRef } from "react";
import { Multiselect } from "multiselect-react-dropdown";
import "./styles.css";
export default function App() {
const [options] = useState([
{ name: "Srigar", id: 1 },
{ name: "Sam", id: 2 }
]);
const multiselectRef = useRef();
const resetSelectField = () => {
multiselectRef.current.resetSelectedValues();
};
return (
<div className="App">
<h1>Hello CodeSandbox</h1>
<h2>Start editing to see some magic happen!</h2>
<Multiselect
options={options} // Options to display in the dropdown
displayValue="name" // Property name to display in the dropdown options
ref={multiselectRef}
/>
<button onClick={resetSelectField}>Reset</button>
</div>
);
}
