我想知道如何執行兩個功能handleClose，并saveData在onclick方法在同一時間。
我想執行的地方：
<Button variant="contained" onClick={saveData}>
Save
</Button>
完整代碼：

<Button variant="contained" onClick={() => {
saveData();
handleClose();
}}>
Save
</Button>
uj5u.com熱心網友回復：
最直接的方法是將它們包裝在 jsx 屬性中。如果你沒有明白我的意思，請看下面的例子：
例子：
import react from "react";
const App = () =>{
return(
<div id="foo-bar">
<button onClick={()=>{
foo()
foo2();
}}/>
</div>
);
}
uj5u.com熱心網友回復：
您可以在onClick方法上呼叫任何處理程式或函式。
現場示例：
const App = () => {
const saveData = () => {
console.log("save data called");
};
const handleClose = () => {
console.log("handleClose");
};
const handleOnClick = () => {
handleClose();
saveData();
};
return (
<div>
<button onClick={handleOnClick}>Save</button>
</div>
);
};
ReactDOM.render(<App />, document.getElementById("root"));<script crossorigin src="https://unpkg.com/react@17/umd/react.production.min.js"></script>
<script crossorigin src="https://unpkg.com/react-dom@17/umd/react-dom.production.min.js"></script>
<div id="root"></div>轉載請註明出處，本文鏈接：https://www.uj5u.com/yidong/357350.html
