React onTouchStart Event

React onTouchStart event fires when the user touches one or more points in the element or tag. Similar to other elements in it, we have to pass a function for process execution.

It is similar to the HTML DOM ontouchstart event but uses the camelCase convention in React.

Syntax:

onTouchStart={function}

Parameter :

• function that will call once user touch any part of element or tag.

Return type:

• event: It is an event object containing information about the event like target element and values

Example 1 : In this example we implemented TouchStart area in it where when user touch it will gives an message in browser console through function.

Javascript

// App.js
import "./App.css"
const App = () => {
    const function1 = (event) => {
        console.log("Touch Start!")
    }
    return (
        <div className="App">
            <h1>GeeksforGeeks</h1>
            <h2>Touch inside Shaded Region</h2>
            <div className="Shaded" onTouchStart={function1}>
            </div>
        </div>
    );
}
export default App;

CSS

/*App.css*/
.App {
    min-width: 30vw;
    margin: auto;
    text-align: center;
    color: green;
    font-size: 23px;
}

.Shaded {
    background-color: lightgray;
    height: 200px;
    width: 300px;
    margin: auto;
    border-radius: 6px;
}

Example 2 : In this example, we implemented an area where the user, when touched, will get an alert that a touch event is fired.

Javascript

// App.js
import "./App.css"
const App = () => {
    const function1 = (event) => {
        alert("Touch Start")
    }
    return (
        <div className="App">
            <h1>GeeksforGeeks</h1>
            <h2>Touch inside Shaded Region</h2>
            <div className="Shaded" onTouchStart={function1}>
            </div>
        </div>
    );
}
export default App;

CSS

/*App.css*/
.App {
    min-width: 30vw;
    margin: auto;
    text-align: center;
    color: green;
    font-size: 23px;
}

.Shaded {
    background-color: lightgray;
    height: 200px;
    width: 300px;
    margin: auto;
    border-radius: 6px;
