React onMouseDownCapture is an event handler that gets triggered whenever we press the mouse button. like onMouseDown, but the difference is that onMouseDownCapture acts in the capture phase whereas onMouseDown acts in the bubbling phase i.e. phases of an event.
Prerequisite:
- Introduction and installation of ReactJS
- Phases of JavaScript Event
Syntax:
<element onMouseDownCapture={function}/>
Creating React Application:
Step 1: Create a react project folder, for that open the terminal, and write the command npm create-react-app folder name. Suppose you have already installed create-react-app globally. If you haven’t, install create-react-app globally using the command npm -g create-react-app or install locally by npm i create-react-app.
npm create-react-app project
Step 2: After creating your project folder(i.e. project), move to it by using the following command.
cd project
Project Structure: It will look like this:
Example: In this example, we are adding a text within the <p> tag i.e. “Click Me!”, when the user will click on this element the onMouseDownCapture event will call onMouseDownCaptureHandler, a function that will show a text “onMouseDownCapture Event!” whenever we press the mouse button over the element.
App.js
Javascript
function App() { const onMouseDownCaptureHandler = () => { console.log("onMouseDownCapture Event!"); }; return ( <div className="App"> <h1> Hey Geek!</h1> <p onMouseDownCapture={onMouseDownCaptureHandler}> Click Me! </p> </div> );}export default App; |
Step to Run the Application: Run the application using the following command from the root directory of the project.
npm start
Output:
