I am new to React.js and just now i was learning the concept of ref
in React. They have new createRef API in V16.3. I was trying to learn this from REACT DOC's like this -
import React from "react";
export class MyComponent extends React.Component {
constructor(props) {
super(props);
// create a ref to store the textInput DOM element
this.textInput = React.createRef();
this.focusTextInput = this.focusTextInput.bind(this);
}
focusTextInput() {
// Explicitly focus the text input using the raw DOM API
// Note: we're accessing "current" to get the DOM node
this.textInput.current.focus();
}
render() {
// tell React that we want to associate the <input> ref
// with the `textInput` that we created in the constructor
return (
<div>
<input
type="text"
ref={this.textInput} />
<input
type="button"
value="Focus the text input"
onClick={this.focusTextInput}
/>
</div>
);
}
}
And I was Getting this Error -
TypeError: __WEBPACK_IMPORTED_MODULE_0_react___default.a.createRef is not a function
