React components can be hidden or shown without causing re-renders by using the CSS property "display" to toggle the visibility of the component. Instead of changing the component's state, this approach manipulates the CSS style. This way, the component is not re-rendered, and it remains in the virtual DOM.
Here's an example:
class MyComponent extends React.Component {
constructor(props) {
super(props);
this.state = {
visible: true
};
}
toggleVisibility() {
this.setState(prevState => ({ visible: !prevState.visible }));
}
render() {
const { visible } = this.state;
return (
<div>
<button onClick={() => this.toggleVisibility()}>
Toggle visibility
</button>
<div
style={{ display: visible ? "block" : "none" }}
>
Hidden content
</div>
</div>
);
}
}
In this example, the div
element with the "Hidden content" text is hidden or shown depending on the current value of the visible
state property. The style of the div
element is changed using the inline style {{display: visible ? "block" : "none"}}
. When the user clicks on the "Toggle visibility" button, the toggleVisibility
method is called, which updates the visible
state property. However, the component doesn't re-render because only the style of the div
element changes.
