I want to do in class component what I did in function component, but it gives an error. How can I fix?
function component:
const [listBtnClassName, setListBtnClassName] = useState("listBtnPulse");
useEffect(() => {
if (showGrid) {
setListBtnClassName("listBtnPulseNone");
}
}, [showGrid]);
<PageFilter listBtnClassName={listBtnClassName} ></PageFilter>class component:
this.state = {
listBtnClassName: "listBtnPulse",
};
componentDidUpdate() {
if (this.props.showGrid) {
this.setState({ listBtnClassName: "listBtnPulseNone" });
}
}
<PageFilter listBtnClassName={this.state.listBtnClassName} ></PageFilter>Error: Maximum update depth exceeded. This can happen when a component repeatedly calls setState inside componentWillUpdate or componentDidUpdate. React limits the number of nested updates to prevent infinite loops.
You need to make sure the showGrid from the previous props is not true, but the showGrid from current props is true.
See this document for more information.
this.state = {
listBtnClassName: "listBtnPulse",
};
componentDidUpdate(prevProps) {
if (!prevProps.showGrid && this.props.showGrid) {
this.setState({ listBtnClassName: "listBtnPulseNone" });
}
}<PageFilter listBtnClassName={this.state.listBtnClassName} ></PageFilter>
