Maximum update depth exceeded. code example
Example 1: 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.
import React, { Component } from 'react';
import styled from 'styled-components';
class Item extends React.Component {
constructor(props) {
super(props);
this.toggle= this.toggle.bind(this);
this.state = {
details: false
}
}
toggle(){
const currentState = this.state.details;
this.setState({ details: !currentState });
}
render() {
return (
<tr className="Item">
<td>{this.props.config.server}</td>
<td>{this.props.config.verbose}</td>
<td>{this.props.config.type}</td>
<td className={this.state.details ? "visible" : "hidden"}>PLACEHOLDER MORE INFO</td>
{<td><span onClick={this.toggle()}>Details</span></td>}
</tr>
)}
}
export default Item;
Example 2: 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.
when handle event,change this.toggle() to this.toggle or {()=> this.toggle()}
