Uncaught Invariant Violation: 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.
这个错查了一下，说是超出最大更新深度。当组件在componentWillUpdate或componentDidUpdate中重复调用setState时，可能会发生这种情况。React限制嵌套更新的数量以防止无限循环。
错误代码：
<div className="tableBody"> {equipmentsList && equipmentsList.map((item, index) => { return <div key={index}> <div className="tableTd">{index+1}</div> <div className="tableTd equipmentTd" onClick={this.showDetails(item.equipmentNum)}>{item.equipmentName}</div> </div>; }) } </div>
showDetails = (equipmentNum) => { this.setState({ detailVisible: true, equipmentNum }) }
问题就出现在
onClick={this.showDetails(item.equipmentNum)}
正常写法：
onClick={() => this.showDetails(item.equipmentNum)}
加上一个（）=> 就可以了
Uncaught Invariant Violation: Maximum update depth exceeded.
