我已经编写了这段代码，目前正在处理onClick事件中的错误。我有两个事件，子元素上的onClick事件和顶级父元素上的onChange事件。

预期的行为应该是更改当前在Container组件中保存的activeAccount变量。为此，我在AccountRow组件上添加了一个onClick处理程序，然后应调用顶级父级的onChange函数。

但是，线

'this.props.onChange(this.props.account)',

在

handleClick: function(e) {
        this.props.onChange(this.props.account);
    },

旨在使用参数“ this.props.account”调用父函数，

给我这个错误：

Uncaught TypeError: this.props.onChange is not a function.

我最初以为这是一个范围问题，但是我添加了

{...this.props}

在父容器组件内的每个子项和嵌套子项上。因此，所有道具都应向下传播到AccountRow组件。但是，问题仍然存在。

    var ACCOUNTS = [
    {name: 'cash on hand'},
    {name: 'savings account'},
    {name: 'shared account'},
    {name: 'my second wallet'}
];

var TRANSACTIONS = [
    {date: '', name: 'Bananas', amount: 6, category: 'Groceries', account: 'cash on hand'},
    {date: '', name: 'Apples', amount: 2.50, category: 'Groceries', account: 'cash on hand'},
    {date: '', name: 'Cash withdrawal', amount: 250, account: 'savings account'}
];
