我有一个对象数组,其中包含一些变量信息,但还有另一个对象数组,其中包含一些更多信息。 我正在尝试显示一个显示初始数组的表,并且当用户单击该特定对象的行时,它将呈现一个新表,其中选定了该特定数组内的对象。
startCreateEventHandler = () => {
this.setState({ creating: true });
};
modalCancelHandler = () => {
this.setState({ creating: false });
};
render() {
return (
<div>
{this.state.creating && (
<Table>
<thead>
<tr>
<th>Details</th>
</tr>
</thead>
<tbody>
{this.props.archives.map(archive =>
archive.ticketRequests.map(request => (
<tr>
<td>{request.details}</td>
</tr>
))
)}
</tbody>
</Table>
)}
{this.state.creating ? null : (
<Table hover className="table table-striped">
<thead>
<tr>
<th>Title</th>
</tr>
</thead>
<tbody>
{this.props.archives.map(archive => (
<tr onClick={this.startCreateEventHandler}>
<td>{archive.title}</td>
</tr>
))}
</tbody>
</Table>
)}
</div>
);
}
我得到的是正确设置的表,但是一旦我单击一行,它就会在下一个表中显示所有*行对象,而不仅仅是该特定存档。

如果我了解您的问题,那么您还需要将当前单击的存档设置为状态,并需要解析所选的存档
startCreateEventHandler = (archive) => {
this.setState({ creating: true, selectedArchive: archive });
};
modalCancelHandler = () => {
this.setState({ creating: false, selectedArchive: undefined });
};
render() {
return (
<div>
{this.state.creating && (
<Table>
<thead>
<tr>
<th>Details</th>
</tr>
</thead>
<tbody>
{this.state.selectedArchive.map(archive =>
<tr>
<td>{archive.details}</td>
</tr>
)}
</tbody>
</Table>
)}
{this.state.creating ? null : (
<Table hover className="table table-striped">
<thead>
<tr>
<th>Title</th>
</tr>
</thead>
<tbody>
{this.props.archives.map(archive => (
<tr onClick={(event)=>this.startCreateEventHandler(archive.ticketRequests)}>
<td>{archive.title}</td>
</tr>
))}
</tbody>
</Table>
)}
</div>
);
};
