我的CHART_DATA是我的对象，我将其分配给chartData。 下面是我的updateData函数。这是我遇到的问题。在this.setState下，chartDataSelection不会从我的对象中获取数据。我不知道如何正确地从CHART_DATA对象中获取选择键。此代码下面是保存该对象的另一个js文件。
updateData(timeline) {
this.setState({
chartDataSelection: timeline
});
switch (timeline) {
case "one_month":
this.setState({
options: {
xaxis: {
min: new Date("28 Jan 2013").getTime(),
max: new Date("27 Feb 2013").getTime()
}
}
});
break;
case "six_months":
this.setState({
options: {
xaxis: {
min: new Date("27 Sep 2012").getTime(),
max: new Date("27 Feb 2013").getTime()
}
}
});
break;
case "one_year":
this.setState({
options: {
xaxis: {
min: new Date("27 Feb 2012").getTime(),

export default CHART_DATA;
答案 0 :(得分：1)
似乎您没有在告诉setState更新chartData（setState {chartData：{updatedData}}），而是创建了一个名为options的新状态对象。首先，您需要修改现有的charData。在这种情况下，我将其扩展到一个名为data的变量中。然后，使用新的xaxis修改数据，然后用更新的对象完全替换chartData。我只是为了示例而缩短了切换时间，但是您将不得不更新它们中的每一个。我希望这有帮助。
updateData(timeline) {
this.setState({
chartDataSelection: timeline
});
let data = {...d}
switch (timeline) {
case "one_month":
data.options.xaxis = {
min: new Date("28 Jan 2013").getTime(),
max: new Date("27 Feb 2013").getTime()
}
this.setState({chartData: data});
break;
default:
}
