从 JS 映射获取第一个值

Question

>我有这个代码通过一个JS对象数组映射

marketplaceData.map((marketplace) => {
const { primarySaleCount, secondarySaleCount } = marketplace;
console.log(primarySaleCount);
})

返回值：

primarySaleCount -> 905, 459
secondarySaleCount -> 394, 291

我只想抓取其中一个对象，然后像这样单独显示它们：

<Chart
data={[
[
"Platform 1",
parseInt(primarySaleCount),   //desiredValue -> 905. //actualValue ->905
parseInt(secondarySaleCount), //desiredValue -> 394.  //actualValue ->392
],
[
"Platform 2",
parseInt(primarySaleCount), //desiredValue -> 459.   //actualValue -> 905
parseInt(secondarySaleCount), //desiredValue ->291.  //actualValue ->394
],
]}
/>

基本上，我的市场数据映射的返回值在 primarySaleCount 变量中为我提供了两个字符串。我希望以某种方式将返回的两个主要销售计数字符串分开，以便我可以在 (同样的事情也适用于 secondarySaleCount(

谢谢

Answer 1

primarySaleCount -> "905, 459"
secondarySaleCount -> "394, 291"
var primarySaleCountNumbers = primarySaleCount.split(','); //this will give you an array ['905', '459']
var secondarySaleCountNumbers= secondarySaleCount.split(',') //this will give you an array ['394', '291']

你可以像这样在你的平台中传递这些，

parseInt(primarySaleCountNumbers[0]) //To pass 905 wherever you want
parseInt(primarySaleCountNumbers[1]) //To Pass 459 

同样适用于secondarySaleCount

<Chart
data={[
[
"Platform 1",
parseInt(primarySaleCountNumbers[0]),   
parseInt(secondarySaleCountNumbers[0]), 
],
[
"Platform 2",
parseInt(primarySaleCountNumbers[1]), 
parseInt(secondarySaleCountNumbers[1]),
],
]}
/>
