我有以下 JavaScript 数组:
supportedCurrencies = [
{
"currencyCode":"USD",
},
{
"currencyCode":"CAD",
},
{
"currencyCode":"GBP",
}
]
我的目标是获取currencyCode值并创建一个数组(例如[USD、CAD、GBP...]，然后用|连接这些数组...以获得最终字符串输出USD|CAD|GBP
supportedCurrencies.map(key => {
// Map through JS object
// Get currencyCode values
// Create new array with values
// Join these values with |
})
最佳答案
supportedCurrencies = [
{
"currencyCode":"USD",
},
{
"currencyCode":"CAD",
},
{
"currencyCode":"GBP",
}
]
const info = supportedCurrencies.map(el => el.currencyCode).join("|")
