const arr = {
fields: {
market: {
data: [
{ name: 'isHk', value: true},
{ name: 'isOvs', value: false },
],
},
},
};
要求是：在market中的data里的value筛选出value是true的，只要data里的value有一个是true，就返回'market'这个字符串，如果data里都是false，则返回空
<script>
const arr = {
fields: {
market: {
data: [
{ name: 'isHk', value: true },
{ name: 'isOvs', value: false },
],
},
},
};
var value = arr.fields.market.data.filter(i => i.value === true).length ? 'market' : ''
alert(value)
