Tuan-tuan, tolonglah saya.
exchange.IO("api", "GET","/fapi/v1/ticker/24hr")
Bagaimana dengan kontrak-kontrak terdahulu yang mempunyai kadar perubahan harga (priceChangePercent) yang paling tinggi selepas mendapat maklumat mengenai perubahan harga kontrak selama 24 jam?
Ini kira-kira hasilnya.

function compare(property) {
return function(obj1, obj2) {
var value1 = obj1[property];
var value2 = obj2[property];
return value2 - value1; // 降序排列
}
}
function main{
exchange.IO("api", "GET","/fapi/v1/ticker/24hr").sort(compare("priceChangePercent"));
}
得到的结果是按照价格变动从大到小排列的
