这种的怎么对比.. 求解答
var obj = {"ea":{"rx":"69818600","tx":"9990333"},"eb":{"rx":"0","tx":"0"}};

Answer 1

var obj = {"ea":{"rx":"69818600","tx":"9990333"},"eb":{"rx":"0","tx":"0"}};
function getMaxValue(obj, key) {
    var values = Object.values(obj);
    return values.sort(function(a, b) {
        return +b[key] - +a[key]; 
    })[0];
}
console.log(getMaxValue(obj, "rx"));
console.log(getMaxValue(obj, "tx"));

Answer 2

1.obj.ea.rx > obj.eb.rx;
2.obj.ea.tx > obj.eb.tx;
是要这个吗
