]我試圖弄清楚如何根據它們的位置是美國還是加拿大以及按地區（東、西、南）過濾掉陣列中的所有物件。
例如，如果我想要東部的所有加拿大城市，它將回傳索引為 1,4,6 的物件。您將如何根據兩個引數過濾掉陣列中的位置字串，它們是否包含美國或加拿大以及東、西、南。
uj5u.com熱心網友回復：
希望下面的例子能讓你走上正軌
假設：您的陣列存盤在名為data的變數中
var searchString = "American";
var filteredData = data.filter((item) => {
return item.location.includes(searchString);
});
for (var i = 0; i < filteredData.length; i ) {
console.log(filteredData[i].location);
}
