根據(jù)屬性過濾物件陣列
問題:
你有一個真實(shí)的數(shù)組房地產(chǎn)對象並希望根據(jù)特定屬性(例如價(jià)格、平方英尺、床位數(shù)量和數(shù)量)對其進(jìn)行過濾
解決方案:
要過濾數(shù)組,可以使用Array.prototype.filter
代碼:
var newArray = homes.filter(function(el) { return el.price <= 1000 && el.sqft >= 500 && el.num_of_beds >= 2 && el.num_of_baths >= 2.5; });
說明:
每個過濾器方法採用一個測試每個過濾器方法都採用一個測試元素的回調(diào)函數(shù)在數(shù)組中。如果測試傳回 true,則該元素將包含在新數(shù)組中。在這種情況下,回呼函數(shù)會檢查 home 物件是否符合指定條件,如果滿足則傳回 true。
實(shí)例:
var obj = { 'homes': [{ "home_id": "1", "price": "925", "sqft": "1100", "num_of_beds": "2", "num_of_baths": "2.0", }, { "home_id": "2", "price": "1425", "sqft": "1900", "num_of_beds": "4", "num_of_baths": "2.5", }, // ... (more homes) ... ] }; // (Note that because `price` and such are given as strings in your object, // the below relies on the fact that <= and >= with a string and number // will coerce the string to a number before comparing.) var newArray = obj.homes.filter(function(el) { return el.price <= 1000 && el.sqft >= 500 && el.num_of_beds >= 2 && el.num_of_baths >= 1.5; // Changed this so a home would match }); console.log(newArray);
以上是如何根據(jù)屬性過濾房地產(chǎn)家庭物件數(shù)組?的詳細(xì)內(nèi)容。更多資訊請關(guān)注PHP中文網(wǎng)其他相關(guān)文章!

在JavaScript中,選擇單行註釋(//)還是多行註釋(//)取決於註釋的目的和項(xiàng)目需求:1.使用單行註釋進(jìn)行快速、內(nèi)聯(lián)的解釋;2.使用多行註釋進(jìn)行詳細(xì)的文檔說明;3.保持註釋風(fēng)格的一致性;4.避免過度註釋;5.確保註釋與代碼同步更新。選擇合適的註釋風(fēng)格有助於提高代碼的可讀性和可維護(hù)性。
