这是我的 JSON 数据
var data = [{
meal_com_id: "1",
company_name: "PeryCap",
pic: "https://shopgo.in/upload/1545849409-1518284057-Untitled-nn1.png",
status: "1",
details: "sdvaebfvhjaebfber itnwiuore tg5ykrgt wiretgi34 tgi3rgtiquogtiq",
Address:
"B.L. Behind Dhaldighi Petrol Pump, Burdwan, B.L.Hati Rd, Khosbagan Burdwan West Bengal 713101",
day_meal: "42",
night_meal: "25"
}];
如何使用 javascript 从中选取特定数据
var day_meal= data.day_meal;
最佳答案
给定的数据是 JSON 的字符串化形式，因此您首先需要对其进行解析以获取实际数组，并且由于该数组有一个对象，您可以访问索引为 0 的对象，然后访问 day_meal该对象的属性:
var data = '[{"meal_com_id":"1","company_name":"PeryCap","pic":"https://shopgo.in/upload/1545849409-1518284057-Untitled-nn1.png","status":"1","details":"sdvaebfvhjaebfber itnwiuore tg5ykrgt wiretgi34 tgi3rgtiquogtiq","Address":"B.L. Behind Dhaldighi Petrol Pump, Burdwan, B.L.Hati Rd, Khosbagan Burdwan West Bengal 713101","day_meal":"42","night_meal":"25"}]';
var dayMeal = JSON.parse(data)[0].day_meal;
console.log(dayMeal);关于javascript - 如何从 JSON 值中选取数据，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/55825301/
