在Javascript中修改JSON数组

Question

Hyperlink

我想要json数组，例如唯一的this数组，并在其中创建价格数组，如quoteId匹配的

输出

MyJsonArray = 
[{quoteId: "MqWmJkUzcP", price: 211, userName: "Test"},{quoteId: "OqgFavcIiR", price: 230, userName: "Aglowid"},{quoteId: "MqWmJkUzcP", price: 120},
 {quoteId: "IFeiWnxMfq", price: 146, userName: "Test-2"},
 {quoteId: "pVL0CgIxaN", price: 155, userName: "Test-2"}]

很抱歉键入和语法错误，因为我从手机上问了这个问题

这是您使用纯JavaScript（es6）的方式

const mergePrice = data => data.reduce((result, val) => {
   const { quoteId, price, userName } = val;
   let obj = result.find(o => o.quoteId === quoteId);
   if (!obj) {
       obj = { quoteId, userName, price: [] };
       result.push(obj);
   }
   obj.price.push(price);
   return result;
}, []);

const merged = mergePrice([{quoteId: "MqWmJkUzcP", price: 211, userName: "Test"},{quoteId: "OqgFavcIiR", price: 230, userName: "Aglowid"},{quoteId: "MqWmJkUzcP", price: 120},
 {quoteId: "IFeiWnxMfq", price: 146, userName: "Test-2"},
 {quoteId: "pVL0CgIxaN", price: 155, userName: "Test-2"}]);
 
 console.log(merged);
