你如何從 JavaScript 的控制台 output 中去掉“name”和“count”的雙引號？

Question

我在轉動輸入時遇到問題：

["apple", "banana", "carrot", "durian", "eggplant", "apple", "carrot"] 右轉output：

[{ name: "Apple", count: 2 }, { name: "Banana", count: 1 }, { name: "Carrot", count: 2 }, { name: "Durian", count: 1 }, { } name: "Eggplant", count: 1 }], 我這里遇到錯誤 output:

[{"name":"Apple","count":2},{"name":"Banana","count":1},{"name":"Carrot","count":2},{ “名稱”：“榴蓮”，“計數”：1}，{“名稱”：“茄子”，“計數”：1}]。 我怎樣才能擁有正確的output：

[{ name: "Apple", count: 2 }, { name: "Banana", count: 1 }, { name: "Carrot", count: 2 }, { name: "Durian", count: 1 }, { } name: "Eggplant", count: 1 }] 使用 console.log() 方法？

    <html>
    <body>
    <script>
    var input = ["apple", "banana", "carrot", "durian", "eggplant", "apple", "carrot"];
    
    var A = 0;//to count the number of apples
    var B = 0;//to count the number of bananas
    var C = 0;//to count the number of carrots
    var D = 0;//to count the number of durians
    var E = 0; //to count the number of eggplants

     for (var i = 0; i < input.length; i++)
      {
         if (input[i] == "apple")
         {   
           A += 1;  
          }
         if (input[i] == "banana")
         {   
           B += 1;  
          }
         if (input[i] == "carrot")
         {   
           C += 1;  
          }
         if (input[i] == "durian")
         {   
           D += 1;  
         }
         if (input[i] == "eggplant")
         {   
           E += 1;  
         }
       }            

    let x1 = { name: 'Apple', 
               count: A };
    let x2 = { name: 'Banana', 
               count: B };
    let x3 = { name: 'Carrot', 
               count: C };
    let x4 = { name: 'Durian', 
               count: D };
    let x5 = { name: 'Eggplant', 
               count: E };

   var output = [];
   output.push(x1);
   output.push(x2);
   output.push(x3);
   output.push(x4);
   output.push(x5);

   console.log("output = ", output);
   document.getElementById('output').innerHTML = JSON.stringify(output);

   </script>
   </body>
   </html>

Answer 1

您可以使用如下正則表達式：

var yourStringifiedResult = "[{\"name\":\"Apple\",\"count\":2},{\"name\":\"Banana\",\"count\":1},{\"name\":\"Carrot\",\"count\":2},{\"name\":\"Durian\",\"count\":1},{\"name\":\"Eggplant\",\"count\":1}]";

yourStringifiedResult = yourStringifiedResult.replace(/"(\w+)"\s*:/g, '$1:');
console.log(yourStringifiedResult);

工作樣本：

 var yourStringifiedResult = "[{\"name\":\"Apple\",\"count\":2},{\"name\":\"Banana\",\"count\":1},{\"name\":\"Carrot\",\"count\":2},{\"name\":\"Durian\",\"count\":1},{\"name\":\"Eggplant\",\"count\":1}]"; yourStringifiedResult = yourStringifiedResult.replace(/"(\w+)"\s*:/g, '$1:'); console.log(yourStringifiedResult);

Answer 2

只需在推送數組中的所有對象后添加此行：

let outputInString = "";

for (let fruit of input) outputInString += "Name: " + fruit.name + ", Count: " + fruit.count + ", ";

document.getElementById('output').innerHTML = outputInString;
