当我想将数组转换为 JSON 时，下面的代码有问题。请在下面查看我的代码：

<html>

<head>
</head>

<body style="text-align:center;" id="body">
  <p id="GFG_UP1" style="font-size: 16px;">

  </p>
  <p id="GFG_UP2" style="font-size: 16px;">
  </p>
  <button onclick="gfg_Run()">
    Convert
  </button>
  <p id="GFG_DOWN1" style="color:red;
    font-size: 20px; font-weight: bold;">
  </p>
  <p id="GFG_DOWN2" style="color:red;
    font-size: 20px; font-weight: bold;">
  </p>
  <script>
    var el_up1 = document.getElementById("GFG_UP1");
    var el_up2 = document.getElementById("GFG_UP2");
    var el_down1 = document.getElementById("GFG_DOWN1");
    var el_down2 = document.getElementById("GFG_DOWN2");
    var array1 = [34, 24, 31, 48];
    var array2 = [23, 43, 65, 52];
    var numberArray1 = [];
    var numberArray2 = [];
    for (i = 0; i < array1.length; i++) {
      numberArray1[i] = "number" + i + ':' + array1[i];
    }
    el_up1.innerHTML = "Array = [" + array1 + "]";;
    function gfg_Run() {
      el_down2.innerHTML =
        JSON.stringify(Object.assign(numberArray1));
    }

    for (i = 0; i < array2.length; i++) {
      numberArray2[i] = "number" + i + ':' + array2[i];
    }
    el_up2.innerHTML = "Array = [" + array2 + "]";;
    function gfg_Run() {
      el_down2.innerHTML =
        JSON.stringify(Object.assign(numberArray2));
    }
  </script>
</body>

</html>

正在给出输出：

["number0:23","number1:43","number2:65","number3:52"]

不是两个数组都被转换

就像它应该同时提供输出：

["number0:34","number1:24","number2:31","number3:48"]
["number0:23","number1:43","number2:65","number3:52"]
