如何將JavaScript中的嵌套數組轉換為json結構

Question

在下面的代碼中，我試圖填充javascript類，這樣我得到一個可以字符串化為json字符串的對象。

       function classValue(valuearrs) {
        for (var i = 0; i < valuearrs.length; i++) {
            for (j = 0; j < valuearrs[i].length; j++) {

                this.id = valuearrs[i][j];
                this.name = valuearrs[i][j];
                this.somekey = valuearrs[i][j];
            }
        }
  }


   function CreatenestedarrObj( valuearr) {

        this.Arrayparameters = [new classValue (valuearr)];
    }

   function ArrayMethodCall() {

       var valuearr = new Array();
       valuearr[0] = "myval1";
       valuearr[1] = "myval2";
       valuearr[2] = "myval3";
       var valuearr1 = new Array();
       valuearr1[0] = "myval11";
       valuearr1[1] = "myval12";
       valuearr1[2] = "myval13";
       nestedarr = new Array();
       nestedarr[0] = valuearr;
       nestedarr[1] = valuearr1;

       var x = new CreatenestedarrObj( nestedarr);
       var strobject = JSON.stringify(x);
       alert(strobject);
   }

   </script>
  </head> <body> MethodCall: <input type="button" value="Call Method" onclick=" ArrayMethodCall ()" />

字符串化后，期望值是{ArrayParameters：[{myval1，myval2，myval3}，{myval1，myval12，myval13}]}}。我可以認為我缺少的東西是每次在循環中創建一個新對象，但是如何？ 否則我可能完全錯了。任何幫助將不勝感激。

Answer 1

嘗試這個

    function classValue(valuearrs) {
        var arr = []
        for (var i = 0; i < valuearrs.length; i++) {
            for (j = 0; j < valuearrs[i].length; j++) {
                var temp = new Object();
                temp.id = valuearrs[i][j];
                temp.name = valuearrs[i][j];
                temp.somekey = valuearrs[i][j];
                arr[j] = temp;
            }
        }
        return arr;
  }

Answer 2

更改此：

function classValue(valuearrs) {
        var arr=[]
          for (var i = 0; i < valuearrs.length; i++) {
              arr[i]={};
            for (j = 0; j < valuearrs[i].length; j++) {

                arr[i].id = valuearrs[i][j];
                arr[i].name = valuearrs[i][j];
                arr[i].somekey = valuearrs[i][j];
            }
        }
          return arr;
  }

Answer 3

我不知道為什么需要將nestedarr拆分為id ， name和somekey但是如果不需要，只需返回valuearrs ，就可以了：

function classValue(valuearrs) {
    return valuearrs;
  }


   function CreatenestedarrObj( valuearr) {

        this.Arrayparameters = [new classValue (valuearr)];
    }

   function ArrayMethodCall() {

       var valuearr = new Array();
       valuearr[0] = "myval1";
       valuearr[1] = "myval2";
       valuearr[2] = "myval3";
       var valuearr1 = new Array();
       valuearr1[0] = "myval11";
       valuearr1[1] = "myval12";
       valuearr1[2] = "myval13";
       nestedarr = new Array();
       nestedarr[0] = valuearr;
       nestedarr[1] = valuearr1;

       var x = new CreatenestedarrObj( nestedarr);
       var strobject = JSON.stringify(x);
       console.info(strobject);
   }

輸出是

{"Arrayparameters":[[["myval1","myval2","myval3"],["myval11","myval12","myval13"]]]}

如果您不希望將其用作Arrayparameters ，則可以Arrayparameters ，或者可以使用以下代碼

var strobject = JSON.stringify(nestedarr);

和輸出將是這樣的：

[["myval1","myval2","myval3"],["myval11","myval12","myval13"]]
