JS implementation example of converting a two-dimensional array into a json format string operation

This article describes the JS implementation of converting a two-dimensional array into a json format string operation. Share it for your reference, as follows:

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>json</title>
  <script src="/jquery/2.0.0/"></script>
  <script>
  $(function(){
    /******Transfer of two-dimensional array***************/
    //Define array    var arr=new Array();
    arr =[[1,2],[1,2],[1,2],[1,2]]; //Initialize a two-dimensional array    var i,j;
    for(i=0;i<;i++){
      var arr_l=new Array();//Get a one-dimensional array in a two-dimensional array      arr_1=arr[i];
      //Transfer through one-dimensional array      for(j=0;j<arr_1.length;j++){
        //alert(arr_1[j]); // arr_1: represents the value in a single array        (arr_1[j]);
      }
    }
    ("<br>");
    var array = [[10, 100, 1000], [1000, 100, 10]];
    // encodeArray2D method    var jsonStr = encodeArray2D(array);
    //alert(jsonstr);
    (jsonStr);
    ("<br>");
    // arrayToJson method    var jsonStr2 = arrayToJson(array);
    (jsonStr2);
  });
  /**
   * Convert a 2D array to a json string
   */
  function encodeArray2D(obj) {
    var array = [];
    for (var i = 0; i < ; i++) {
      array[i] = '[' + obj[i].join(',') + ']';
    }
    return '[' + (',') + ']';
  }
  /**
   * Convert a 2D array to a json string
   */
  function arrayToJson(o) {
    var r = [];
    if (typeof o == "string") return "\"" + (/([\'\"\\])/g, "\\$1").replace(/(\n)/g, "\\n").replace(/(\r)/g, "\\r").replace(/(\t)/g, "\\t") + "\"";
    if (typeof o == "object") {
      if (!) {
        for (var i in o)
        (i + ":" + arrayToJson(o[i]));
        if (!! && !/^\n?function\s*toString\s*\{\n?\s*\[native code\]\n?\s*\}\n?\s*$/.test()) {
        ("toString:" + ());
        }
        r = "{" + () + "}";
      } else {
        for (var i = 0; i < ; i++) {
        (arrayToJson(o[i]));
        }
        r = "[" + () + "]";
      }
      return r;
    }
    return ();
  }
</script>
</head>
<body>
</body>
</html>

useOnline HTML/CSS/JavaScript code running tool：http://tools./code/HtmlJsRunThe test run results are as follows:

12121212
[[10,100,1000],[1000,100,10]]
[[10,100,1000],[1000,100,10]]
