将多维javascript数组转换为JSON?

What is the best way of converting a multi-dimensional javascript array to JSON?

将多维javascript数组转换为JSON的最佳方式是什么?

8 个解决方案

#1

Most of the popular JavaScript frameworks have JSON utility functions included. For instance, jQuery has a function that directly calls a url and loads the JSON result as an object : http://docs.jquery.com/Getjson

大多数流行的JavaScript框架都包含JSON实用函数。例如，jQuery有一个函数，它直接调用url并将JSON结果加载为一个对象:http://docs.jquery.com/Getjson。

However, you can get an open-source JSON parser and stringifier from the json website :

但是，您可以从JSON网站获得一个开源JSON解析器和stringifier:

Then, simply include the code and use the JSON.stringify() method on your array.

然后，只需包含代码并在数组中使用JSON.stringify()方法。

The "best" way has been provided by the other posters. If you don't need the full encoding features of the referenced libraries, and only need to encode simple arrays, then try this:

其他的海报也提供了“最佳”的方式。如果您不需要引用库的全部编码特性，只需要对简单数组进行编码，那么可以尝试以下方法:

<!DOCTYPE html>
<html>
<head>
<title>Simple functions for encoding Javascript arrays into JSON</title>
<script type="text/javascript">

window.onload = function() {
  var a = [
    [0, 1, '2', 3],
    ['0', '1', 2],
    [],
    ['mf', 'cb']
  ],
  b = [
    0, '1', '2', 3, 'woohoo!'
  ];
  alert(array2dToJson(a, 'a', '\n'));
  alert(array1dToJson(b, 'b'));
};

function array2dToJson(a, p, nl) {
  var i, j, s = '{"' + p + '":[';
  nl = nl || '';
  for (i = 0; i < a.length; ++i) {
    s += nl + array1dToJson(a[i]);
    if (i < a.length - 1) {
      s += ',';
    }
  }
  s += nl + ']}';
  return s;
}

function array1dToJson(a, p) {
  var i, s = '[';
  for (i = 0; i < a.length; ++i) {
    if (typeof a[i] == 'string') {
      s += '"' + a[i] + '"';
    }
    else { // assume number type
      s += a[i];
    }
    if (i < a.length - 1) {
      s += ',';
    }
  }
  s += ']';
  if (p) {
    return '{"' + p + '":' + s + '}';
  }
  return s;
}

</script>

Not sure I fully understand your question, but if you are trying to convert the object into a string of JSON then you probably want to look at the native JSON support in all the new browsers. Here's Resig's post on it. For browsers that don't yet support it try the json2.js library. JSON.stringify(obj) will convert your object to a string of JSON.

我不确定我是否完全理解您的问题，但是如果您试图将对象转换为JSON字符串，那么您可能需要查看所有新浏览器中的本机JSON支持。这是雷德里克的帖子。对于还不支持它的浏览器，可以使用json2。js库。stringify(obj)将把对象转换成JSON字符串。

This will convert all combinations of arrays within objects and vice versa including function names:

这将转换对象中所有数组的组合，反之亦然，包括函数名:

function isArray(a){var g=a.constructor.toString();
   if(g.match(/function Array()/)){return true;}else{return false;}
}
function objtostring(o){var a,k,f,freg=[],txt; if(typeof o!='object'){return false;}
   if(isArray(o)){a={'t1':'[','t2':']','isarray':true}
   }else         {a={'t1':'{','t2':'}','isarray':false}}; txt=a.t1;
   for(k in o){
           if(!a.isarray)txt+="'"+k+"':";
           if(typeof o[k]=='string'){txt+="'"+o[k]+"',";
           }else if(typeof o[k]=='number'||typeof o[k]=='boolean'){txt+=o[k]+",";
           }else if(typeof o[k]=='function'){f=o[k].toString();freg=f.match(/^function\s+(\w+)\s*\(/);
               if(freg){txt+=freg[1]+",";}else{txt+=f+",";};
           }else if(typeof o[k]=='object'){txt+=objtostring(o[k])+",";
           }
   }return txt.substr(0,txt.length-1)+a.t2;
}

You could use the encode function of this library.

您可以使用这个库的编码函数。

I've modified a bit the code previously provided... because a JSON has this format: [{"object":{"property_1":"value_1","property_2":"value_2"}}]

我对之前提供的代码做了一些修改……因为JSON的格式是:[{"object":{"property_1":"value_1"，"property_2":"value_2"}]

So, the code would be...

所以，代码是……

<!DOCTYPE html>

<head>
    <title>Simple functions for encoding Javascript arrays into JSON</title>
    <script type="text/javascript">

    window.onload = function(){
      var a = [['property_1','value_1'],['property_2', 'value_2']];
      alert("Comienzo..., paso ////"+a+"\\\\\\ a formato JSON");
      var jsonSerialized = array2dToJson(a, 'object');
      alert(jsonSerialized);
    };

    // Estructura de JSON [{"object":{"property_1":"value_1","property_2":"value_2"}}]

    function array2dToJson(a, p, nl) {
      var i, j, s = '[{"' + p + '":{';
      nl = nl || '';
      for (i = 0; i < a.length; ++i) {
        s += nl + array1dToJson(a[i]);
        if (i < a.length - 1) {
          s += ',';
        }
      }
      s += nl + '}}]';
      return s;

    function array1dToJson(a, p) {

use this code and very simple develop for more two array

使用此代码，并非常简单地开发更多的两个数组。

function getJSON(arrayID,arrayText) {    
    var JSON = "[";
    //should arrayID length equal arrayText lenght and both against null
    if (arrayID != null && arrayText != null && arrayID.length == arrayText.length) {
        for (var i = 0; i < arrayID.length; i++) {
            JSON += "{";
            JSON += "text:'" + arrayText[i] + "',";
            JSON += "id:'" + arrayID[i] + "'";
            JSON += "},";
        }
    }
    JSON += "]"
    JSON = Function("return " + JSON + " ;");
    return JSON();
}

and 3 array

和3组

function getJSON(arrayID, arrayText, arrayNumber) {
    var JSON = "[";  
    if (arrayID != null && arrayText != null && arrayNumber!=null && Math.min(arrayNumber.length,arrayID.length)==arrayText.length) {
        for (var i = 0; i < arrayID.length; i++) {
            JSON += "{";
            JSON += "text:'" + arrayText[i] + "',";
            JSON += "id:'" + arrayID[i] + "',";
            JSON += "number:'" + arrayNumber[i] + "'";
            JSON += "},";
        }
    }
    JSON += "]"
    JSON = Function("return " + JSON + " ;");
    return JSON();
}
