How to convert two dimensional array to JSON

[livinglegends]

Hi,

I need to convert two dimensional array to JSON.

I can convert 1-d array to JSON but not 2-d array.

Below is the code I have written.


var foodArray = new Array();
var key = "custodian";
var obj = {};
foodArray[key] = ['Dal', 'abc'];
obj.val = foodArray;
key = "doc";
foodArray[key] = ['Dal1', 'abc1'];
obj.val = foodArray;
key = "lang";
foodArray[key] = ['Dal2', 'abc2'];

obj.val = foodArray;

var foodJson = Ext.encode(obj);
console.log(foodJson);Can anyone give idea?

In javascript or in your server language?

Maybe an example of your data and a description of your desired output would help?

[livinglegends]

In javascript.. I have updated my previous post with code which I am using.

[Condor]

Arrays have Numbers as keys, Objects have Strings as keys.

So in your example, foodArray shouldn't be an Array at all, it should be an Object.

[livinglegends]

it will be quite difficult now to convert it from Array to object as it is being used at so many places.

Is there any workaround to convert ?

[Condor]

No, there isn't.

Also, you should not be using new Array or new Object.

You could use:

var foodArray = {};
foodArray["custodian"] = ['Dal', 'abc'];
foodArray["doc"] = ['Dal1', 'abc1'];
foodArray["lang"] = ['Dal2', 'abc2'];
obj = {};
obj.val = foodArray;
or even:

obj = {
val: {
custodian: ['Dal', 'abc'],
doc: ['Dal1', 'abc1'],
lang: ['Dal2', 'abc2']
}
};

No, there isn't.

You could use:

var foodArray = {};
foodArray["custodian"] = ['Dal', 'abc'];
foodArray["doc"] = ['Dal1', 'abc1'];
foodArray["lang"] = ['Dal2', 'abc2'];
obj = {val: foodArray};or even:

obj = {
val: {
custodian: ['Dal', 'abc'],
doc: ['Dal1', 'abc1'],
lang: ['Dal2', 'abc2']
}
};
