Convert a multidimensional javascript array to JSON?

Question

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

Answer 1

use this code and very simple develop for more two array

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

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();
}

Answer 2

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

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;
}

Answer 3

var t = {}

for(var i=0;i<3;i++) {
    var _main = {};
    var _dis = {}
    var _check = {};

    _main["title"] = 'test';
    _main["category"] = 'testing';
    _dis[0] = '';
    _dis[1] = '';
    _dis[2] = '';
    _dis[3] = '';
    _check[0] = 'checked';
    _check[1] = 'checked';
    _check[2] = 'checked';
    _check[3] = 'checked';
    _main['values'] = _check;
    _main['disabled'] = _dis;
    t[i] = _main;
}

alert(JSON.stringify(t));
