Convert array to JSON
Solution 1:
Script for backward-compatibility: https://github.com/douglascrockford/JSON-js/blob/master/json2.js
And call:
var myJsonString = JSON.stringify(yourArray);
Note: The JSON object is now part of most modern web browsers (IE 8 & above). See caniuse for full listing. Credit goes to: @Spudley for his comment below
Solution 2:
I made it that way:
if I have:
var jsonArg1 = new Object();
jsonArg1.name = 'calc this';
jsonArg1.value = 3.1415;
var jsonArg2 = new Object();
jsonArg2.name = 'calc this again';
jsonArg2.value = 2.73;
var pluginArrayArg = new Array();
pluginArrayArg.push(jsonArg1);
pluginArrayArg.push(jsonArg2);
to convert pluginArrayArg (which is pure javascript array) into JSON array:
var jsonArray = JSON.parse(JSON.stringify(pluginArrayArg))

Wow, seems it got a lot easier nowadays... 3 ways you can do it:
json = { ...array };
json = Object.assign({}, array);
json = array.reduce((json, value, key) => { json[key] = value; return json; }, {});

I decided to use the json2 library and I got an error about “cyclic data structures”.
I got it solved by telling json2 how to convert my complex object. Not only it works now but also I have included only the fields I need. Here is how I did it:
OBJ.prototype.toJSON = function (key) {
var returnObj = new Object();
returnObj.devid = this.devid;
returnObj.name = this.name;
returnObj.speed = this.speed;
returnObj.status = this.status;
return returnObj;
}
