Answer 1

Split (",") can convert Strings with commas into a String array, here is my code snippet.

    var input ='Hybrid App, Phone-Gap, Apache Cordova, HTML5, JavaScript, BootStrap, JQuery, CSS3, Android Wear API'
    var output = input.split(",");
    console.log(output);

["Hybrid App", " Phone-Gap", " Apache Cordova", " HTML5", " JavaScript", " BootStrap", " JQuery", " CSS3", " Android Wear API"]

Answer 2

For simple array members like that, you can use JSON.parse.

var array = JSON.parse("[" + string + "]");

---

This gives you an Array of numbers.

[0, 1]

If you use .split(), you'll end up with an Array of strings.

["0", "1"]

---

Just be aware that JSON.parse will limit you to the supported data types. If you need values like undefined or functions, you'd need to use eval(), or a JavaScript parser.

---

If you want to use .split(), but you also want an Array of Numbers, you could use Array.prototype.map, though you'd need to shim it for IE8 and lower or just write a traditional loop.

var array = string.split(",").map(Number);

Answer 3

Regexp

As more powerful alternative to split, you can use match

"0,1".match(/\d+/g)

let a = "0,1".match(/\d+/g)

console.log(a);

Answer 4

You can use javascript Spread Syntax to convert string to an array. In the solution below, I remove the comma then convert the string to an array.

var string = "0,1"
var array = [...string.replace(',', '')]
console.log(array[0])

Answer 5

Convert all type of strings

var array = (new Function("return [" + str+ "];")());



var string = "0,1";

var objectstring = '{Name:"Tshirt", CatGroupName:"Clothes", Gender:"male-female"}, {Name:"Dress", CatGroupName:"Clothes", Gender:"female"}, {Name:"Belt", CatGroupName:"Leather", Gender:"child"}';

var stringArray = (new Function("return [" + string+ "];")());

var objectStringArray = (new Function("return [" + objectstring+ "];")());

Result in console

Some practice doesnt support object strings

- JSON.parse("[" + string + "]"); // throw error

 - string.split(",") 
// unexpected result 
   ["{Name:"Tshirt"", " CatGroupName:"Clothes"", " Gender:"male-female"}", "      {Name:"Dress"", " CatGroupName:"Clothes"", " Gender:"female"}", " {Name:"Belt"",    " CatGroupName:"Leather"", " Gender:"child"}"]
