How to convert string to Array via javascript?

Question

I have following string in javascript variable

var days="1,2,3";

now I want this in following way as javascript variable with JSON format like

jdays=["1", "2", "3"];

Is there anyway to do so?

• Tushar: You want to remove 3? Try days.split(',');, or days.match(/\d+/g)
• Oleksandr T.: jdays = days.split(',') ?
• skiskd: @Tushar - no I don't want to remove 3, I have updated my question.please let me know if any solution.
• A. Wolff: That has nothing to do with json...
• Tushar: @skiskd That is not JSON, it'a an array, check my previous comment to get the data in the array format

Answer 1

This will work

var days = "1,2,3",
 jdays = days.split(',');
console.log(jdays); // ["1", "2", "3"]

String.prototype.split() is used to split a string into an array by removing every instance of the string passed to it as a parameter and pushing each fragment of the string to the array.

The array created by String.prototype.split() is the return value of the function.

• Tushar: FYI console.log(jdays); // [1, 2, 3] is wrong, jdays will be ["1", "2", "3"], note that the elements of array are strings not numbers
• Oliver: @Tushar Didn't see that... Thanks.

Answer 2

by using split function you can do this

 var daysArr = days.split(',') 

Answer 3

If, when you say you "want this in following way as a javascript variable" you mean you want that JSON format string in a variable.. then..

jsonstring = 'jdays='+JSON.stringify(days.split(','));
