Parse JSON array from string

Question

I want to convert the following string to an array

var string = '["YES","NO"]';

How do I do this?

• Roli Agrawal: is array object == array of objects
• Maciej Baranowski: Convert string to array? This is already array. Describe your problem in details and tell us what you tried
• Sriya: This is not a array. This is string. This is what i got first into my javascript Object {1: "["YES","NO"]"} And now i want to convert this keys value("["YES","NO"]") into array

Answer 1

use the global JSON.parse method

JSON.parse('["YES","NO"]'); // returns ["YES", "NO"]

You can also use the JSON.stringify method to write the array back to a string if thats how you are storing it.

JSON.stringify(["YES", "NO"]); // returns '["YES", "NO"]'

• Michael Geary: And the improved readability is the least important thing about it.

Answer 2

var str= '["YES","NO"]';
var replace= str.replace(/[\[\]]/g,'');
var array = replace.split(',');

• Michael Geary: alert( "YES".length ); alert( array[0].length );
• Michael Geary: var str= '["Are you [[sure?]]","No, not really"]';
• Omar Dulaimi: I would add a .filter(Boolean) after the split to remove empty string values.

Answer 3

You can also use $.parseJSON:

var string = '["YES","NO"]';
var array = $.parseJSON(string);
