Create array in cookie with javascript

Question

Is it possible to create a cookie using arrays?

I would like to store a[0]=\'peter\', a[\'1\']=\'esther\', a[\'2\']=\'john\' i

I agree with other comments - you should not be doing this and you should be using JSON. However, to answer your question you could hack this by storing the array as a comma-delimited string. Lets say you wanted to save a the following Javascript array into a cookie:

var a = ['peter','esther','john'];

You could define a cookie string, then iterate over the array:

// Create a timestamp in the future for the cookie so it is valid
var nowPreserve = new Date();
var oneYear = 365*24*60*60*1000; // one year in milliseconds
var thenPreserve = nowPreserve.getTime() + oneYear;
nowPreserve.setTime(thenPreserve);
var expireTime = nowPreserve.toUTCString();

// Define the cookie id and default string
var cookieId = 'arrayCookie';
var cookieStr = '';

// Loop over the array
for(var i=0;i

In this example, you would get the following cookie stored (if your domain is www.example.com):

arrayCookie=peter,ester,john;expires=1365094617464;domain=www.example.com
