Question

I have a problem with javascript cookies that I have been struggling with for days.
I have this function(almost the same from w3):

function getCookie(c_name)
{   
var i,x,y,ARRcookies=document.cookie.split(";");
for (i=0;i<ARRcookies.length;i++)
{
  x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
  y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
  x=x.replace(/^\s+|\s+$/g,"");
  if (x.indexOf(c_name)==0)
    {
     ar[i]=y;
     arr[i]=x;
    }
  }
}

Lets say that I have stored two cookies with the following names:tablet1 and taskt1. When I call getCookie('table'), ar.length is 1. After that I run getCookie('task') and ar.length is 2. This causes me a lot of problems. If I put ar=0; at the start of the function nothing works, it’s like the function just stores values every time I call it without erasing the old ones.

============================

var arrCookies = {};
function getCookie(c_name)
{   
var i,x,y,ARRcookies=document.cookie.split(";");
for (i=0;i<ARRcookies.length;i++)
{

  x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
  y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
  x=x.replace(/^\s+|\s+$/g,"");
  if (x.indexOf(c_name)==0)
    {
        arrCookies[c_name] = y;

    }
  }
}

when i do that the arrCookies[c_name] it does not store any values–>arrCookies[c_name].lenght is zero

=================================================
i also did

function getCookie(c_name)
{   
var i,x,y,ARRcookies=document.cookie.split(";");
for (i=0;i<ARRcookies.length;i++)
{

  x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
  y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
  x=x.replace(/^\s+|\s+$/g,"");
  if (x.indexOf(c_name)==0)
    {
        if(c_name=='table'){
            xxx[i]=x;
            xx[i]=y;
        }
        else if(c_name=='task'){
            arr[i]=x;
            ar[i]=y;
        }
    }
  }
}

and i get the same results with my first script

Answer 1

instead of using ar[i] in the loop, use ar[j] like this:

j=0;
for(i=0;...) {
   if(...) {
      ar[j]=...;
      j = j + 1;
   }
}

do you see the mistake in your code?
