Save/delete cookies on check/uncheck

@slaughtersOct 20.2009 — #Here are some functions I use to set and get Cookie values:

[CODE]//////////////////////////////////////////////////////////////////////////////
 // setCookie
 //
 //		Create a client side cookie. 

 //
 //  @param   c_name - Name to call the cookie 
 //  @param   value - Value to assign to the cookie
 //  @param   expiredays - *optional* number of days before cookie expires 

 //////////////////////////////////////////////////////////////////////////////
 function setCookie(c_name, value, expiredays) {
 var exdate = new Date();
 exdate.setDate(exdate.getDate() + expiredays);
 document.cookie = c_name + "=" + escape(value) + ((expiredays == null) ? "" : ";expires=" + exdate.toGMTString());
 }
 
 //////////////////////////////////////////////////////////////////////////////
 // getCookie
 //
 //		Get value of a client side cookie
 //
 //  @param   c_name - Cookie name. 

 //  @return  cookie value, or an empty string if cookie is not found
 //////////////////////////////////////////////////////////////////////////////
 function getCookie(c_name) {
 
  if (document.cookie.length > 0) {
   c_start = document.cookie.indexOf(c_name + "=");
   if (c_start != -1) {
   c_start = c_start + c_name.length + 1;
   c_end = document.cookie.indexOf(";", c_start);
   if (c_end == -1) c_end = document.cookie.length;
   return unescape(document.cookie.substring(c_start, c_end));
   }
  }
 
  return "";
 }[/CODE]

You would call the setCookie function with the "onclick" condition in the INPUT tag of your checkbox

@marcianoauthorOct 20.2009 — #Hello!

I have something like this function

'id' is the checkbox id.

For deletion, wouldn't be enough to set the same cookie expiration time to a date before than now?

function SDCookie(id, name, value, path, domain) {

if (id.checked == 1) {

var expires = -365 * 1000 * 60 * 60 * 24;

}

else {

var expires = 365 * 1000 * 60 * 60 * 24;

}

var today = new Date();

today.setTime( today.getTime() );

var expires_date = new Date( today.getTime() + (expires) );
 
  document.cookie = name + "=" +escape( value ) +
  ( ( expires ) ? ";expires=" + expires_date.toGMTString() : "" ) +
  ( ( path ) ? ";path=" + path : "" ) +
  ( ( domain ) ? ";domain=" + domain : "" );
 
  }

Check or uncheck the checkbox, the cookie is updated like check case.

My problem is here: if (id.checked == true)
