Set/Get/Delete Cookies with jQuery


There are a lot of plugins you can use to set, get, and delete cookies using jQuery, but there’s also a fairly simple code that will achieve all three of those actions without the need for a heavy plugin. Check out the snippets below:

Set cookies:

function setCookie( name, value, expires, path, domain, secure ) {
 var today = new Date();
 today.setTime( today.getTime() );
 if ( expires ) {
 expires = expires * 1000 * 60 * 60 * 24;
 }
 var expires_date = new Date( today.getTime() + (expires) );
 document.cookie = name+'='+escape( value ) +
 ( ( expires ) ? ';expires='+expires_date.toGMTString() : '' ) + //expires.toGMTString()
 ( ( path ) ? ';path=' + path : '' ) +
 ( ( domain ) ? ';domain=' + domain : '' ) +
 ( ( secure ) ? ';secure' : '' );
}

Get cookies:

 function getCookie( name ) { 
 var start = document.cookie.indexOf( name + "=" );
 var len = start + name.length + 1;
 if ( ( !start ) && ( name != document.cookie.substring( 0, name.length ) ) ) {
 return null;
 }
 if ( start == -1 ) return null;
 var end = document.cookie.indexOf( ';', len );
 if ( end == -1 ) end = document.cookie.length;
 return unescape( document.cookie.substring( len, end ) );
}

Delete cookies:

function deleteCookie( name, path, domain ) {
 if ( getCookie( name ) ) document.cookie = name + '=' +
 ( ( path ) ? ';path=' + path : '') +
 ( ( domain ) ? ';domain=' + domain : '' ) +
 ';expires=Thu, 01-Jan-1970 00:00:01 GMT';
}
