复制代码 代码如下: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 ) ); } // ---------------------------------------------------- // 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' : '' ); } // ---------------------------------------------------- // 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'; }
