JS Object-oriented programming for COOKIE_JS object-oriented

If you have a better opinion, you can discuss it!

Copy Code code as follows:

/*
* Js Class Cookie
* AUTHOR:MR Co
*/
var Cookie = function (/*cookie name */name) {
this. $name = name;
var allcookies = Document.cookie;
if (allcookies = = ") return;
var cookies = Allcookies.split (';');
var cookie = null;
for (var i = 0; i < cookies.length; i++) {
if (cookies[i].substring (0,name.length + 1) = = (name + ' = ')) {
cookie = cookies[i];
Break
}
}
if (cookie = null) return;
var cookieval = cookie.substring (name.length + 1);
var a = Cookieval.split (' & ');
for (var i = 0; i < a.length; i++) {
A[i] = a[i].split (': ');
}
for (var i = 0; i < a.length i + +) {
This[a[i][0]] = decodeURIComponent (a[i][1]);
}
}
/*
* Save Cookie Data Object
*/
Cookie.prototype.store = function (/* Expiration time (1 means one day, etc.) */daystolive,/* current cookie valid address */path,/* current cookie valid domain name Access */domain,/* Security */secure) {
var cookieval = ';
For (Var prop in this) {

if (Cookieval!= ') Cookieval + = ' & ';

}
var cookie = this. $name + ' = ' + cookieval;
if (daystolive | | daystolive = = 0) {

*/

Test JS DEMO

Copy Code code as follows:

function Testfn () {
var cookie = new Cookie (' Test ');
if (!cookie.name | |!cookie.color) {
Cookie.name = Prompt (' What is your name: ', ');
Cookie.color = Prompt (' What is your favorite color: ', ');
}
if (!cookie.visits) cookie.visits = 1;
else cookie.visits++;
Cookie.store (10);
Alert (' Color: ' + cookie.color + ' name: ' + cookie.name + ' visits: ' + cookie.visits);
}
