function Cookiestorage (maxage, path) {var cookie = (function () {var cookie = {};
var all = Document.cookie; Get information on all cookies
Returns an empty object if it is an empty string
if (all = = = "")
return cookie;
Separating famous/value pairs
var list =all.split (";");
Iterate through each cookie
for (var i = 0; i < list.length; i++) {
var cookie = list[i];
Console.log (cookie);
var p = cookie.indexof ("="); Find the first "=" symbol
var name = cookie.substring (0, p); Get the name of the cookie
var value = cookie.substring (p + 1); Get the value of the cookie
Value = decodeuricomponent (value); To store a name value pair in an object
if (name = = = "UserId") {
Continue
}
Cookie[name] = value;
}
return cookie;
}());
Store the names of all cookies in an array
var keys = [];
for (var key in cookie) Keys.push (key);

Defining properties and methods for storage API public
The number of cookies stored
This.length = Keys.length;
Console.log (this.length);

Returns the name of the nth cookie and returns NULL if n is out of bounds
This.key = function (n) {
if (N < 0 | | n > Keys.length) {
return null
}
return keys[n];
};

Returns the cookie value for the specified name, or null if it does not exist

This.getitem = function (name) {
return Cookie[name] | | Null
};

Store cookie Values
This.setitem = function (key, value) {
if (! (Key in Cookie)) {
Keys.push (key);
this.length++;
}
Store the name/value pair data in a cookie object
Cookie[key] = value;
Start the formal setting of cookies
First encode the value of the cookie to be stored colleague creates a string in the form of a "First name = encoded value"
var cookie = key + "=" +encodeuricomponent (value);
Add the attributes of a cookie to the string
if (maxage) cookie + = "; Max-age= "+ maxage;
if (path) cookie + = "; Path= "+ path;

Setting cookies with the Document.cookie property
Document.cookie = cookie;
};

Delete the specified cookie
This.removeitem = function (key) {
if (! (Key in Cookie)) {
Return
}
Delete a specified cookie from an internally maintained cookie group
Delete Cookie[key];

Also delete the name of the cookie in the internal array
for (var i=0; i < keys.length; i++) {
if (keys[i] = = = key) {
Keys.splice (i, 1);
Break
}
}
This.length--;
Delete the specified cookie by setting the cookie value to an empty string and setting the validity period to zero
Document.cookie = key + "=; Max-age=0 ";
};

Delete all Cookies
This.clear = function () {
Loop all the coolie names and delete the cookies
for (var i = 0; i < keys.length; i++)
Document.cookie = Keys[i] + "=; Max-age=0 ";
Reset all internal states
cookie = {};
key = [];
this.length = 0;

};
}
