Available Methods Are given Below:

• addObjectToCookie(key, object);
• deleteObjectFromCookie(key);
• updateObjectOfCookie(key, newObject);
• resetCookie();

To read the all the cookie data call 'cookieMap' and for deep data reading use Javascript Map default functions. for example:

• cookieMap.get(key) – returns the value by the key, undefined if key doesn’t exist in map.
• cookieMap.has(key) – returns true if the key exists, false otherwise.
• cookieMap.size – returns the current element count.
• other reading strategy is give below part of the code as example.

You can use this in any web project. Just add the script link to your project.

Here is some Practice Example

add

while reading always use key in String format.
while adding object key is always converted to string internally.

resetCookie();
var person1 ={"firstName":"A", "lastName":"AA", "age":10};
var person2 ={"firstName":"B", "lastName":"BB", "age":20};
var person3 ={"firstName":"C", "lastName":"CC", "age":30};
var person4 ={"firstName":"D", "lastName":"DD", "age":40};
addObjectToCookie(1, person1);
addObjectToCookie("2", person2);
addObjectToCookie(33, person3);
addObjectToCookie('player', person4);
console. log("After adding object : ");
console. log(cookieMap);

read

while reading always use key in String format.
while adding object key is always converted to string internally.

console.log('Get Object specific value against a key : firstName is ' + cookieMap.get("33").firstName);

console.log("reading all keys and Objects in array format");
for (var person of cookieMap.entries()) {
    console.log(person);
}

console.log("reading all keys");
for (var person of cookieMap.entries()) {
    console.log(person[0]);
}

console.log("reading all objects");
for (var person of cookieMap.entries()) {
    console.log(person[1]);
}

console.log("reading all objects instances ");
for (var person of cookieMap.entries()) {
    console.log("retrieving age from objects  " + person[1].age);
}

update

while reading always use key in String format.
while updating object key is always converted to string internally.

resetCookie();
var person1 ={"firstName":"A", "lastName":"AA", "age":10};
addObjectToCookie("2", person1);
var person3 ={"firstName":"B", "lastName":"GGG", "age":60};
updateObjectOfCookie("2", person3);
console.log("After updating object : ");
console.log(cookieMap);

Delete

while deleting always use key in String format.
while deleting object key is always converted to string internally.

resetCookie();
var person1 ={"firstName":"A", "lastName":"AA", "age":10};
addObjectToCookie("2", person1);
deleteObjectFromCookie("2");
console.log("After deleting object : ");
console.log(cookieMap);

reset

resetCookie();
