How to save session only cookies with JavaScript?

To save session only cookies with JavaScript, we can use session storage instead of cookies.

For instance, we write

const myVariable = { a: [1, 2, 3, 4], b: "some text" };

sessionStorage["myVariable"] = JSON.stringify(myVariable);
const readValue = JSON.parse(sessionStorage["myVariable"]);

to save an entry with key myVariable into session storage with

sessionStorage["myVariable"] = JSON.stringify(myVariable);

Since myVariable is an object, we’ve convert it to a string with JSON.stringify before we can save the value.

Then we read the value by the key with

sessionStorage["myVariable"]

Then we call JSON.parse to parse the stringified JSON object into a JavaScript object.

Conclusion

To save session only cookies with JavaScript, we can use session storage instead of cookies.
