I can't get query string from url at LIFF

[skypu3]

I used the let urlParams = new URLSearchParams(window.location.search);
to get parameter from LIFF.
However, it is undefined, do you know how to get query string from LIFF ?

Hi @skypu3, thank you for your question, and I apologize for the lack of response.
You should be able to get the query string parameters using URLSearchParams.
For example (using your syntax),

let urlParams = new URLSearchParams(window.location.search);
console.log(urlParams.get('{some_parameter}'));

should print the query parameter you want.

I hope this helps!
