Session 存储未给出实际值

Question

I'm trying to console.log a value taken from an input from session storage but it gives me " [object HTMLInputElement " but not the actual value of the input what can be done? Here's my code

let us = document.getElementById('us')
sessionStorage.setItem("user",us)
setTimeout(function() {
let h = sessionStorage.getItem("user")
console.log(h)
}, 200);

Answer 1

Your script is working correctly but document.getElementById('us') is html element, you store HTML element. I think you need value or something, you write or change like this document.getElementById('us').value or what you need to do.

Answer 2

As @Huseyint said, you must use <HTMLInputElement>.value to get the value of the input field. More info here . For example, your code would be rewritten like this:

const us = document.getElementById('us');
sessionStorage.setItem('user', us.value);
const h = sessionStorage.getItem('user');
console.log(h);

Or if you want to save all of the properties you could do something like this:

const us = document.getElementById('us');
sessionStorage.setItem('user', us);
const h = sessionStorage.getItem('user').value;
console.log(h);

Either one should work. Also, note that setItem() isn't a promise so you don't need the setTimeout .

Hoped this helped!
