Checks if `sessionStorage` is enabled.
|
|
|
|
- Use a `try...catch` block to return `true` if all operations complete successfully, `false` otherwise.
|
|
- Use `Storage.setItem()` and `Storage.removeItem()` to test storing and deleting a value in `Window.sessionStorage`.
|
|
|
|
```js
|
|
const isSessionStorageEnabled = () => {
|
|
try {
|
|
const key = `__storage__test`;
|
|
window.sessionStorage.setItem(key, null);
|
|
window.sessionStorage.removeItem(key);
|
|
return true;
|
|
} catch (e) {
|
|
return false;
|
|
}
|
|
};
|
|
```
|
|
|
|
```js
|
|
isSessionStorageEnabled(); // true, if sessionStorage is accessible
|
|
```
