DOMDocument and insertbefore?

Question

JavaScript

Hello,
there is markup -

<p> ... </p>
<p><img src=""></p>

You need to take a picture and stick it in front of the paragraph in which it was originally. Need to make it happen

<p> ... </p>
<img src="">

I try $image->parentNode->insertBefore($image);- it turns out garbage.
What am I doing wrong? Thank you.

Answer 1

The correctness should be checked by the server when you want something from it with this token. On the client, everything is simple - there is a token, we consider that the user is logged in, draw buttons for him and go to the server with this token - if something is wrong, the server will tell us, for example, it will return 401, in this case we delete the token on the client and send the user to /login.

I have done this:
In the store I store the key verification function, which checks if there is a key (jwt), then check it for obsolescence, if the time has come, send a request to renew the key, if not, return true, if there is no key, return false .
Further, I slip this check under each route in the global router.beforeEach, if the check returns true, next() follows from the route, if false, redirect to the page with the login form
