How do I add scripts?

I tried to delete all the blocks but in the preview the page remains as before.

The text editor block does not exist, but the text is there.

Hi,

Let me see if I understood you correctly. You do not see the changes in the editor but only on the live site?

I’m trying to insert the code of this program; https://github.com/ethanaobrien/emulatorjs.

I put the Divs on Elementor and today I installed the Insert Headers and Footers plugin.

After that I put the Nintendo Gameboy Advance script in the Footer. I only see the game container, but it doesn’t launch.

<script type="text/javascript">
    EJS_player = '#game';
    EJS_biosUrl = 'public_html/Bios/Nintendo/GameboyAdvance/gba_bios907607290.bin';
    EJS_gameUrl = 'public_html/Games/Nintendo/GameboyAdvance/dragonball-z-buu-s-fury-usa.zip'; // Url to Game rom
    EJS_core = 'gba';
    EJS_pathtodata = 'public_html/emulatorjs-main/data/'; //path to all of the wasm and js files. MUST all be in the same directory!!
</script>
<script src="data/loader.js"></script>

Elementor’s problems were 2;
– The text editor block disappeared, but the text was there. I couldn’t make changes.
– The HTML block only saved the DIV, while the script was cleared.

I don’t know what I’m doing wrong and what I should do.

Hi,
Are you still needing assistance?

No.
