Hello, I wonder if it is possible to store files in sessionStorage and how I can do it. I tried with JSON.stringfy() and JSON.parse() methods and no success as follows
var elemento = document.getElementById('inputComArquivo');
sessionStorage.setItem('arquivos', JSON.stringfy(elemento.files));
I think the API of
storagehas a memory limit, and storing large files is not a good idea. Files will be large?– Luiz Felipe
Searching around, apparently the limit is 5MB. And has this site to test in practice :) . And I can’t imagine a case that makes sense, you really need to save the contents of a file there? Maybe your problem is different and you’re trying to solve it in a bad way

Hello, thanks for the return, thanks! Well, in this case is a registration page with a field where I can attach up to 3 files (.pdf, xlsx, etc...). If I for example click on "register" and there is some error in the registration as an empty field, the page simply reloads me alerting me which fields I have not filled in and this is how I lose the files I previously attached and have to attach again in the register (typical of Django) My terefa is precisely to keep the files I entered if the page reloads due to error in the registration. That’s all it’s for.
