Data exists in table? Checkbox Problem

Question:
How can I check if a box was clicked last time(value saved in the table)

Look at the appropriate field in the database. If you use form_for, it
does that for free.

into the blue:
if "value" exists in "table"
document.getElementById("checkbox1").checked = true
if "value" doesn't exist in "table"
document.getElementById("checkbox1").checked = false

Why on earth would you do this in client-side JavaScript instead of on
the server side? That doesn't appear to make sense.

Thx for your answers

Best,

And what did you try?

... but everything in my checkbox is deleted
after refreshing the page (instead of the values in my database) so how
can I ask for them.

The behavior of unsubmitted forms in the browser on page refresh is
somewhat browser-dependent, but most browsers will reset them. This is
what users expect.

Why do you need this functionality, anyway? If you explain what you're
trying to achieve by doing this, perhaps we can be of more help.

Thx till now...

Best,
