Question

I have a form with lets say 50 checkboxes. And i want to disable them on form load, i do it like this:

$(document).ready(function() {
   $("#check").attr("disabled", "disabled");
});

but this only disables the first checkbox. All checkboxes got the id='check'.

Your checkboxes need to have unique ID, ID = unique identifier.
Instead use classes:

add class check to each checkbox:

$(document).ready(function() {
   $(".check").attr("disabled", true);
});
