jQuery - if the checkbox is checked, stop unchecked

I am solving following situation - I have in table in database data and where by these data I have in HTML page checked or unche开发者_Python百科cked checkboxes.

I am wonder about the procedure, how to do, if I have checked checkbox, so how to disable to user unchecked this checkbox..

Exist some way, how to do?

Thanks a lot, M.

Just use HTML:

<input type="checkbox" checked disabled>

Note that the readonly attribute in HTML cannot be used with checkbox inputs.

After check on checkbox app attr disabled on checkbox.

.attr('disabled', true);

If you mean you want checkboxes that are checked to be disabled, you can use the disabled attribute:

<input type="checkbox" disabled="disabled" />

If you want to disable a checkbox when it is clicked, with jQuery, you can do this:

$("input[type=checkbox]").click(function() {
      $(this).attr("disabled", true);
});

$(checkbox).attr('readonly', true); Where "checkbox" is appropriate jQuery selector, don't use this code literally
