CF7 Add a read only attribute to an input field

Question

I have a function that validates an input field if a checkbox is checked:

jQuery("input[type='checkbox'][value='Internet Search']").click(function(){
    if (jQuery("input[type='checkbox'][value='Internet Search']").prop('checked'))
    {
        validatetext("input[name='internetSearch']", 4, 12, "input[type='checkbox'][value='Internet Search']");
    } else {
    errors[12] = true;
        checkInput("input[name='internetSearch']",errors[12]);
    }
});

What I'd like to do is add a read only attribute to the if/else statement. How would this be written?

Answer 1

It`s not completely clear to me how your fields are organized but adding the following piece of code to your if statements should help making the desired input "readonly":

jQuery('input[name="internetSearch"]').prop('readonly', true);
