Only 1 checkbox can be checked

John Vo1 · ‎08-05-2020

I have this client script that should only allow 1 checkbox to be selected, but when I test it still lets me select I agree or I disagree. Can someone help me out?

Another thought is to possibly just ask if they Agree and then have a Yes/No drop down or if it is important that they choose agree or disagree use a multi-Choice box. Both these options could be made mandatory unlike check boxes and they can only chose one. Example of a multi-choice field.

You could also use a select box with options I Agree or I Disagree.

Hope you had replaced

v_prod & v_replace

with

i_agree & i_disagree

Yes I did.

To meet both your requirements of making at least one checkbox check and not both being checked.

function onSubmit() {
    //Type appropriate comment here, and begin script below
    if (g_form.getValue('i_agree') == 'true' && g_form.getValue('i_disagree') == 'true') {
        alert('You can only select one option');
        return false;
    } else if (g_form.getValue('i_agree') == 'false' || g_form.getValue('i_disagree') == 'false') {
        alert('you must select an option');
        return false;
    }

}

Brian,

I get this error message even with 1 selected.

Looks like you have 4 check boxes. What are the variable name for each checkbox? It almost seems like both I Agree and I Disagree have the same variable name which should not be possible.
