Make at least one checkbox required

[Vitalikssssss]

Hi there,

I have some check boxes, for example 5 and I want the form to not being submitted if at least one of them is checked.

 

How can I do that?

 

Thank you for looking into my question.

Hi @Vitalikssssss,

You may use the following code to prevent submittion if non of the checkboxes were not checked:
 

<script>

document.addEventListener("BeforeFormSubmit", myFunction);

function myFunction() {
    let FirstField = document.getElementById("InsertRecordnnn").checked;
    let SecondField = document.getElementById("InsertRecordname").checked;
    let ThirdField = document.getElementById("InsertRecordTF").checked;
    let FourthField = document.getElementById("InsertRecordnumber").checked;

    if (!FirstField && !SecondField && !ThirdField && !FourthField) {

        event.preventDefault();
        //for hiding the button container:
        //document.getElementsByClassName("cbSubmitButtonContainer")[0].style.display="none";
    }
};

</script>

The code should be added into the datapages' footer. Also you should rename the fields in the code to the ones you have on your form. Please see the screenshot for better understanding:
