Validation on form field (radio button)

(0) ShareShare
ReportReport
Posted on by

Hey,

 

I want to get a validation on a form field typ radio button. It is about the Terms of use (schema name: termsofuse).

 

I want that the form can only be submitted if the radio button is checked with yes (value: 1).

 

Could anyone assist my with this? I know there is a javascript validation for it, yet i am not sure how to implement it correctly/modify it.

 

Thanks!

    Hi! Quick update! I did sove it. Did not use the right id´s


    $(document).ready(function() {
        
        removeValidator("termsofuse_1");
        $("#termsofuse_1").parent().prev().removeClass('required');

        // Add event validator
        if (typeof(Page_Validators) == 'undefined') return;

            // Create new validator
            var newValidator = document.createElement('span');
            newValidator.style.display = "none";
            newValidator.id = "termsofuseValidator";
            newValidator.controltovalidate = "termsofuse_1";
            newValidator.errormessage = "<a href='#termsofuse_label'>Bitte akzeptieren Sie die Nutzungsbediengungen.</a>";
            newValidator.evaluationfunction = function() {

            if($("#termsofuse_1").is(':checked'))
            {
                return true;
            }
            else

        Page_Validators.push(newValidator);
    })

    function removeValidator(fieldName) {
    var count = 0;
    for(var i =0; i < Page_Validators.length - count; i++){
    if (Page_Validators[i - count].id == "RequiredFieldValidator" + fieldName) {
    Page_Validators.splice(i - count, 1);
    count++;
    }
    }
    $("#" + fieldName + "_label").parent().removeClass("required");
    }

    Hi @OliverRodrigues 

     

    Hey that would be my code:

     

    if (window.jQuery) {
    (function ($) {
    $(document).ready(function () {
    if (typeof (Page_Validators) == 'undefined') return;
    // Create new validator
    var newValidator = document.createElement('span');
    newValidator.style.display = "none";
    newValidator.id = "termsofuseValidator";
    newValidator.controltovalidate = "termsofuse";
    newValidator.errormessage = "<a href='#termsofuse_label'>Terms of use needs to be selected with "Yes" </a>";
    newValidator.validationGroup = ""; // Set this if you have set ValidationGroup on the form
    newValidator.initialvalue = "";
    newValidator.evaluationfunction = function () {
    var termsofuse= $("#termsofuse").val();
    if (termsofuse != 1) return true; // check if terms of use radio button is selected with No (value 0).

    return false;
    } else {
    return true;
    }
    };
    //Not sure what this is for
    // Add the new validator to the page validators array:
    Page_Validators.push(newValidator);
    -
    // Wire-up the click event handler of the validation summary link
    $("a[href='#emailaddress1_label']").on("click", function () { scrollToAndFocus('emailaddress1_label','emailaddress1'); });
    });
    }(window.jQuery));

     

    Basically I need that the form is only sendable if:

    Yet I am not sure how to write or modify the javascript validation properly to achieve this

    @ragavanrajan Hey but then I could submit the form if the radio button value "no" is selected or? and that the form only gets submitted when selecting yes

    Hi @Anonymous 

    Try making it as required field. This will throw a validation error to user when they try to submit it. 

     

    Hope it helps.
