OnSubmit Catalog client script not working

[Laxmi Sadhana K]

function onSubmit() {

    var user = g_form.getValue('requestbytmp2_name');

    var ga = new GlideAjax('CheckOAuthToken');

    ga.addParam('sysparm_name', 'isTokenValid');

    ga.addParam('sysparm_user_id', user);

    ga.getXML(GetData);

   function GetData(response) {

        var ans = response.responseXML.documentElement.getAttribute("answer");

            if (ans == 'true') {

            alert('You have a valid token.');

            g_form.submit();

            return true;

        } else if (ans == 'false') {

            alert('You do not have a valid token. Please login to a new session before proceeding.');

            return false; 

        } else {

            alert('Unexpected response: ' + ans);

            return false; 

        }

    }

}

I am using this script to prevent form submission when isTokenValid returns false, but it is allowing the form submission. I tried with XML wait but it is not working. Is there a better way to achieve it?

Hi @Laxmi Sadhana K ,

function onSubmit() {
    if (g_scratchpad.isFormValid) {
        return true;
    }
    var user = g_form.getValue('requestbytmp2_name');
    var ga = new GlideAjax('CheckOAuthToken');
    ga.addParam('sysparm_name', 'isTokenValid');
    ga.addParam('sysparm_user_id', user);
    ga.getXMLAnswer(function(ans) {
        if (ans == 'true' || ans == true) {
            alert('You have a valid token.');
            g_scratchpad.isFormValid = true;
            g_form.submit(actionName);
        } else if (ans == 'false') {
            alert('You do not have a valid token. Please login to a new session before proceeding.');
            return false;
        } else {
            alert('Unexpected response: ' + ans);
            return false;
        }
    });
    return false;
}
