Onsubmit script is not working with script

[is_12]

Hello Community !

function onSubmit() {

    if (g_user.hasRole('sn_customerservice_agent')) {

        var ga = new GlideAjax('catalogUtils');

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

        ga.addParam('sysparm_account', g_form.getValue('account'));

        ga.addParam('sysparm_userId', g_form.getValue('contact_name'));

        ga.addParam('sysparm_catalogItem', g_form.getUniqueValue());

        ga.getXMLAnswer(setData);

    }

    function setData(response) {

        var answer = response;

        alert('reponse' + answer);

        if (answer == 'false') {

            alert(getMessage('You are not allowed to order as there is an existing request for this customer'));

           return false;

        } else {

            alert("else if alert");

            return true;

        }

    }

}

I'm getting the alert message but form is getting submitted.

Tried with getXMLWait(), it is getting supported

Thanks,

@OlaN @Ankur Bawiskar after the alert message, agent should not be able to submit the form, if he click's as well it should be restricted.

Sorry but you can't disable the Order Now button without DOM manipulation which is not recommended practice.

I hope your Architect or Tech Lead or the person who has assigned this story knows this very well what's best practice and as a Lead their job is to Consult and provide the best solution.

If my response helped please mark it correct and close the thread so that it benefits future readers.
