onsubmit glide ajax issue

[prafful garg]

Can someone help me understand why this code is not working? I'm trying to use GlideAjax in an onSubmit client script

This is not a real requirement—I just want to learn because I was asked this in an interview last time.

Also, if this question comes up in an interview, what would be the best way to answer it?

function onSubmit() {
    //Type appropriate comment here, and begin script below
    var a = new GlideAjax('S_i_catalog_item');
    a.addParam('sysparm_name', 'get_email');
    a.addParam('sysparm_name_field', g_form.getValue('user'));
    a.getXML(callback);

    function callback(response) {
        var answer = response.responseXML.documentElement.getAttribute('answer');
        g_form.setValue('onsubmit_email_user', answer);
        g_form.submit();

    }
    return false;

}

@prafful garg - Glide Ajax will fail as it's asynchronous. Try to use onChange instead of onSubmit.
