Uncaught ReferenceError: Loading is not defined

Solved -> '#loadingIcon' is missing

  <div id="loadingIcon" style="display:none" class="lds-ripple"><div></div><div></div></div>

function Loading(obj) {

    $.blockUI({ message: $('#loadingIcon'), css: { "background-color": "transparent", border: 0 } });

    if (obj != null)

        obj.hide();

}

function Loaded(obj) {

    $.unblockUI();

    if (obj != null)

        obj.fadeIn(150);

}
