Disabling Load Mask

To disable the load mask completely, set the syncMode property to ‘false’ as shown in the following sample JS code snippet:

var param = {
    "PAGE_CODE_TYPE" : 'ALERT_CODE',
    "INPUT_ACTION" : 'UPDATE_REFRESH_ACTION',
    "PRODUCT_NAME" : 'ALERTS',
    "INPUT_FUNCTION_CODE" : 'VSBLTY',
    "INPUT_SUB_PRODUCT" : 'ALERTS',
    "IS_FILTER_FORM" : false,
    "MSG_ID" : msgId
  };
  ct.Ajax({
    params : param,
    syncMode : false, // When syncMode is 'false', load mask is disabled.
    success : function(responseP, optionsP) {
      widObj.refreshWidgetData();
    }
  });

syncMode property is set to 'false' in above code snippet (line number 12).
