SimpleStorage

SimpleStorage is an object storage. Just like the Map object in JavaScript, it collects the key-value pairs, where the keys can be of any type.

Use the methods of this class, for example, to manage the data that can be useful for client-side scripts of the widgets or forms in the future. See the code example below:

Example:

if (SimpleStorage.hasItem('portalLogo')) {
  s_widget.setFieldValue("HasLogo", true);
  s_widget.setFieldValue("logo", SimpleStorage.getItem("portalLogo"));
} else {
  await s_widget.serverUpdate();
  SimpleStorage.setItem('portalLogo', s_widget.getFieldValue("logo"));
}
