Source: https://github.com/windingwind/zotero-actions-tags/blob/master/README.md

Illustrates the use of the `require` function in JavaScript to import global variables and modules within the Zotero Actions Tags custom script environment. Examples include accessing ZoteroPane functions and retrieving item details from the current tab.

```javascript
const selectedItems = require('ZoteroPane').getSelectedItems()
```

```javascript
const Zotero = require("Zotero");
const Zotero_Tab = require("Zotero_Tab");
const itemID = Zotero_Tabs._tabs[Zotero_Tabs.selectedIndex].data.itemID;
const item = Zotero.Items.get(itemID);
```

### Handling Multiple Items in JavaScript

Source: https://github.com/windingwind/zotero-actions-tags/blob/master/README.md

Provides JavaScript examples for handling scenarios where multiple Zotero items are selected. It shows how to differentiate between single-item triggers and multi-item triggers to avoid duplicate operations and process all selected items.

```javascript
if (item) {
  // Disable the action if it's triggered for a single item to avoid duplicate operations
  return;
}

if (items?.length > 0) {
  // Do something with all selected items
}
```
