Zotero清除extra栏信息

Zotero在新增文章时，extra栏会自动附带信息，这使得更新引用量时，有所干扰，所以有必要清除extra信息，再更新引用次数。

具体操作 Tools -> Developer -> Run JavaScript

粘贴以下代码，并运行：

var fieldName = "extra";
var newValue = "";

var fieldID = Zotero.ItemFields.getID(fieldName);
var s = new Zotero.Search();
s.libraryID = ZoteroPane.getSelectedLibraryID();
var ids = await s.search();
if (!ids.length) {
return "No items found";
}
await Zotero.DB.executeTransaction(async function () {
for (let id of ids) {
let item = await Zotero.Items.getAsync(id);
let mappedFieldID = Zotero.ItemFields.getFieldIDFromTypeAndBase(item.itemTypeID, fieldName);
item.setField(mappedFieldID ? mappedFieldID : fieldID, newValue);
await item.save();
}
});
return ids.length + " item(s) updated";
