dev:how_to_write_a_zotero_translator_2nd_edition:chapter_6 [Zotero Documentation]

This is an old revision of the document!

We’re in the process of updating the documentation for Zotero 5.0. Some documentation may be outdated in the meantime. Thanks for your understanding.

Chapter 6: JS Variables

A few things have changed since How To Write a Zotero Translator was written. To use its first Scaffold example as an example:

Ensure the first sample page is open in your browser and has focus.
Open Scaffold 2.0 from the Firefox main menu with Tools>Scaffold. This should popup dialog=“Zotero Scaffold”.
If you are not already in tab=Metadata, select that. Enter some text in the Label and Creator fields.
The URI of the sample page has changed since HWZT, so you will need to enter Target=
```
http://niche-canada.org/member-projects/zotero-guide/
```
Hit button=“Test Regex”. You should get a result, in the “Test Frame” on the right of the tab, similar to that described in HWZT.
Instead of
```
Click on the "Detect Code" tab
```
, click on tab=Code. As directed, in that tab enter the expressions
```
var myVariable=4;
Zotero.debug(myVariable);
```
Click on icon=“Run doWeb” (a stylized thunderbolt) to obtain an evaluation like
```
12:00:00 ===>4<===(number)
```
To also obtain an evaluation like
```
12:00:00 detectWeb returned type "undefined"
```
, you will need to also click on icon=“Run detectWeb” (the eye next to the thunderbolt).

The subsequent examples behave similarly.
