===== Chapter 6: JS Variables =====

[[http://niche-canada.org/member-projects/zotero-guide/chapter6.html|HWZT 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 [[http://niche-canada.org/member-projects/zotero-guide/sample1.html|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=<code>http://niche-canada.org/member-projects/zotero-guide/</code>
  - 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 <code>Click on the "Detect Code" tab</code>, click on tab=Code. As directed, in that tab enter the expressions <code>var myVariable=4;
Zotero.debug(myVariable);
</code> 
  - Click on icon="Run doWeb" (a stylized thunderbolt) to obtain an evaluation like <code>12:00:00 ===>4<===(number)</code>
  - To also obtain an evaluation like <code>12:00:00 detectWeb returned type "undefined"</code>, you will need to also click on icon="Run detectWeb" (the eye next to the thunderbolt).

The subsequent examples behave similarly.
