    <p>Long time user, first time asker; very new to regular expressions. I'm a designer trying to make my life in InDesign easier, so please be patient if this is an easy one :)</p> <p>I'm working on a script that pulls pages out of a master file into a template file. Some of these master pages have layers that are to be used when the final file is exported to PDF for print; other layers are to be used when the final file is exported to e-mailing. So, if someone checks an option to save for e-mailing, I want the print layers to hide and the e-mail layers to show. Easy enough, but I wanted to streamline the code as a function so I could specify "print" or "email" as a variable, and then the script would match that to any variable that has "print" in it. Regex territory.</p> <pre><code>var openDocument = app.documents.item(0); var LayerLength = openDocument.layers.length; wordToMatch = "print"; for (i=0;i&lt;LayerLength;i++) { myRegEx = new RegExp(wordToMatch,"i"); str = openDocument.layers.item(i).name; if (str.search(myRegEx) &gt;= 0) { openDocument.layers.item(i).visible = true; } } </code></pre> <p>So, this actually works. It does what I want it to do (Haven't put it in a function yet but I'll get there). It finds layers with "print" in them and then makes them visible.</p> <p>This didn't seem ideal to me, though. I thought it would make more sense to define the regex once and then use it multiple times in the for loop, as follows:</p> <pre><code>wordToMatch = "print"; myRegEx = new RegExp(wordToMatch,"i"); for (i=0;i&lt;LayerLength;i++) { str = openDocument.layers.item(i).name; if (str.search(myRegEx) &gt;= 0) { openDocument.layers.item(i).visible = true; } } </code></pre> <p>But this only does what it's supposed to do on the first layer, then it's unable to match any subsequent layers.</p> <p>Why is this? I feel like I'm misunderstanding something fundamental here, and I'd like to know what that is. </p> <p>Thanks, Brendan</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
