    <p><strong>The Question: How do you determine a variable length string inbetween two similar characters?</strong></p> <p>Allow me to clarify:</p> <p>take the two URLs:</p> <p><strong>/designs/2012/mobile/v4/~html/ecom/</strong></p> <p><strong>/designs/2012/mobile/v4/~html/legal/</strong></p> <p>I'm trying to build an anchor with an ID that equals the name of each line's current directory: ecom, legal, local, etc. </p> <p>So the above directories would result in a page with the following:</p> <pre><code>&lt;a href="/designs/2012/mobile/v4/~html/ecom/" id="ecom"&gt;/designs/2012/mobile/v4/~html/ecom/&lt;/a&gt; &lt;a href="/designs/2012/mobile/v4/~html/legal/" id="legal"&gt;/designs/2012/mobile/v4/~html/legal/&lt;/a&gt; </code></pre> <p>I've been playing around with .lastIndexOf but am having little luck. I figured if I could say (warning psuedo-code ahead!) "get the 2nd to last / and pull the string inbetween that and the last /" but I'm not quite sure how to do that.</p> <p>Any tips or pointers?</p> <p>Here's my code thus far:</p> <pre><code>$(document).ready(function() { $.ajax({ url: "./~html", success: function(data){ $(data).find("a").each(function(){ var path = $(this).attr("href"); var fileNameIndex = path.lastIndexOf("/") + 1; var dirNameIndex = path.lastIndexOf("/"); var dirNameLength = path.length -1; var file = path.substr(fileNameIndex); var directory = path.substr(dirNameIndex); console.log("length of string: " + dirNameLength); console.log("Directory Index: " + dirNameIndex); console.log(directory); var idIndex = 1; if (file != "") { $('&lt;li&gt;&lt;/li&gt;').html('&lt;a href=\"' + path + '\"&gt;' + file + '&lt;/a&gt;').appendTo('#files'); } else { $('&lt;li&gt;&lt;/li&gt;').html('&lt;a href=\"' + path + '\"' + 'id=\"' + directory + '\"&gt;' + path + '&lt;/a&gt;').appendTo('#directories'); } }); } }); </code></pre> <p>});</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.
