<p>I am trying to generate some Javascript for a Comet callback. The code that I have works, but needs to use several additional variables that should not really be required. The problem is that I am not sure how to access an element in an array that is returned from a <a href="http://scala-tools.org/mvnsites/liftweb-2.2/framework/scaladocs/net/liftweb/http/js/JE/Call.html" rel="nofollow">Call</a>.</p> <pre><code>JsCrVar("node" + c.id, Call("dataTable.fnAddData", JsArray(Text(c.name), Text(c.initials), makeDeleteButton(c)), Num(0))) & JsCrVar("row" + c.id, Call("dataTable.fnGetNodes", JsVar("node" + c.id + "[0]"))) & SetExp(JsVar("row" + c.id + ".id"), Str(c.id.toString)) </code></pre> <p>This generates JavaScript like follows (indented for readability):</p> <pre><code>var node2 = dataTable.fnAddData(["Test User", "TU", "<button onclick=\"liftAjax.lift_ajaxHandler(&quot;F306228675550KFT=true&quot;, null, null, null); return false;\">delete</button>"] ,0); var row2 = dataTable.fnGetNodes(node2[0]); row2.id = "2"; </code></pre> <p>The code that I would like to generate is as follows:</p> <pre><code>dataTable.fnGetNodes(dataTable.fnAddData(["Test User", "TU", "<button onclick=\"liftAjax.lift_ajaxHandler(&quot;F306228675550KFT=true&quot;, null, null, null); return false;\">delete</button>"] ,0)[0]).id = "2"; </code></pre> <p>How does one</p> <ol> <li>Get the <code>0</code>th element from the returned array?</li> <li>Get the sub-element 'id' from that returned object?</li> </ol>

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.
