    <p>I'm having trouble in parsing my JSON data in jQuery autocomplete. My JSON comes from this code:</p> <pre><code>&lt;cfset theQ = lcase(q)&gt; &lt;cfquery datasource="#source#" name="qry" maxrows="20"&gt; select top 10 lastname from info where lower(lastname) like '#theQ#%' order by lastname &lt;/cfquery&gt; &lt;!--- Before we can serialize the query, we need to convert it to an array of structs. ---&gt; &lt;cfset rows = [] /&gt; &lt;!--- Loop over the query to convert it. ---&gt; &lt;cfloop query="qry"&gt; &lt;!--- Create a row struct. ---&gt; &lt;cfset row = {} /&gt; &lt;!--- Add each column to our struct. ---&gt; &lt;cfloop index="column" list="#qry.columnList#" delimiters=","&gt; &lt;cfset row[ column ] = qry[ column ][ qry.currentRow ] /&gt; &lt;/cfloop&gt; &lt;!--- Append the row struct to the row array. ---&gt; &lt;cfset arrayAppend( rows, row ) /&gt; &lt;/cfloop&gt; &lt;!--- Now that we have converted our query to an array of structs, we can serialize it using the serializeJSON() method. ---&gt; &lt;cfset serializedQuery = serializeJSON( rows ) /&gt; &lt;cfoutput&gt;#serializedQuery#&lt;/cfoutput&gt; </code></pre> <p>I converted my query into array of structures and then serialized it to JSON. Now, parsing this JSON in jQuery autocomplete does not work. The data I get looks like this:</p> <pre><code>[{"lastname":"abc"},{"lastname":"def"},{"lastname":"ghi"}] </code></pre> <p>Here is the code for autocomplete:</p> <pre><code>$(document).ready(function() { $("#name").autocomplete("data/name.cfm",{ minChars:1, delay:10, autoFill:false, matchSubset:false, matchContains:1, cacheLength:10, selectOnly:1, dataType: 'json', parse: function(data) { var parsed = []; var dataParsed = $.parseJSON(data); for (var i = 0; i &lt; dataParsed.length; i++) { parsed[parsed.length] = { data: dataParsed[i], value: dataParsed[i].lastname, result: dataParsed[i].lastname }; } return parsed; }, formatItem: function(item) { return item; } }); </code></pre> <p>When I type in the text field, I get the whole JSON string as the search result. I've looked into other codes for parsing but still I can't get it working. Any help? Thanks.</p> <p>References: Simon Whatley for autocomplete; Ben Nadel for query to array of structs and serialize to json</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
