    <p>I want to populate a datalist based on JSON data to create an autocomplete field.</p> <p>I have managed to get the following to work thanks to a <a href="http://www.raymondcamden.com/index.cfm/2012/6/14/Example-of-a-dynamic-HTML5-datalist-control" rel="nofollow">this tuotorial</a>:</p> <p>This json data:</p> <pre><code>{"COLUMNS":["ARTNAME"],"DATA":[["Morning Forest"],["Morph"],["Mountains"],["Mom"]]} </code></pre> <p>I can parse fine using this code: $(document).ready(function() {</p> <pre><code>if(document.createElement("datalist").options) { $("#search").on("input", function(e) { var val = $(this).val(); if(val === "") return; //You could use this to limit results //if(val.length &lt; 3) return; console.log(val); $.get("artservice.cfc?method=getart&amp;returnformat=json", {term:val}, function(res) { var dataList = $("#searchresults"); dataList.empty(); if(res.DATA.length) { for(var i=0, len=res.DATA.length; i&lt;len; i++) { var opt = $("&lt;option&gt;&lt;/option&gt;").attr("value", res.DATA[i][0]); dataList.append(opt); } } },"json"); }); } }) </code></pre> <p> </p> <p>and the autocomplete works as per the example I linked to.</p> <p>I am trying to parse this as my datasource:</p> <pre><code>{"responseHeader":{"status":0,"QTime":1,"params":{"q":"*a*","wt":"json"}},"response":{"numFound":2,"start":0,"docs":[{"id":"13","body":"Hi guys\r\n\r\nCould you please help me.\r\n\r\nCheers,\r\n\r\nTest Three","title":["Patience"],"_version_":1427207573191262208},{"id":"45","body":"Has been implemented!","title":["Validation"],"_version_":1427207573192310784}]}} </code></pre> <p>I am trying to get the 'Body' to auto-complete in the datalist. I'm not sure how to get it to work with this more complex json data.</p>

    2. COiterate through `res.response.docs` using **for..in loop** and see `res.response.docs[i].body` where i is looping variable. I haven't tried that, But, I think it'll give the required result.

    3. COThanks, will look into it. Is it possible to get it working using code like that in the tutorial? It's working already with the simple json data. Is it possible to get it to work with the 'nested' json data?

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.
