    <p>I've been working on a project that some other developers had started and I'm trying to understand the code while also completing the project. Currently what I have is some json with links and a url text (pretty much a quick description), what I need to do is on a button click I want to display each of the links with their correct text and make it a clickable link. The way this needs to be done is using nodes which I'm not 100% knowledgeable on. If I need to explain this more please let me know also I have provided an example of what I'm currently working with. Thanks</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html lang="en"&gt; &lt;head&gt; &lt;meta charset="utf-8" /&gt; &lt;title&gt;JavaScript And JSON&lt;/title&gt; &lt;/head&gt; &lt;body bgcolor='#CED3F3'&gt; &lt;button onclick="appendUrl()"&gt;Append&lt;/button&gt;&lt;br&gt; &lt;br&gt;&lt;script id = "i"&gt; function category() //adding function with button click removes html page styling? { var category = { "content": [ { "links": "basic information", "urlText": "Basis Information System", "urlDesc": "portal for technology development, people search, a keyword search ." }, { "links": "http://site.com", "urlText": "Net", "urlDesc": "the entry page example" }, { "links": "http://newsgroups.com", "urlText": "Newsgroups", "urlDesc": "information internal newsgroups, usage, tools, statistics, netiquette" }, { "links": "http://site2.com", "urlText": "Another site", "urlDesc": "community for transfer of knowledge and technical information" }, { "links": "http://news.com", "urlText": " some news", "urlDesc": "place with news" } ] } &lt;/script&gt; &lt;script&gt; function appendUrl() { //there needs to be a loop here? var link = "needs to loop through links?" var node=document.createElement("LI"); var nodeA=document.createElement("A"); var textnode=document.createTextNode(); node.appendChild(nodeA); nodeA.appendChild(textnode); nodeA.href=(link); nodeA.target="_blank"; document.getElementById("i").appendChild(node); } &lt;/script&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

    1. COCould you be more specific about what you don't understand? That being said, a few comments about your current code: (1) function `category` does nothing, it should at least return your data; (2) on the other function, yes, you should be looping your data object; and (3), don't append html into a `<script>` element, append to a ul where list items are valid children.

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.
