    <p>I am trying to create a Javascript file that I can reference from other domains that will allow the look and feel of a user's page to be changed.</p> <p>For example, The javascript file (www.mywebsite.com/123.js) would be referenced on www.userwebsite.com and could contain the below:</p> <pre><code>var thebody = document.getElementsByTagName('body')[0]; var newdiv = document.createElement('div'); var txtNode = document.createTextNode("Hello. This is a new node."); var divIdName = "mydiv"; var csslink = "http://www.anotherwebsite.com/style.css"; var newcss = document.createElement('link'); newcss.setAttribute('href',csslink); newcss.setAttribute('rel','stylesheet'); newcss.setAttribute('type','text/css'); newdiv.setAttribute('id',divIdName); newdiv.appendChild(txtNode); thebody.appendChild(newdiv); thebody.appendChild(newcss); </code></pre> <p>Which would insert a reference to a CSS file hosted on the user's website as well as add a new div to the DOM with the text node "Hello. This is a new node."</p> <p>I want the user to be able to login to a CMS (that I will build) so they can change the text that gets printed to the page without having to change the Javascript file that I give to them. The CMS would be hosted on my website.</p> <p>What is the best practice to do this? </p> <p>Obviously I could edit the javascript file remotely without the user needing to change anything - but is that the best method of updating the script?</p> <p>I was thinking of having an Ajax request in the javascript that retrieves output from a php file referencing a mysql database with the text the user wants to change to - however, the same origin policy means that isn't possible.</p> <p>Thanks</p>

    1. COJust as a note, you can use [jsonp](http://en.wikipedia.org/wiki/JSONP) to get around the same origin policy issue.

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.
