    <p>i'm using a library that creates svg content using raphael library. I would now like to add zooming functionality. I found following library:</p> <p><a href="http://www.cyberz.org/blog/2009/12/08/svgpan-a-javascript-svg-panzoomdrag-library/" rel="nofollow">http://www.cyberz.org/blog/2009/12/08/svgpan-a-javascript-svg-panzoomdrag-library/</a></p> <p>This is how the svg part looks:</p> <pre><code>&lt;svg xmlns="http://www.w3.org/2000/svg" version="1.1"&gt; //...the image </code></pre> <p>The issue is that this library expects a script tag and a g tag surrounding the whole image. It should look like this after manipulation:</p> <pre><code>&lt;svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1"&gt; &lt;script xlink:href="SVGPan.js"/&gt; &lt;g id="viewport" transform="translate(200,200)"&gt; ...//the image &lt;/g&gt; </code></pre> <p>I would need to add the script tag but the real problem is to put a g element with id="viewport" around the whole rest of the image. How can i do that with JQuery or plan JavaScript?</p> <p>EDIT:</p> <p>I got a bit ahead of myself. It turns out that adding the script tag does not seem to work:</p> <pre><code>var svg = $('svg'); svg.attr('xmlns:xlink', 'http://www.w3.org/1999/xlink'); // else error in firefox with links var scriptElement = document.createElementNS('http://www.w3.org/2000/svg','script'); scriptElement.setAttribute('xlink:href','js/SVGPan.js'); svg.prepend(scriptElement); </code></pre> <p>I don't get an error and the script runs completely but the tag is not added. I have verified that $('svg') selects the desired element and I can do stuff with it except prepending the script tag for whatever resaon i do not understand.</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.
