    <p>I am trying to make a map with <a href="http://www.netzgesta.de/shiftzoom/" rel="nofollow">shiftzoom.js</a></p> <p>I have the following code snippet: </p> <pre><code>function selectall() { for (i in geodata['world']) { var q = getGeoPosition('world', i.toUpperCase(), 1654, 496, 1350, 407); shiftzoom.construct($('world'), [{ x: q.l, y: q.t, w: 40, h: 40, id: geodata['world'][i].lc, pos: 0, title: '', href: "javascript:get_lake(i); ", target: 'graphFrame', src: 'images/bullet.gif' }]); cvi_tip.add(cvi_tip.$(geodata['world'][i].lc), '&lt;small&gt;Province:&lt;/small&gt;&lt;br/&gt;&lt;big&gt;&lt;b&gt;&lt;u&gt;' + geodata['world'][i].ln + '&lt;/u&gt;&lt;/b&gt;&lt;/big&gt;&lt;br/&gt;&lt;small&gt;LAT/LONG:&lt;/small&gt;&lt;br/&gt;&lt;big&gt;&lt;b&gt;' + geodata['world'][i].coord + '&lt;/b&gt;&lt;/big&gt;&lt;br/&gt;&lt;small&gt;PROVINCE:&lt;/small&gt;&lt;br/&gt;&lt;big&gt;&lt;b&gt;&lt;i&gt;' + geodata['world'][i].pr + '&lt;/i&gt;&lt;/b&gt;&lt;/big&gt;'); } } </code></pre> <p>I am positioning dots to represent lakes on the map and I would like it to zoom in when the dot is clicked. This is what the function get_lake does, but every dot I click shows zooms in to the last value of "i". I have tried using closures like so:</p> <pre><code> href:"javascript:function(num){return function(){get_lake(num);};}(i);" </code></pre> <p>but I might not be using it properly since this code doesn't run. Does anyone know how to code it so that the function calls the current variable instead of the last one?</p> <p>Thanks</p>

    1. COThe `href` code won’t get evaluated until the moment you click on the link. The variable `i` will, by then, have a completely different value — if it’s available in that context at all... Much to learn, you have, young Padawan... :-D

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.
