[OpenLayers-Users] External use of proj4js?

[Mike Adair]

Hufjan,

It looks like the SRS input fields on that form need an onchange event 
to load the projection definition, i.e. just typing in a SRS code in the 
field doesn't create the Proj4js object required, that only gets created 
by selecting a code from the drop down list. 

We can fix that, but if you want to get it working now, you will need a 
local copy of Proj4js and then:
- add a file for EPSG:25833 in lib/defs and use this as the content: 
http://spatialreference.org/ref/epsg/25833/proj4js/
- in test.html, include that def file using the script tag:
<SCRIPT type="text/javascript" src="lib/defs/EPSG25833.js"></SCRIPT>

That will get that projection into your drop down list and then the form 
should work.
