Hi all,<div><br></div><div>I've tweaked the script a little and added the markers layer in advance of the jquery function. It's beginning to dawn on me that what's going on is that the jquery fired portion of the script isn't accessing some of the OL functions, and is passing null data, or that's the closest to a reasonable solution I can think of...</div>
<div>The error I'm getting now is "<span class="objectBox objectBox-errorMessage hasBreakSwitch "><span class="errorMessage ">c.getCode is not a function" reference to OL line 311.</span></span></div><div><span class="objectBox objectBox-errorMessage hasBreakSwitch "><span class="errorMessage "></span></span>Any ideas?<br>

Hi all,<div><br></div><div>I've hacked together a geolocation script using the OpenLayers demo, a tutorial on Mobile Tutorials <a href="http://mobile.tutsplus.com/tutorials/mobile-web-apps/html5-geolocation/" target="_blank">http://mobile.tutsplus.com/tutorials/mobile-web-apps/html5-geolocation/</a>, and a couple of other OL-Geolocation demos out there. Independently, I've gotten the parts of the script to work, but I'm not sure what's happening here when bring them all togehter and use jquery for my button firing. </div>
<div><br></div><div>The script calls the initGIS function onLoad loading a simple map set to a lonlat. The button then fires the geolocation script, which uses modernizr to check for geoloc support, provides error checking and olderbrowser support via YQL (maybe I should use the MIT-license geo.js? suggestions). The script was breaking on adding the markers, but I realized that I had to declare some of the variables as globals. The issue now is a rather opaque error in the OL code saying "<span style="color:rgb(255, 0, 0);font-family:Consolas, 'Lucida Console', monospace;font-size:12px;line-height:12px;white-space:pre-wrap">Uncaught TypeError: Object function (){var a=null;if(this.baseLayer!=null)a=this.baseLayer.projection;return a} has no method 'getCode'"</span></div>
