1. Develop with full library, & I tend to use the full debug versions. Yes, it makes your code load much slower and the 20-30s page reload times can get tiresome, but if you encounter an error, using the debug versions will let you find where you are going wrong.
2. IE8 & IE9 have built-in debugger that is very similar to the WebKit (Safari / Chrome) Developer Tools. If you want even more control and want a full featured debug environment, Visual Studio Web Developer Express is an EXCELLENT debugger. VS WebDev Express is available for free from Microsoft (along with all their other "Express" products). I wish there was a way to get it to attach to non-IE browsers because it is a truly awesome debugger. You can use the VS debugger in IE7 & (good god, no!!!) IE6 as well which don't have an integrated debugger. Hope that helps Matt Priour Kestrel Computer Consulting From: Robert Buckley Sent: Monday, January 24, 2011 2:23 AM To: [email protected] Subject: [Users] Advice regarding optimization and debugging Good Morning, Could someone please offer some advice regarding... 1. How to successfully reduce the loading time of a geoext/openlayers project. I am aware that the loading time of these libraries takes up to between 5 - 10 seconds. Therefore... should I look through my code after the project is completed and note which controls have been used and then create a customized openlayers js library or do you generally plan a project with the tools and controls already defined and create the openlayers.js before you start programming? In my experience (which is very limited) I start programming with the whole openlayers/geoext/ext libraries so that when I need to add something which was not planned before hand, I don´t have to worry about loading new code into the js library. Assuming this is the way most programmers start, which method do you use to remove unused scripts? 2. Debugging a project. I am using Aptana (free version) and firefox with firebug to develop. This combination works great....until I open the project with Internet Explorer and discover that nothing works! Does anyone have any tips regarding writing code which can be used to simultaneously debug in Firefox and IE? I find that most errors are forgotten commas, but occasionally there are undfined objects which show up in the ie developer tool bar as errors in the openlayers.js code. These errors are the worst as there is not direct link to the code in my own scripts? Does anyone have any IE debugging tools which help? How do you get around these problems? Anyone used Chrome to debug? Thanks for any replies/comments/suggestions, Yours, Robert Buckley -------------------------------------------------------------------------------- _______________________________________________ Users mailing list [email protected] http://www.geoext.org/cgi-bin/mailman/listinfo/users
