Identify results from different location

DavidBoyd · ‎09-21-2012

I'm VERY new to Jaxascript and working on my first web map. The identify tool kind of works, but it returns results from a different location than where I click. Also, the pop up sometimes spills off of the map page and isn't fully visible. I think this has to do with the size of the map window or my tabs to the left, but I'm not sure how to fix it. Any suggestions are very appreciated. My very messy script will follow:

David,

The issue with the map identify location being offset was probably due to the fact that the html that defined the identify window tab content was above the map and causing a positioning offset. Since the tab container is used by the info window I modified your app to build it through code instead. There was also some duplicate code, adding layers twice, multiple load event listeners etc which I removed from the app. Here's the revised version:

David,

The issue with the map identify location being offset was probably due to the fact that the html that defined the identify window tab content was above the map and causing a positioning offset. Since the tab container is used by the info window I modified your app to build it through code instead. There was also some duplicate code, adding layers twice, multiple load event listeners etc which I removed from the app. Here's the revised version:

Kelly,

Thanks so much for editing my code and doing some clean up! Unfortunately I am having trouble getting the the basemap and other layers to load. I corrected a typo in the one of the variables (var riversResutls) and I'm looking for possible other issues. If you have any ideas let me know...otherwise I'll keep looking until I figure it out.

Thanks again! David

If you debug your app using Chrome Developer Tools or Firebug do you see any errors in the console?

KellyHutchins · ‎09-24-2012

Just re-read your first post and saw that you said you were new to JavaScript so here's a link to Firebug if you haven't used it before:

https://getfirebug.com/enable

I highly recommend spending a bit of time becoming familiar with either Firebug or the Chrome Dev tools they make debugging JavaScript apps much easier. They allow you to view errors and messages in the console, set breakpoints and step through your code, inspect the css and much more.

DavidBoyd · ‎09-24-2012

I'm looking at it in Firebug right now. I do need to get more familiar with it and now seems like a good time. Thanks!
