  3. To use the console, open Safari and in the menu bar choose Develop > Show Error Console.

  4. Close the console by clicking the close button on the right hand side of the error consoles menu bar.


Firefox

Firefox comes with its own built-in web console.


Mac OS X

  1. Open Firefox and choose Tools > Web Developer > Web Console.

  2. Refresh the web page.

  2. Choose Web Developer > Web Console.

  3. To close the Console click the Close button found on the right hand side of the Consoles menu bar.


TIP: There is a powerful add-on for Firefox called Firebug, this enhances the console and makes finding faults easier. In the video above, in the second error example which used a back slash, Firebug actually shows the back slash as well as displaying the URL encoding of it.


Google Chrome

Google Chrome calls this, Developer Tools.


Mac OS X

There are a few ways to access the Developer Tools.

(To close the Developer Tools click the Close button found on the left hand side of the Developer Tools menu.)


Windows

  1. Open Google Chrome and choose Customize > Tools > Developer Tools.

  2. To close the Developer Tools click the Close button found on the right hand side of the Developer Tools menu.


Internet Explorer

Internet Explorer calls this Developer Tools. Unlike the other web browsers, Internet Explorer cannot detect what is happening in the Flash player so you will not get any errors. It is recommended that you use one of the other browsers for error hunting. However, it is still useful for other diagnostic reasons.


  1. Click Tools > F12 developer tools. The Tools button is located the right of the address bar.

  2. To close the developer tools click the Close button on the right in the developer tools menu.


Using the Error Console

To show the consoles working here are three links each with an error.

http://support.ggno.me/error/error_1
http://support.ggno.me/error/error_2
http://support.ggno.me/error/error_3


Error_1 does not have its javascript file (swfobject.js) uploaded to the server, so the SWF cannot be displayed.

Error_2 has a subfolder called, pano, that contains the SWF. The file path is using a backslash instead of a forward slash.

Error_3 has a simple capitalization error.


Error_1 opened with Safari on Mac

When the Error Console is first opened make sure Console is selected and All in the consoles menu bar. It is also recommended to refresh the page.

This looks as if Adobe Flash is not installed, but the console is showing it can not find the file swfobject.js on the server.


Error_2 opened with Firefox on the PC

The page will open without an error, so click the hotspot and the console will show the error as it tries to open the next panorama.

Error console 05.png

The above image is showing that rather than a forward slash, / between the file names, it has %5C which is the URL encoding for a backslash \. So, in the Hotspot Editor the wrong slash was used.


Error_3 opened with Google Chrome on the Mac

This panorama worked before uploading to the server.

Error console 06.png

The above image is showing that when the point hotspot was clicked the panoramas did not change and an error was displayed. When clicked, the point hotspot wass looking for Pano_02.swf. However, on the server the file is pano_02.swf. When tested locally hotspots are not case sensitive, even running through the web server, but once uploaded they are.
