 Posted: Sun Aug 25, 2002 3:10 am Post subject: Hints: Turning on Error Messages |
 |
|
We often have questions like this in our forum: | Quote: | | I wrote the following script and nothing at all happens when I view it in a browser. |
In cases like this, if nothing is really happening at all, JavaScript might be turned off in the browser. But more likely, your browser is simply not configured to display error messages. When you're debugging a script, be sure you turn on error messages so you'll have all the information you can get about your script's problems.
Here's how to enable error messages in Internet Explorer:- From the menu, select Tools | Internet Options.
- Select the Advanced tab at the top of the dialog.
- Uncheck the Disable script debugging option.
- Check the Display a notification about every script error option.
- Click OK to save the settings.
You might find these error messages annoying (and surprisingly common) when visiting other people's sites. That's why I keep the errors disabled. When they're disabled, you'll see a tiny red ! icon in the IE status bar when an error happens - double-click on this icon to display the error message.
In Netscape, errors are displayed on the JavaScript Console. You might need to view the console to see them. Type javascript: into the address field in most versions of Netscape to view the console. If this doesn't work in your version, try selecting Tasks | Tools | JavaScript Console from the menu.

Neat trick, that. Works in Mozilla (which Netscape really is just a re-branded version of), too.

I use Firebug http://getfirebug.com/
There are now (more or less) equivalents in all browsers now.
IE developer tools
Opera Dragonfly (Built in)
WebKit (Google Chrome / Safari) developer tools / inspector (Built in)
Interestingly, the contributions Google make to the tools for Chrome are contributed back to WebKit, so they will appear in Safari over time.

| One is always Dragonica Gold on a strange road, watching strange scenery and listening to strange dragon nest gold music. Then one day, you will find that the things dragonnest gold you try hard to forget are already gone. |
