Bug 13645 – JSEnv bookmarklet doesn't print errors

• Component: WebKit Website
• Status: RESOLVED DUPLICATE

[Garrett Smith]

JSEnv is a very useful development bookmarklet that does not work in Safari.

I don't expect the feature "install as user script" to work.

However, JSEnv cannot run a simple script in Safari.

Try in FireFox to see how it should work.

Hi Garrett, JSEnv seems to work fine in the nightlies.  If you are seeing a particular problem please reopen the bug.  Thanks for the report though.

Much better in the nightly. However, running the example in Safari, the failure case has a different Result: The error does not make it to the console, as it does in FireFox. I didn't try to find out why the failure test failed.


In firefox:
================================================
Running...
Squares of numbers 0 through 4:
0
1
4
9
16
Error on line 11: this.statement has no properties
================================================
In safari:
================================================
Running...
Squares of numbers 0 through 4:
0
1

================================================

Confirmed with a local debug build of WebKit r21332 with Safari 2.0.4 (419.3) on Mac OS X 10.4.9 (8P135).

JavaScript console reports (when running the "failure" test):

TypeError: Undefined value
Line: 11

This problem is caused by window.onerror not working in WebKit, closing as a duplicate.

Thank you for reporting this! Please file new bugs if you find any other problems with this bookmarklet.
