If using document.getElementsByTagName("script") in a script that is being generated within the <head>, the first time the command is executed, it returns the current list of scripts loaded.
However, for all subsequent calls, the same list is returned as the first time the call was made and this only seems to correct itself once the load is complete (ie by onload, all of the script elements are found)
NOTE this is a simplified example and I believe could be related to a timing issue. I have had examples where this works - especially if using the debugger.
Reproducible: Always
Steps to Reproduce:
1.have a javascript file call document.getElementsByTagName("scripts")
2.have a second JS file do the same thing
Actual Results:
1. Will list all of the scripts included so far, including the current script.
2. Does not show any more scripts - only the previous list of files
Expected Results:
1. Will list all of the scripts included so far, including the current script.
2. Shows newly included files
The easiest workaround is to include the scripts and run the getElementsByTagName once they have been included.
This may affect script.aculo,us and any other libraries that try and dynamically load libraries as the main install script does search the existing scripts.
This contains several included js files, each of which performs a document.getElementsByTagName("scripts") and lists in an alert box the current list.
Note that I have run this test several times and mostly it will not show more than f4 and f1 until the HTML list in the <body> and the onload alert. However I have had experiences whereby the during the load of f3, all of the files are shown. This is however intermittent

This testcase can be viewed online.
I can see the bug on branch, but not on trunk anymore, so it seems to be fixed by something.

So this seems to be fixed between 2006-05-12 and 2006-05-13:

It seems to me this was fixed by bug 332644. Right, Boris?
Flags: in-testsuite?
