#2975 closed defect (fixed)

IE7: dojo does not load from local filesystem when isDebug: true

Reported by: guest Owned by: Jared Jurkiewicz
Priority: high Milestone:
Component: General Version: 0.9

Blocked By: Blocking:


Dojo version:
profile=base, built from current 0.9 development sources of revision 8529

IE7 only, does not occur with IE6, Firefox 2.0

Steps to reproduce:

  1. Save the attached file, isDebug_true.htm, to the local filesystem
  2. Build dojo, place it into dojo subfolder; place firebug files into dojo/_base/firebug/
  3. Launch IE7, open the file; if asked, allow the script to run
  4. The page prints "dojo.byId: undefined"

Expected result:

  1. "dojo.byId: function("...

This behavior is caused by what is already described in ticket #1711, but that one is against dojo 0.4/0.5. The following line in hostenv_browser.js throws an error, preventing further loading of dojo:


Turning off "Native XMLHttp support" in advanced options of IE7, as suggested by ticket #1711, is a workaround.

Patch to fix the issue against dojo 0.9, in /_base/loader/hostenv_browser.js, after the following line: (line 78, as of rev.8529)

			try{ http = new XMLHttpRequest(); }catch(e){}

add something like the following lines:

			if(dojo.isIE && location.protocol=="file:"){
				http = null;

It would be more efficient just to avoid that

try{ http = new XMLHttpRequest(); }catch(e){}

call in the above case, instead of "null"ing its result. Also, '==' in strings comparison can be replaced with '==='.
