JavaScript Error In post.js When Using Internet Explorer

[brianwhite]

When using Internet Explorer (but not Firefox) I receive the dreaded error "Object doesn't support this property or method" I traced the error to line 217 of post.dev.js. Evidently, IE doesn't like the way the autosave function is declared inside of the if statement. The solution was to replace "autosave = function(){};" with "var autosave = function(){};" There were no problems in Firefox regardless of how autosave was declared. It was a simple change, however, I have still attached a patch with the above change.

Steps to reproduce. Access any admin page where post.js will be loaded and autosave.js is not using Internet Explorer.

@brianwhite - andrew is having issues reproducing, and, please try this:

document.autosave = ...

Or window.autosave = ... as autosave is supposed to be in the global scope.

Using Internet Explore 8 on Windows Vista.

• Everything worked fine when using document.autosave.
  
• Everything also worked fine when using window.autosave.
  

I do not know why IE doesn't like autosave by itself. Neither prefix should be required.
