<p>window.scrollMaxY can be set via that property in IE and older versions of Firefox, but when trying in FF3 it says "Cannot set this property as it only has a getter".</p>

<p>What is my alternative?</p>

<p>EDIT:</p>

<p>The reason why I'm asking is that I'm fixing some very horrible JS written by someone else, it has a function to keep a div centered on the page while scrolling, and has this line:</p>

<pre><code>// Fixes Firefox incrementing page height while scrolling
window.scrollMaxY = scrollMaxY
</code></pre>

<p>Obviously this doesn't work, but the main issue is that when the page is scrolled, it grows in length.</p>

First, I'm not sure that naming your function
```
t
```
is helping as 't' is used as the
truth value
in lisp.
That said, the following code works for me:
```
```
(defun test-func-1 ()  "test-func-1"
   (interactive "*")
   (insert-string "testing callers"))

(defun func-caller (callee)
  "Execute callee"
  (funcall callee))

(func-caller 'test-func-1)
```
```
Please note the use of 'funcall', which triggers the actual function call.
