Forum: Rails Spinoffs (closed, excessive spam) prototype problems in IE

i'm currently developing a web application with the goal, that
everything should work in as many browsers as possible. im using
prototype and the first barrier is IE (as expected). The problem ist
the following:

...
scroll = document.viewport.getScrollOffsets();
...
throws: "Object does not support this method"


another problem is that:
...
e.up(1).getElementsBySelector('li.menu').each(function(i)
{i.removeClassName('active');});
...

doesn't work, but:

Element.up(e, 1).getElementsBySelector('li.menu').each(function(i)
{i.removeClassName('active');});

works fine...

As usual everthing works fine in firefox and other "better" browsers.

Can anybody give me a hint?

Regards
Daniel

You have an element that isn't extended.  Wrap your e element in a $():

$(e).up(1)....

Besides what Fred said, #getElementsBySelector has been deprecated -
use #select instead.

$(element).up(1).select('li.menu').invoke('removeClassName',
'active');

thanks for quick response, after extending the element everything
works.

But why does the viewport function not work?

> But why does the viewport function not work?

Usually this is because you're trying to use it before Prototype is
loaded or before the DOM is ready.  Can you post a trimmed-down
example demonstrating the problem?

unfortunately its an intranet application and i can not post an
example..

i tested if the function exists by using:

alert(document.viewport.getScrollOffsets);

and the function would be alerted as seen in prototype.js and more
confusing is that the getDimensions() method would be called without
any error just a line before getScrollOffsets().

prototype is the first js file that is been loaded:

  <script type="text/javascript" src="/scripts/prototype.js"></script>
  <script type="text/javascript" src="/scripts/global.js"></script>
  <script type="text/javascript" src="/scripts/subwindow.js"></script>
  <script type="text/javascript" src="/scripts/actions.js"></script>

and the problem lines are located in subwindow.js

Hi,

That shoudln't prevent your creating a stripped-down example
demonstrating the problem; we don't need to see your app, just
something showing the problem you're having.

I'm suggesting this for two reasons:

1. Usually, if you go through the steps necessary to create a simple
test case, you find the problem. :-)

2. If you don't find the problem, you can post your code so folks can
help you out.

For me, easily 75% of the time, I find my own answer at Step #1 and
don't have to move on to Step #2.

FWIW.

okay i understand thats hard to find a error if theres no example
other problematic code. but the problem is that there are to many
conditions to make a small example.

i checked the function it self, and as you mentioned above the problem
seems to be that the document is not loaded 100%, even if the browser
says its done.

i found a workaround and maybe i'll find the problem it self too.

thanks for helping

Hi,

Glad you found a workaround, anyway.  If you find the actual problem,
it'd be cool to know what it was.

Enjoy,
