Hi everyone!

I’m tearing my hair out over an RJS problem. I’ve used it before  
without issue, but I’ve no idea what is going wrong here. I’m trying  
to display a div which starts off invisible defined with:

...

In my .rjs I have:

page.call("$(‘block1’).show()")

When I run this, Firefox displays block1 but then gives me two errors:

1. “Type error $(“block1”).show() is not a function”
2. $(“block1”).show()()

Any help would be appreciated!

</div>

I’ve discovered that an easier way to do this is:

page.show(‘block1’)

No idea why my first attempt half worked.

</div>

Also,

page[‘block1’].show

works as well. I often prefer the proxied commands like that one. i.e

page[‘block1’].replace\_html vs page.replace\_html ‘block1’
