Hi I’m new in rails…I have a problem plz help me…

I’m using Effect.toggle in my code. But it is not working…My code  
is like this…

\<%=link\_to\_function “Toggle this”, onClick=“Effect.toggle( ‘ddiv’,  
‘slide’ ); return flase;”%\>

 this is test content

In mozilla nothing happens even i click the link but in IE it shos  
javascript error like:

Line: 868  
Char: 3  
Error: ‘down( )’ is null or not an object  
…  
…

But the above code works fine if o replace Effect.toggle… by  
Element.toggle… I have downloaded all the latest files  
from [script.aculo.us](http://script.aculo.us)

Plz let me know what is happening…

That should be

> \<%=link\_to\_function “Toggle this”, “new Effect.toggle( ‘ddiv’,  
> ‘slide’ )”%\>

effects are always ran by instantiating a new instance of the effect  
object. On top of that some effects require that the element you’re  
working on have a child element. This can be as simple as an empty span.

Hi Fred thanks for your reply. But I have already done as your  
suggestion like

\<%=link\_to\_function “Toggle this”, “new Effect.toggle( ‘ddiv’,  
‘slide’ )”%\>  
…  
…

But still it doesn’t work. The same problem occurs…Plz help me to  
get rid of this…
