\<%= javascript\_include\_tag “jquery.js” %\>

I want to add class to table tag using following command inside  
script tag.

CSS has all the tree class declared  
.odd {  
background-color: #fcc;  
}

.even {  
background-color: #cef;  
}

.table-heading {  
font-size: 12px;  
}

CSS is linked properly and if I add class manually I can see the  
stylesheet applied to the page.

But I cannot get the alert neither I can see the class in

 tag.

I am a newbie to rails.  
any help is appreciated.

Thanks in advance

Shouldn’t that be \<%= javascript\_include\_tag ‘jquery’ %\>

You could probably easily discover whether your jquery file is being  
loaded by using Firebug, btw…

Thanks Hassan S.,

The File is loaded correctly.  
And I tried both \<%= javascript\_include\_tag ‘jquery’ %\> \<%=  
javascript\_include\_tag “jquery.js” %\>  
And both load the file correctly.

Moreover I can see the JavaScript (JQuery.js) loaded using firebug.

Still No luck.

Thanks

yeah, if you still have javascript\_include\_tag :defaults, prototype  
will still get loaded

If you want to keep prototype loaded though (to take advantage of  
Rails builtin AJAX functionality for example),  
[http://docs.jquery.com/Using\_jQuery\_with\_Other\_Libraries](http://docs.jquery.com/Using_jQuery_with_Other_Libraries) will be of  
use

The problem was the case of addClass.  
Changing addclass to addClass did the trick.  
Thank you very much guys for all your help.

Are you sure you are not including prototype.js?
