app,ication.js is a good place for some general purpose scripts,  
that are used by all (or most) of your views  
don’t forget to use:  
\<%= javascript\_include\_tag :defaults %\>  
in the header section of your layout

but you can use your own js files as well, place them in public/  
javascripts  
and (assuming myscripts.js is the filename:  
\<%= javascript\_include\_tag ‘myscripts’ %\>

> and how can i call it

say you have defined a js function like  
function doSomething() {  
alert(‘hello world’);  
}

in a file & included it as described above, then it will be available  
as any js from your page. There are many ways to call this function  
for

one of the most simple:  
\<%= link\_to\_function(“hello”, “doSomething()”) %\>

will create a link and call this function.  
But you can use it as event handler in onclick, call it directly from  
any other function  
and so on.
