Hi

  From an rjs file, I called a javascript function in ci.js as follows:       page.call 'test',params[:id]+'parents'

  In ci.js I wrote the following:       function test(div_name) {          alert("testing........" +div_name)          if ($(div_name))          {           t=1;           return t;          }          else          {           t=0;           return t;          }      }

  Now in the rjs file I have to get the value of t which is returned from the function test in ci.js.

  How can I get the value of t? Please help.

Thanks Suneeta

You can't. the rjs file is evaluated server side, but the javascript
is executed on the client at a later state (except of course in the
sense that your rjs can assign the result of that function call to
another javascript variable, pass it as an argument to another
javacsript function etc..., but there's still the server/client
boundary that can't be crossed).

Other than what I said when you asked yesterday, no.
