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

Can you please give another solution to this problem? I have to replace a div if that div exists. So first I have to check the existence of div. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
