Hi all,

Can I have a ruby code inside a java script function written in .js file?

When I tried it, i got an error.

e.g. consider following function inside myscript.js file

myscript.js

function sayHi

{

<%name=“xyz”%>;

alert(‘HI <%=name%>’);

}

But this works if I have above function in a rhtml file inside tag.

Any inputs in this regard will be really helpful.

Thanks and Regards,

Medha.

no, you cannot have ruby code inside a standalone js file, as it is
your browser that requests the file directly from the webserver. it
is NOT being parsed/interpreted/executed on the server.

when you put the ruby code into the rhtml template within <script>
tags then that code IS being parsed as part of the template file.

Yes and no. You can't have Ruby code within a .js file stored in the public directory, but you could generate a javascript file from a controller (this will require some disabling any layouts, etc.). Your HTML will probably need to reference the generated javascript "file" directly, rather than through Rails' helper function.
