Use array.to_json and send it over to the client. For example, you could use an AJAX call to do that. - Aleksey On Jan 18, 5:30 pm, Prashant <prashant.thak...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Hi, > > How can we use an array created in Ruby in Java script ? > > Regards, > Prashant-- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I tried using json but I am doing some mistake because of which I am
not able to get value properly I have such code in ruby file
@files = Dir.glob("*.txt").to_json
In view file
var files= (''<%= h @files -%>'');
When I see the alert I get a complete string containing list of all
files When I run this alert I see one character printed at a time iso
a single file name.
for(i=0;i<3;i++)
{
alert(files[i]);
}
I am making some mistake in using json but could not figure out what.
Can you please help ?

Then you should be able to work out what is wrong. Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

So var files = ["bla","blubb"]; is syntactically wrong. Should be: var files = ["bla","blubb"]; This means: never use h (<%h %>) for Javascript.

Instead, put the JSON in a hidden div in your HTML, then have your JS read it from there. This will avoid mixing JS and HTML.> > Regards, T.Best, -- Marnen Laibow-Koser http://www.marnen.org marnen-sbuyVjPbboAdnm+yROfE0A@public.gmane.org -- Posted via http://www.ruby-forum.com/. --0022158df84f3d1bde047d71424c Content-Type: text/plain; charset=ISO-8859-1 -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
