Pass Ruby Array to Javasript Problem

Rails
1

I have an array named weight_array. Now i want to pass it to my
javascript function abc… How can i pass it … May be a stupid question
but did’nt find it by googling also …

Currently i am doing like this.
<%= radio_button “ab”, “cd”, { :onclick => “abc(weight_array)”; } %>

Tried this also …
<%= radio_button “ab”, “cd”, { :onclick => "<%= abc(weight_array) %> ";
} %>

Tried this as well …
<%= radio_button “ab”, “cd”, { :onclick => “abc(weight_array.to_json)”;
} %>

Also after resolving it, i want to know that if i need to pass the ruby
array with join function …then how can we pass …
I mean the function [ weight_array.join(", ") … ] …

Need to know each and every possible answer …

Please clarify, abc is the javascript function and weight_array is the
ruby
array, right?

Although I know very little javasacript, but try this as well:

<%= radio_button “ab”, “cd”, { :onclick => “abc( " + <%= weight_array
%> +
" )”; } %>

BTW, you should use join to make weight_array a string before passing to
javascript function. You can recreate the array in javascript, if you
wish,
by splitting back.

Did you try converting weight_array into a string first? Because
javascript does not understand ruby objects.

Use JSON for passing array data between Ruby and Javascript. I think
you missed the #{} inside the string above.

<%= radio_button “ab”, “cd”, { :onclick => “abc(#
{weight_array.to_json})”; } %>
