在haml的javascript中 调用rails ruby的变量
%html%head :javascript var foo = []; #{ limit = rand(4)+3 array = (0..limit).to_a array.map{ |i| "foo[#{i}] = #{rand(12)};" }.join ' ' } console.log(foo.length); %body在jquery chart中经常会用到，在controller里生成的json变量给jquery的插件读数据
<html><head> <script type='text/javascript'> //<!; foo = 2; foo = 0; foo = 11; foo = 8; foo = 0; foo = 1; //]]> </script> <body></body></head></html>
