As a slightly more general solution, rather than wrapping the "" around the erb block, if you call inspect on the object inside then it will have quotes added if it's a string but not if it's a number, and if it's an array it will be shown in the right format, etc. So, .inspect makes things print out in such a way that they 'look right' and can be used as is. (In the example above it looks like you need a number rather than a string. ) #in rails controller @cars = Car.find(:all) #in your js section in a view page var carNames = <%= @cars.collect(&:name).inspect %>; => var carNames = ["Micra", "Primera", "Almeira"]; var firstCarModel = <%= @cars.first.model.inspect %>; => var firstCarModel = "Nissan"; for(var j=0; j < <%= @cars.length.inspect %>; j++) => for(var j=0; j < 3; j++) -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
