passing ruby variables to javascript (Ruby on Rails)

I have a list of medicines and a list of vaccinations that I am extracting from tables medicines and vaccinations respectively. The list of medicines is of the format medicine_name and so is the list of vaccinations. I store both of these in vars using this piece of code. ``` var injections=<%=@injections%>; var medicines=<%=@medicines%>; ``` In my view I have select tags for medicines and injections but when I try to append these vars to the respective tags using the following code. I don't get any results please help ``` $('.addmedicines').click(function() $('.medicines').append(medicines); }); $('.addinjections').click(function(){ $('.injections').append(injections); }); ``` Here .injections is the class assigned to select tag for vaccinations. .medicines is the class assigned to select tag for medicines. And .addmedicines and .addinjections are html buttons. EDITED: When I try to display both injections and medicines in javascript they display like this: Medicines: ``` <option>Med1</option><option>Med2</option><option>Med3</option><option>Med4</option> ``` Injections: ``` <option>i1</option><option>i2</option><option>i3</option><option>i4</option> ```
