尝试在Javascript中使用Rails数组的内容时出现“uncaughtsyntaxerror:Unexpected token<”

在我的硬盘里_控制器.rb:

@locations = Harddisk.select(:location).distinct # grab a collection of distinct harddisk locations objects
@harddisk_locations = []
@locations.each do |location|
  @harddisk_locations << location.location # put only the location names into an array
end

我试图实现将Rails的@harddisk\u locations的内容加载到Javascript的harddisk\u位置:

var harddisk_locations = [<%= raw @harddisk_locations.to_json %>];

未捕获的语法错误:意外的标记<

我想Javascript是在抱怨

刚好在…之后
