我在views / touches / new中的表单中有一个select字段：

我试图在assets / javascripts / touches.js.coffee中调用函数“populate”
<%= f.select :touch_type, options_for_select(['Attack',
'Block','Pass', 'Set']), {include_blank: "Select touch type..."
:onchange => 'populate()'}, class: "form-control" %>
...这样它将填充此选择字段，其中包含特定于此处所示第一个选择字段中所做选择的选项：
jQuery ->
populate = ->
s1 = $('#touch_touch_type_id').html()
s2 = $('#touch_touch_result_id').html()
s2.html = ""
if s1.value == "attack"
optionArray = ["score|Score", "out|Out"]
for option in optionArray
pair = optionArray[option].split "|"
newOption = document.createElement "option"
newOption.value = pair[0]
newOption.html = pair[1]
s2.options.add newOption
当我在第一个选择字段中更改选项时，没有任何反应。我尝试了一种名为“yell（）”的测试方法，看它是否称之为但仍然没有运气。
<%= f.select :touch_result, {}, {include_blank:
"Select touch result..."}, class: "form-control" %>
不完全确定我的错误所在。
感谢任何帮助。
