Jquery更改事件在coffeescript中不起作用

Question

嘿家伙我刚刚尝试在coffeescript中实现我的更改事件,但它不起作用.有没有人帮我

$('#subscription_id").on "change", -> 
console.log "Hello"
outputs = $(this).val()

if outputs
 $('#subscription_id').prop "disable", "false"
else
 $('##subscription_id').prop "disable", "true"

Answer 1

颜色表明问题:

$('#subscription_id").on "change"

应该是

$('#subscription_id').on "change"
