rails simple formでbooleanのvalueをjQueryでgetする方法

Posted at

jqueryでcheckされたかをどうやって実装するか悩んで調べましたが、あまり情報がなく自分で実装してみました

# rails form, idは"testBool"とします
= f.input :test_bool, as: :boolean
 
// jquery
$('#testBool').on('click', function() {
  console.log($(this)[0]['checked'])
})
 
-> 
false
true
 

この実装方法でいけば動的にtrue, falseを取得することができるのでjs側での制御がかなり楽になります
