その「３」は、おそらく30を入力する途中、消す途中の「３」です。なぜこのような中途半端なタイミングで発火してしまうのか分かりません。

記述やイベント発火させようとしているフォームが多いため、
|
|
22
|
-
今回はそのエラーが起きる部分のイベント発火の部分のみ記載します。
|
|
23
|
-
|
|

その他のフォーム・イベント発火にも関連して問題がありそうな場合、追記しますので教えていただけますでしょうか。

### 該当のソースコード
|
|
31
|
-
前提として、今回作成中のアプリは割勘計算機能です。
|
|
32
21
|
|
|
33
|
-
total_payment（総支払額）とtotal_people（総人数）は前提条件のようなもので、このフォームに入力された値をもとに、様々な計算を行います。
|
|
34
|
-
|
|
35
|
-
そのほかにグループを三つ用意しています。
|
|
36
|
-
|
|
37
|
-
group_people_two、group_price_two、group_ratio_two
|
|
38
|
-
上記はグループ2の、左から順に人数、料金、比率の値を入れていくフォームです。
|
|
39
|
-
|
|
40
|
-
group_people_three、group_price_three、group_ratio_three
|
|
41
|
-
上記はグループ3です。
|
|
42
|
-
|
|
43
|
-
group_people_one、group_price_one、group_ratio_one
|
|
44
|
-
上記はグループ1ですが、グループ1のみ入力フォームではなく出力するために用意しています。
|
|
45
|
-
前提条件からグループ2と3の数値を引いて、グループ1に表示させようとしています。
|
|
46
|
-
|
|
47
|
-
price（料金）とratio（比率）に関しては、一方に値を入れた時、もう一方の値が自動で表示されるようにしています。
|
|
48
|
-
この部分で、今回の問題が発生しています。
|
|
49
|
-
|
|
50
|
-
indivisible_numberは余った値を出力しようとしています。
