Blocks proceeding with the enter key when getting an answer wrong.
当前为
When doing a Reviews Session on KaniWani, hitting 'Enter' confirms the input, and a second key stroke will let the user continue with the next vocabulary item. However, it might be desirable to only allow proceeding by hitting 'Enter' when the item was answered correctly: if the user gets an item wrong because of a simple typo or a synonym mix-up, the user might hit 'Enter' a second time by accident and loses the chance to correct the answer.
This script prevents exactly that: it disables proceeding to the next item with 'Enter' if the current input was wrong, and the user is forced to click the 'Submit answer' arrow with the mouse to continue.
