防止在选择中向右/向左箭头导航 [英] Prevent right/left arrow navigation in select
问题描述
我有3个选择可以启用键盘导航(左右箭头键)在它们之间移动.按向右或向左箭头键时的默认行为是向上/向下移动列表.
I have 3 selects that I am enabling keyboard navigation(right and left arrow keys) to move between them. The default behavior when pressing the right or left arrow key is to move up/down the list.
我的解决方案可以在选择之间移动，但是每次您移动到新选择时，刚刚移动的选择中的所选值都会根据您按下的箭头向上或向下移动.
My solution works moving between the selects, but every time you move to a new select, the selected value in the select that you just moved from gets moved up or down depending on which arrow you pressed.
有没有一种方法可以防止选择的默认左右箭头键?我已经尝试过e.preventPropagation和e.preventDefault，但这似乎不起作用.
Is there a way to prevent the default right and left arrow keys for the selects? I have tried e.preventPropagation and e.preventDefault but that doesn't seem to work.
推荐答案
我刚刚弄清楚了.当我需要绑定到keydown事件时，我正在绑定keypress事件.绑定到keydown时，可以使用e.preventDefault().
I just figured it out. I was binding to keypress event, when I needed to bind to the keydown event. When binding to keydown then you can use e.preventDefault().
