如何使用 jQuery 检查在单击事件期间是否按下了某个键? [英] How can I check if a key is pressed during the click event with jQuery?

问题描述

我想用 jQuery 捕捉点击事件，并且能够判断是否同时按下了某个键，以便我可以根据按键事件在回调函数中分叉.

I would like to catch a click event with jQuery and be able to tell if a key was pressed at the same time so I can fork within the callback function based on the keypress event.

例如:

$("button").click(function() {
    if([KEYPRESSED WHILE CLICKED]) {
        // Do something...
    } else {
        // Do something different...
    }
});

这完全可能吗，或者如果可能的话怎么做?

Is this possible at all or how can it be done if it is possible?

推荐答案

您可以轻松地从事件属性中检测 shift、alt 和 control 键；

You can easily detect the shift, alt and control keys from the event properties;

$("button").click(function(evt) {
  if (evt.ctrlKey)
    alert('Ctrl down');
  if (evt.altKey)
    alert('Alt down');
  // ...
});

有关更多属性，请参阅 quirksmode.如果要检测其他键，请参阅 cletus 的回答.

See quirksmode for more properties. If you want to detect other keys, see cletus's answer.
