如何使用jQuery单击事件期间检查是否按下了键? [英] How can I check if a key is pressed during the click event with jQuery?

问题描述

我想用jQuery捕获click事件，并能够判断是否同时按下了一个键，这样我就可以基于keypress事件在回调函数中进行分叉.

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...
    }
});

这完全有可能吗?如果有可能怎么办?

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，请参见 quirksmode .如果要检测其他键，请参见

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