JQuery或JavaScript：如何在单击锚标签超链接时确定是否按下了shift键？ [英] JQuery or JavaScript: How determine if shift key being pressed while clicking anchor tag hyperlink?

问题描述

我有一个调用JavaScript函数的锚标记。

I have an anchor tag that calls a JavaScript function.

无论有没有JQuery，如何在点击链接时确定shift键是否关闭？

With or without JQuery how do I determine if the shift key is down while the link is clicked?

以下代码不起作用，因为只有按下真实键（不是shift键）才会触发按键。 （我希望如果仅按下shift键就会触发。）

The following code does NOT work because keypress is only fired if a "real key" (not the shift key) is pressed. (I was hoping it would fire if just the shift key alone was pressed.)

var shifted = false;

$(function() {                           
    $(document).keypress(function(e) {
        shifted = e.shiftKey;
        alert('shiftkey='+e.shiftkey);
    });

    $(document).keyup(function(e) {
        shifted = false;
    });
}

...

function myfunction() {
  //shift is always false b/c keypress not fired above
}

推荐答案

    $(document).on('keyup keydown', function(e){shifted = e.shiftKey} );
