如何同时检测按键和鼠标悬停 [英] How to detect a keypress AND a mouseover at the same time

问题描述

好的，我可以使用 .on（'mouseover'）

检测鼠标悬停，我可以检测到按键使用

and I can detect keypresses using

$(document).keypress(function(e) {
        console.log(e.which);
}

但是当我按下时如何检测鼠标悬停在哪个图像上？某个按钮？

but how do I detect which image my mouse is hovering over when I press a certain button?

这个想法是能够在将鼠标悬停在d上时删除图像。任何想法？

the idea is to be able to delete an image by pressing d while hovering over it. any ideas ?

推荐答案

您只需切换显示当前正在徘徊的类或数据属性

You can just toggle a class or data-attribute that shows you which one is currently being hovered

$('img').hover(function(){
   $(this).toggleClass('active'); // if hovered then it has class active
});
$(document).keypress(function(e) {    
    if(e.which == 100){
       $('.active').remove(); // if d is pressed then remove active image
    }
});
