问题 Is there any way to detect the shift key being pressed while the mouse is already over a particular element? Right now, what I have is this: $( "body" ).on("mouseover", ".topic:not(.loadable) > p", function ( event ){ if(event.shiftKey){ this.style.color = 'goldenrod'; } }); $( "body" ).on("mouseleave", ".topic:not(.loadable) > p", function ( event ){ this.style.color = 'black'; }); But it only changes color if the shift key was being held prior to entering the element. 来源： https:/
