events - 如何获取删除键的 event.keyCode？

Question

$('body').keypress(function(event){

     if(event.keyCode == 46){console.log('Delete Key Pressed')}; //does not work

     if(event.keyCode == 32){console.log('SPACE BAR')}; //works
})

Why doesn't the delete key show up in THIS FIDDLE ?

Answer 1

使用 keyup 或 keydown 事件代替 keypress:keypress 用于可打印字符，而 keydown 将捕获非打印按键，包括删除、退格和返回。

$('body').keydown(function(event){
    var letter = String.fromCharCode(event.which); 
    if(event.keyCode == 32){console.log('SPACE BAR');}
    if(event.keyCode == 46){console.log('Delete Key Pressed');}
    console.log(event); 
    console.log(event.keyCode); 
 });
