Atitit.js的键盘按键事件捆绑and事件调度

  

[js按键事件,and事件调度]Atitit.js的键盘按键事件捆绑and事件调度

  

1. Best的方法还是  
  
  

  
  
  objEvtMap[ id+evt ]=function(evt,element)
  
  

2. Event bind  
  

  
  
  function bindEvent_4_dataBlock()  {  var arr=$("#table1 li");  arr.each(function(index, element) {  $(element).keypress(function(){  alert('keypress');  });  var+index;  $(element).attr("id","data_aid_"+index);  objEvtMap[ id ]=function(evt,element)  {  if(evt=="down")  key_press_hadler($(element));  if(evt=="up")  key_press_hadler4up($(element));  if(evt=="left")  {};  if(evt=="rit")  {}  };  });  }
  
  

3. Event dispatch  
  
  

  
  
  document.onkeydown=function(event){  var e = event || window.event || arguments.callee.caller.arguments[0];  alert("keycode:"+e.keyCode);  if(e && e.keyCode==40 ){//下  //alert('40=下键,39=右键');  var now=$(".selected");  var id=$(now).attr("id");  var func=objEvtMap[id ];  func("down",now);  //key_press_hadler(now);  return false;  }
  
  

js中获取键盘事件  

  
  
  document.onkeydown=function(event){  var e = event || window.event || arguments.callee.caller.arguments[];  if(e && e.keyCode==){ // 按 Esc  //要做的事情  }  if(e && e.keyCode==){ // 按 F  //要做的事情  }  if(e && e.keyCode==){ // enter 键  //要做的事情  }  };  
  
  

只要你定义了这些键的动作,你在浏览器里按下这些键就会响应,兼容目前所有浏览器。

  

  

js 里面的键盘事件经常用到,所以收集了键盘事件对应的键码来分享下:  
  

  
  
  keyCode = BackSpace BackSpace  keyCode = Tab Tab  keyCode = Clear  keyCode = Enter  keyCode = Shift_L  keyCode = Control_L  keyCode = Alt_L  keyCode = Pause  keyCode = Caps_Lock  keyCode = Escape Escape  keyCode = space  keyCode = Prior  keyCode = Next  keyCode = End  keyCode = Home  keyCode = Left  keyCode = Up  keyCode = Right  keyCode = Down  keyCode = Select  keyCode = Print  keyCode = Execute  keyCode = Insert  keyCode = Delete  keyCode = Help  keyCode = equal braceright  keyCode = exclam onesuperior  keyCode = quotedbl twosuperior  keyCode = section threesuperior  keyCode = dollar  keyCode = percent  keyCode = ampersand  keyCode = slash braceleft  keyCode = parenleft bracketleft  keyCode = parenright bracketright  keyCode = a A  keyCode = b B  keyCode = c C  keyCode = d D  keyCode = e E EuroSign  keyCode = f F  keyCode = g G  keyCode = h H  keyCode = i I  keyCode = j J  keyCode = k K  keyCode = l L  keyCode = m M mu  keyCode = n N  keyCode = o O  keyCode = p P  keyCode = q Q at  keyCode = r R  keyCode = s S  keyCode = t T  keyCode = u U  keyCode = v V  keyCode = w W  keyCode = x X  keyCode = y Y  keyCode = z Z  keyCode = KP_ KP_  keyCode = KP_ KP_  keyCode = KP_ KP_  keyCode = KP_ KP_  keyCode = KP_ KP_  keyCode = KP_ KP_  keyCode = KP_ KP_  keyCode = KP_ KP_  keyCode = KP_ KP_  keyCode = KP_ KP_  keyCode = KP_Multiply KP_Multiply  keyCode = KP_Add KP_Add  keyCode = KP_Separator KP_Separator  keyCode = KP_Subtract KP_Subtract  keyCode = KP_Decimal KP_Decimal  keyCode = KP_Divide KP_Divide  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = F  keyCode = Num_Lock  keyCode = Scroll_Lock  keyCode = acute grave  keyCode = comma semicolon  keyCode = minus underscore  keyCode = period colon  keyCode = numbersign apostrophe 万彩娱乐注册 keyCode = plusminus hyphen macron  keyCode =  keyCode = copyright registered  keyCode = guillemotleft guillemotright  keyCode = masculine ordfeminine  keyCode = ae AE  keyCode = cent yen  keyCode = questiondown exclamdown  keyCode = onequarter onehalf threequarters  keyCode = less greater bar  keyCode = plus asterisk asciitilde  keyCode = multiply division  keyCode = acircumflex Acircumflex  keyCode = ecircumflex Ecircumflex  keyCode = icircumflex Icircumflex  keyCode = ocircumflex Ocircumflex  keyCode = ucircumflex Ucircumflex  keyCode = ntilde Ntilde  keyCode = yacute Yacute  keyCode = oslash Ooblique  keyCode = aring Aring  keyCode = ccedilla Ccedilla  keyCode = thorn THORN  keyCode = eth ETH  keyCode = diaeresis cedilla currency  keyCode = agrave Agrave atilde Atilde  keyCode = egrave Egrave  keyCode = igrave Igrave  keyCode = ograve Ograve otilde Otilde  keyCode = ugrave Ugrave  keyCode = adiaeresis Adiaeresis  keyCode = ediaeresis Ediaeresis  keyCode = idiaeresis Idiaeresis  keyCode = odiaeresis Odiaeresis  keyCode = udiaeresis Udiaeresis  keyCode = ssharp question backslash  keyCode = asciicircum degree  keyCode = sterling  keyCode = Mode_switch
  
  

使用event对象的keyCode属性判断输入的键值  
  

  

eg:if(event.keyCode==)alert(“enter!”);  

  

键值对应表  

  
  
  A  X  U   X  B  X  V   X  C  X  W   X  D  X  X   X  E  X  Y   X  F  X  Z   X  G  X     X  H  X     X  I  X     X  J  X    X  K  X    X  L  X    X  M  X     X  N  X     X  O  X     X  P  X     X  Q  X ESC  XB  R  X CTRL  X  S  X SHIFT X  T  X ENTER XD
  
  

如果要使用组合键,则可以判断是否同时按下了这几个键,比如ctrl键、shift键以及alt键的组合使用就可以判断是否多按下了ctrl键、shift键以及alt键
