1. La meilleure méthode reste
objEvtMap[ id+evt ]=function(evt,element)
2. Liaison d'événement
function bindEvent_4_dataBlock() { var arr=$("#table1 li"); arr.each(function(index, element) { $(element).keypress(function(){ alert('keypress'); }); var id="data_aid_"+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($(element)); if(evt=="left") {}; if(evt=="rit") {} }; }); }
3. Envoi d'un événement
document.onkeydown=function(event){ var e = event || window.event || arguments.callee.caller.arguments[0]; alert("keycode:"+e.keyCode); if(e && e.keyCode==40 ){//下 //alert('40=下键,39=右键'); var now=$(".selected"); var id=$(now).attr("id"); var func=objEvtMap[id ]; func("down",now); //key_press_hadler(now); return false; }
Obtenir les événements du clavier en js
<script type="text/javascript" language=JavaScript charset="UTF-"> 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 } }; </script>
Tant que vous définissez les actions de ces touches, elles répondront lorsque vous appuierez sur ces touches dans le navigateur. Il est compatible avec tous les navigateurs actuels.
Les événements clavier en js sont souvent utilisés, j'ai donc collecté les codes touches correspondant aux événements clavier à partager :
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 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
Utilisez l'attribut keyCode de l'objet événement pour déterminer la valeur de la clé d'entrée
par exemple : if(event.keyCode==)alert("enter!");

Si vous souhaitez utiliser des combinaisons de touches, vous pouvez déterminer si ces touches sont enfoncées en même temps. Par exemple, la combinaison de la touche ctrl, de la touche maj et de la touche alt peut déterminer si la touche ctrl, la touche maj, et la touche alt sont enfoncées plusieurs fois
