按键测试，支持像 Ctrl+Alt+Shift+T 的组合键_javascript技巧

按键测试，支持像 Ctrl+Alt+Shift+T 的组合键（注：非浏览器热键） <script type="text/javascript"> function showKeyName(e) { var keyName; switch(e.keyCode) { case 8:keyName = "[退格]";break; case 9:keyName = "[Tab]";break; case 13:keyName = "[Enter]";break; case 16:keyName = "[Shift]";break; case 17:keyName = "[Ctrl]";break; case 18:keyName = "[Alt]";break; case 19:keyName = "[PauseBreak]";break; case 20:keyName = "[Caps Lock]";break; case 27:keyName = "[Esc]";break; case 32:keyName = "[空格]";break; case 33:keyName = "[PageUp]";break; case 34:keyName = "[PageDown]";break; case 35:keyName = "[End]";break; case 36:keyName = "[Home]";break; case 37:keyName = "[方向键左]";break; case 38:keyName = "[方向键上]";break; case 39:keyName = "[方向键右]";break; case 40:keyName = "[方向键下]";break; case 45:keyName = "[Insert]";break; case 46:keyName = "[Delete]";break; case 91:keyName = "[左Win]";break; case 92:keyName = "[右Win]";break; case 93:keyName = "[快捷菜单键]";break; case 95:keyName = "[Sleep]";break; case 96:keyName = "[小键盘区0]";break; case 97:keyName = "[小键盘区1]";break; case 98:keyName = "[小键盘区2]";break; case 99:keyName = "[小键盘区3]";break; case 100:keyName = "[小键盘区4]";break; case 101:keyName = "[小键盘区5]";break; case 102:keyName = "[小键盘区6]";break; case 103:keyName = "[小键盘区7]";break; case 104:keyName = "[小键盘区8]";break; case 105:keyName = "[小键盘区9]";break; case 106:keyName = "[*]";break; case 107:keyName = "[+]";break; case 109:keyName = "[-]";break; case 110:keyName = "[.]";break; case 111:keyName = "[/]";break; case 112:keyName = "[F1]";break; case 113:keyName = "[F2]";break; case 114:keyName = "[F3]";break; case 115:keyName = "[F4]";break; case 116:keyName = "[F5]";break; case 117:keyName = "[F6]";break; case 118:keyName = "[F7]";break; case 119:keyName = "[F8]";break; case 120:keyName = "[F9]";break; case 121:keyName = "[F10]";break; case 122:keyName = "[F11]";break; case 123:keyName = "[F12]";break; case 144:keyName = "[NumLock]";break; case 145:keyName = "[ScrollLock]";break; case 186:keyName = "[;]";break; case 187:keyName = "[=]";break; case 188:keyName = "[,]";break; case 189:keyName = "[-]";break; case 190:keyName = "[.]";break; case 191:keyName = "[/]";break; case 192:keyName = "[`]";break; case 219:keyName = "[[]";break; case 220:keyName = "[\\]";break; case 221:keyName = "[]]";break; case 222:keyName = "[']";break; //case 255:keyName = "[Power]";break; //奇怪，怎么[Power]键和[Wake]键键值是一样的？ case 255:keyName = "[Wake]";break; default:keyName = "[" + String.fromCharCode(e.keyCode) + "]";break; } if((e.shiftKey)&&(e.keyCode!=16)){keyName = "[Shift] + " + keyName;} if((e.altKey)&&(e.keyCode!=18)){keyName = "[Alt] + " + keyName;} if((e.ctrlKey)&&(e.keyCode!=17)){keyName = "[Ctrl] + " + keyName;} return keyName; } </script>
