var key_code = 65;
，结果应为
character = "Esc";
我想转换键盘上的所有键。 我的演示在这里：
window.onload = function ()
{
var oP = document.getElementsByTagName("p")[0];
document.onkeydown = function (event)
{
var event = event || window.event;
oP.innerHTML = String.fromCharCode(event.keyCode);
return false
}
}<p></p>

你必须创建一个对象来存储它们并搜索你想要的对象。
你需要一个像
这样的集合myListN.B。您不能在json中使用数字键，只能使用字符串。
这将允许您使用密钥的文本名称搜索密钥代码。
如果您想要从密钥代码中搜索密钥，您可以使用如下数组：
var keys = {
"8" : "backspace",
"9" : "tab"
};
keys["8"];//etc

//这里是我的最终答案......希望得到任何好的建议，
window.onload = function () {
var showCode = document.getElementsByTagName('p')[0];
var keyMap = {
