键盘精灵
键盘精灵是一种便捷操作软件的功能工具，通过按键实现快速功能操作。
目前内置1.0版本只支持切换股票， 后续会增加快捷键，切换指标等功能

步骤
1. 创建键盘精灵实例
var hqKeyboard=new JSPopKeyboard();
2. 设置事件回调
设置键盘精灵选中事件
hqKeyboard.Keyboard.Option.EventCallback=
[{event:JSCHART_EVENT_ID.ON_KEYBOARD_SELECTED, //切换股票callback:(event, data, obj)=>{ console.log("[JSCHART_EVENT_ID.ON_KEYBOARD_SELECTED] data", data)hqKeyboard.Hide();if (data && data.Data && data.Data.Symbol){klineControl.Chart.Focus();klineControl.ChangeSymbol(data.Data.Symbol);} }},
]
3. 初始化键盘精灵
hqKeyboard.Inital();
hqKeyboard.Create();
4. 设置码表数据
....
//TODO 请求码表数据
hqKeyboard.SetSymbolData(data)
码表格式
[{ Symbol:完整的股票代码（带后缀的），Name:股票名称，ShortSymbol:股票代码（不后缀的）,Spell:拼音缩写TypeName:类型名称，可以自己取如“股票“，”指数“Color:单行文字颜色（可选）},]
5. 监听"keydown",“mousedown”
“keydown” 用来处理键盘输入
“mousedown” 用来处理点击其他区域隐藏键盘精灵
document.addEventListener('keydown', (event) =>
{var div=document.getElementById('kline'); if (div.contains(event.target)) //在K线上才出来键盘精灵{hqKeyboard.OnGlobalKeydown(event) }
});document.addEventListener("mousedown", (event)=>{ hqKeyboard.OnGlobalMouseDown(event) })
