哪里有做枪网站的怎么寻找网站关键词并优化

组件功能分析
1.按键删除，清空当前input，并跳转prevInput & 获取焦点,按键delete，清空当前input，并跳转nextInput & 获取焦点。按键Home/End键，焦点跳转first/最后一个input输入框。ArrowLeft/ArrowRight键点击后跳转上一个/下一个输入框获取焦点。
2.判断按键为数字，则取第一个数字，然后跳转下一个input输入框获取焦点，如果为最后一个，则失去焦点，交互结束。
3.粘贴功能。通过el.clipboardData获取粘贴内容，判断是否为4/6位粘贴内容。是则赋值给页面Input，双向绑定一个数组即可。否则置为空。
