#### 使用方法
```使用方法
<!-- ref:唯一ref passwrdType：密码样式pay keyInfo：密码输入监测事件 -->
<cc-defineKeyboard ref="CodeKeyboard" passwrdType="pay" @KeyInfo="KeyInfo"></cc-defineKeyboard>
/** * 唤起键盘 */
onPayUp() {
this.$refs.CodeKeyboard.show();
},
/*** 支付键盘回调* @param {Object} val */
KeyInfo(val) {
if (val.index >= 6) {
return;
}
// 判断是否输入的是删除键
if (val.keyCode === 8) {
// 删除最后一位
this.passwordArr.splice(val.index + 1, 1)
}
// 判断是否输入的是.
else if (val.keyCode == 190) {
// 输入.无效
} else {
this.passwordArr.push(val.key);
}
uni.showModal({
title: '温馨提示',
content: '输入密码是 = ' + JSON.stringify(this.passwordArr)
})
}
```
