<cc-defineKeyboard ref="CodeKeyboard" passwrdType="pay" @KeyInfo="KeyInfo"></cc-defineKeyboard>

/** * 唤起键盘 */

},

/*** 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);

}
