如何将ETH值发送到在ethers.js中应支付的特定智能合约功能？

const ethers = require('ethers');

const privateKey = '0xYourPrivateKey'; // 替换为你的私钥
const wallet = new ethers.Wallet(privateKey);

const provider = ethers.getDefaultProvider('ropsten'); // 替换为你想要连接的以太坊网络

const contractAddress = '0xYourContractAddress'; // 替换为你的智能合约地址
const contractABI = [...]; // 替换为你的智能合约ABI
const contract = new ethers.Contract(contractAddress, contractABI, wallet);

const valueToSend = ethers.utils.parseEther('1'); // 替换为你想要发送的ETH值
const transaction = await contract.payFunction({ value: valueToSend });
await transaction.wait(); // 等待交易确认
