blockchain - 如何使用前端部署智能合约。就像 REMIX IDE 正在做的那样

Question

我只是想知道是否有任何方法或机制可以像 REMIX IDE 一样通过单击来部署合约。我只想部署具有不同参数的新合同。我不想使用 truffle 或 REMIX 来部署我的合约，我只想要我自己的部署方法。如果可能的话请让我知道。我只想知道其他人如何为每个新参数部署合约实例。 注意参数意味着构造函数中的值。提前致谢

myContract.deploy({
    data: '0x12345...',
    arguments: [123, 'My String']
})
.send({
    from: '0x1234567890123456789012345678901234567891',
    gas: 1500000,
    gasPrice: '30000000000000'
}, function(error, transactionHash){ ... })
.on('error', function(error){ ... })
.on('transactionHash', function(transactionHash){ ... })
.on('receipt', function(receipt){
   console.log(receipt.contractAddress) // contains the new contract address
})
.on('confirmation', function(confirmationNumber, receipt){ ... })
.then(function(newContractInstance){
    console.log(newContractInstance.options.address) // instance with the new contract address
});


// When the data is already set as an option to the contract itself
myContract.options.data = '0x12345...';

myContract.deploy({
    arguments: [123, 'My String']
})
.send({
    from: '0x1234567890123456789012345678901234567891',
    gas: 1500000,
    gasPrice: '30000000000000'
})
.then(function(newContractInstance){
    console.log(newContractInstance.options.address) // instance with the new contract address
});


// Simply encoding
myContract.deploy({
    data: '0x12345...',
    arguments: [123, 'My String']
})
.encodeABI();
> '0x12345...0000012345678765432'


// Gas estimation
myContract.deploy({
    data: '0x12345...',
    arguments: [123, 'My String']
})
.estimateGas(function(err, gas){
    console.log(gas);
});
