如何使用前端部署智能合约.就像REMIX IDE正在做的那样

Question

我只想知道，是否有任何方法或机制可以像REMIX IDE那样一键部署合约。我只想部署具有不同参数的新合同。我不想使用truffle或REMIX来部署我的合同，我只想要我自己的部署方法。如果可能的话，请告诉我。我只想知道其他人是如何为每个新参数部署合约实例的。注意参数表示构造函数中的值。提前感谢

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);
});
