deploy contract with quarkchain-web3.js in browser without metamask #10

I tried out the code (there is a typo which I fixed) in my browser and it seems to work fine: I can see the |

Thanks so much for your reply. I'm sorry for the typo made when I write the issue...However, I can deploy the contract but I still can't get the contract address for the second callback never happened. I change the workflow. Use the func code as follows: var tokenContractReturned = TokenContract.new(parseInt(req.body.totalSupply), req.body.tokenName, req.body.symbol, parseInt(req.body.decimals), req.body.ownerAddress, parseInt(req.body.buyRate), Date.parse(req.body.endDate),
{
data: bytecode,
gasPrice: 1000000000,
gas: 1000000,
fromFullShardId: finalFullShardId,
},function(err, tokenContract){
if(!err) {
//fromFullShardId: getTargetFullShardId(req.app.get('shard'))},
// NOTE: The callback will fire twice!
// Once the contract has the transactionId property set and once its deployed on an address.
// e.g. check tx hash on the first call (transaction send)
if(!tokenContract.address) {
console.log("/////////////////////txid////////////////////");
console.log(tokenContract.transactionId); // The id of the transaction, which deploys the contract
var transactionId = tokenContract.transactionId;
var transactionReceipt;
var intervId = setInterval(function(){
transactionReceipt = web3.qkc.getTransactionReceipt(transactionId);
if(!transactionReceipt) {
console.log(Date.now());
}
else {
clearInterval(intervId);
console.log(transactionReceipt);
req.app.set('shard', (req.app.get('shard')+1)%32);
res.json({address: `${transactionReceipt.contractAddress}${finalFullShardId.slice(2)}`});
}
}, 2000);
// check address on the second call (contract deployed)
} else {
console.log("/////////////////////address/////////////////");
console.log(tokenContract.address); // the contract address
}
// Note that the returned "myContractReturned" === "myContract",
// so the returned "myContractReturned" object will also get the address set.
}

oh, the fact that using a interval works probably means the server won't have the contract address ready until some time has passed :-) |
I forked qcgg/quarkchain-web3-contract-example.js and used it in browser. With MetaMask it woked fine. However, for supporting more browsers and more friendly to noob, I need use it without MetaMask. If I don't have a server, what should I do?
Here is my code.
I run the code in Safari and Chrome. All had the error as follows:
I would appreciate any suggestion!
Above all, when I used the sample code in server, I can only get the transactionId and no second callback for address but I can see the success of the deploy in testnet explorer, I need the contract address when I deploy it and tell the customers.
You can see I only get the txid back and then timeout. It's exactly same code besides I used require instead of import.
