How to get the transaction hash once it is mined?

Question

In JavaScript (web3.js), how do I get the transaction-hash corresponding to a function executed in my smart contract?

Answer 1

When you send a transaction to a contract function, you get back the transaction hash:

var txHash = myContract.myFunction(param1, { from: you });

If there is a transaction that you need to find, look into your sender address at etherscan.io.
