Web3.js: web3js 1.0 web3.methods.mymethod.send({from:account}) needs to support sending ether

[simonmittag]

Hi,

we are trying to send ether to an endpoint in a solidity contract, marked up with payable, i.e:

function blah(uint256 param) payable { //impl here }

In a previous version of web3.js, <0.20, this worked like so:

contractInstance.blah(param, {from:account, value:wei});

in 1.0 beta18, we can't seem to find the 'value' argument in any headers. is this supported yet? If not, how can i transact, while calling a specific contract function? The new send function looks like this:

contractInstance.methods.mymethod(param).send({from:account});

Missing the value parameter?

If this is not the correct approach please advise, i.e. are we meant to use web3.eth.sendTransaction() directly?

Thank you in advance.

Simon

Hey @simonmittag! I was confused by this as well, but it looks like in the send function you can pass value as one of the options for sending ether to a payable method. Something like:

contractInstance.methods.mymethod(param).send({from:account, value:wei})

Perhaps we should look into adding it to the documentation since neither of us found it.

anyone? I had the same problem..

It will look like this now:

contractInstance.methods.mymethod(param).send({from: address, value: web3.utils.toWei( value, 'ether')})

getting undefined in every possible way, Is that deprecated apI? I cannot find it in the document.

This got fixed with the latest version of Web3.js.
