I have a question about how the front end connects to the smart contract and how to call the function method of the smart contract? Is there a demo?

Hey! TON web wallet would be a good example of such application.

It uses a TonWeb, a library that has a lot of functionality to interact with the Blockchain and the contracts.

ye, I have used TonWeb.But I don't know if I connect successfully with the contract.

web3.js can call the contract method through the methods attribute, but I found through the source code that TonWen created a Contract object, and the methods attribute returned an empty object. So how should I call the function method of the smart contract?

I would suggest you to look at the contract implementations shipped with the TonWeb. There are a lot of examples. You will need to implement the Contract yourself and add the required methods to it.

Use the existing classes as a reference.

this?

So I can't directly call the methods of the contract like web3.js, and can only add the required methods through extend?

It's for Ethereum

What's the difference? 😄

hi,How should I call the smart contract method? Is there a hello world Demo?

The idea is to extend the Contract class and to implement the specific behavior of your contract, yes.

sorry。 Do you have a Demo on Github? Or simple ways to invoke smart contracts like Hello World are demo. I don't know exactly how to operate, thank you😂🙏

We don't have such contrived examples, but the repository contains implementation for various smart contracts. You should look at them and use them as a reference.

There is a TypeScript version of the codebase, which could be easier to read.

Yes, I looked at that wallet, but it doesn't feel like what I want.

Yes, I have read the code. But according to the source code, the methods property is an empty object.

If you just need to invoke a contract get-method then you need to call this:

Consider the Contract as an abstract class. It must be implemented properly, before it can be used. You will need to define your own methods in your sub-class.

Look at this for example:
https://github.com/slavafomin/tonweb/blob/typescripted/src/contract/token/nft/nft-collection.ts#L111

It's very uncommon for TON services to use TXID as transfer identification.

There’s an example of how to call methods in the post deploy test (in build/main.deploy.ts)

starat? 😅
