用wagmi usePrepareContractWrite填充写args

Question

我正在使用wagmi usePrepareContractWrite和write为我的合同写信。我允许用户上传字段并创建一个NFT。有办法在写函数中设置args吗？例如，我有

  const { config, status } = usePrepareContractWrite({
    addressOrName: "0xADDRESS",
    contractInterface:  "abi file",
    functionName: "safeMint",
  });
  const { data, isLoading, isSuccess, write } = useContractWrite(config);


  write();

如果我将args:["address", "NFT data"]添加到usePrepareContractWrite中，效果会很好。但是，是否有一种方法可以在write()中设置这一点呢？因为NFT信息仅在用户上传、图像和字段之后才可用。

你可以用useState来做这样的事情，只是把代码放在一起并不能测试.

import React, { useState } from 'react';

function Example() {
  // Declare a new state variable, which we'll call "param"
  const [param, setParam] = useState("");

  const { config, status } = usePrepareContractWrite({
    addressOrName: "0xADDRESS",
    contractInterface:  "abi file",
    functionName: "safeMint",
    args: [param]
  });
  const { data, isLoading, isSuccess, write } = useContractWrite(config);

  return (
    <div>
      <form>
       <input
          type="text"
          placeholder="parameter type here"
          name="param"
          onChange={(e) => setParam(e.target.value)}
        />
        <button onClick={() => write()}>
          Click me
        </button>
      </form>
    </div>
  );
}
