当点击“上传文件”按钮时，每个按钮加载自己的文件。现在，无论按下哪个按钮，所有内容都会应用于第一个按钮。谢谢

const inputFiles = document.querySelectorAll('.input-file');
if (inputFiles) {

    inputFiles.forEach(inputFile => {

            inputFileName.textContent = this.files[0].name.match(pattern)[1]
            inputFileName.classList.add("_active")

复制复制别人的代码时，检查是否有相同的name和id。

const inputFiles = document.querySelectorAll('[type="file"]');
if (inputFiles) {
  let pattern = /((?:.(?!\(\d+\)))+.)(?:\(\d+\))?\..+/;

  inputFiles.forEach(inputFile => {
    let parent = inputFile.closest('.left-form-calculator__files');
    let inputFileClose = parent.querySelector('.input-file-close');
    let inputFileName = parent.querySelector('.input-file-name');
    inputFile.addEventListener('change', function() {
      inputFileName.textContent = this.files[0].name.match(pattern)[1]
      inputFileName.classList.add('_active')
      inputFileClose.classList.add('_active')
    });
    inputFileClose.addEventListener('click', function() {
      inputFileName.classList.remove('_active')
      inputFileClose.classList.remove('_active')
