Как применить класс к разным блокам при клике?

const inputFiles = document.querySelectorAll('.input-file');
if (inputFiles) {
    const inputFileClose = document.querySelector('.input-file-close');
    const inputFileName = document.querySelector('.input-file-name');
    let pattern = /((?:.(?!\(\d+\)))+.)(?:\(\d+\))?\..+/
    inputFiles.forEach(inputFile => {
        inputFile.addEventListener("change", function (e) {
            inputFileName.textContent = this.files[0].name.match(pattern)[1]
            inputFileName.classList.add("_active")
            inputFileClose.classList.add("_active")
        });
        inputFileClose.addEventListener("click", function (e) {
            inputFileName.classList.remove("_active")
            inputFileClose.classList.remove("_active")
        });
    });
}
