我正在建立一个学校的时间表，现在得到了一个弹出窗口，你可以输入你的主题和它保存在一个变量.我怎么能让这个变量显示在其中一个按钮？这是我的HTML代码：

<input type="text" id="fach"/>
<input type="color" />
<button type="button" onclick="Fach()">OK</button>
</div>
</div>
</main>
</body>
</html>这是我的JS代码：
hamburger = document.querySelector(".hamburger");
hamburger.onclick = function()
{
navBar = document.querySelector(".nav-bar");
navBar.classList.toggle("active");
}
let popup = document.getElementById("popup");
function openPopup(){
popup.classList.add("open-popup");
}
function closePopup(){
popup.classList.remove("open-popup");
}
function Fach() {
var textInput = document.getElementById("fach").value;
}我还没有尝试太多，因为我是新的html和js，但我没有找到任何解决方案在线。我的目标是改变按钮显示从'+'的主题变量。
