如何创建默认状态/清除容器并使用 HTML/CSS/JS 替换为新项目

Question

Hello I want to do something very specific and I have scoured stackoverflow but I cant figure out or find it.你好，我想做一些非常具体的事情，我已经搜索了 stackoverflow，但我无法弄清楚或找到它。 As seen in the below I want to replace the current container content with the new content user asked for but it appends below the current one(which I dont want) and I have tried remove(), removechild() nothing helps.如下图所示，我想用用户要求的新内容替换当前容器内容，但它附加在当前内容（我不想要）下面，我已经尝试过 remove()、removechild() 没有任何帮助。 Also after each pressing button for each property I want the triangle to return to its default state(without animations).此外，在每个属性的每个按下按钮之后，我希望三角形返回到其默认状态（没有动画）。 So is there a temporary way to add classes or animations using javascript. This is Expected when I click create and This is what I am getting.那么是否有使用 javascript 添加类或动画的临时方法。当我单击创建时这是预期的，这就是我得到的。
Here is the code:这是代码：

It looks like you're not clearing the container.看起来你没有清理容器。

Inside createHexs you could do this:在 createHexs 中你可以这样做：

    ...
    document.getElementById("createhexagons").innerHTML = "Pascal Triangle with 5(n) rows is created";
    container.innerHTML = '';
    for (let i = 0; i < hexagonPattern.length; i++) {
    ...

I'm not quite sure what you are trying to achieve with the property buttons, but this fixes the double rendering issue.我不太确定你想用属性按钮实现什么，但这解决了双重渲染问题。
