Question

所以我试图能够输入整数，将它们推入一个数组，然后显示该数组。但是我无法显示它。我不知道如何显示一个小格式的段落。我需要隐藏段落，然后在我按下按钮时显示它或创建它并用文本填充它。谢谢

<input type="text" name="hello" id="f">
<button onclick="push()" class= "push">push</button>
<button onclick="displaybut()" class="displaybut">display</button>


    
</body>
<script src="script.js"></script>
</html>

let button = document.querySelector(".push");
let inp = document.querySelector("input");
var arr = [];

function push(){
    if (inp.value != ""){
        arr.push(inp.value);
        inp.value = ''
    }
    console.log(arr);
}

let para = document.createElement("p");
function displaybut(){
    para.innerHTML = "This is the final array"+ arr ;
    
}

使用js显示格式化的段落
