Question

我是 Javascript 初学者，我需要一些帮助。所以，我需要，当我按下按钮时，出现“左侧”段落

<div id="content">
        <script>
            function myFunction() {
                document.getElementById("contentp").innerHTML = leftside;
                var x = document.getElementById("leftside")
                x.style.display = "normal";
            }


        </script>
        <button id="buttonI" type="button" onclick="myFunction()">Show left side!</button>

        <p id="leftside" style="display: none">Left side</p>

        <p id="contentp"></p>

Answer 1

x.style.display = "block";

将其设置为block或display的其他值，除了none
