Javascript 隐藏和显示 id

Question

我不想要一个按钮，我想要一个倒计时 5 秒的计时器，然后 javascript function 在页面加载时执行

<!DOCTYPE html>
<head>
    <link rel="stylesheet" href="css/app.min.css" />
    <title>
        Test
    </title>
</head>
<body>
    <!-- I don't want a button I want a timer instead that counts down 5 seconds then the javascript function executes -->

    <button onclick="myFunction()">Click Me</button>

    <div id="myDIV", class="myDIV">
        Initializing Hide
      </div>

      <div id="myDIVS", class="myDIVS">
        Hide Successful
      </div>


    <script type="text/javascript">
        function myFunction(){
            var target = document.getElementById("myDIV");
            var show = document.getElementById("myDIVS");
            if(target.style.display = "none"){
                // target.style.display = "block";
                show.style.display = "block";
            }else{
                show.style.display = "block";
            }
        }

        
    </script>
</body>

<style>
    .myDIV{
        background-color: aqua;
        margin: 30px;
        padding: 50px 30px;
        /* display: none; */
    }

    .myDIVS{
        background-color: green;
        margin: 30px;
        padding: 50px 30px;
        display: none;
    }
</style>```

您需要使用setTimeout() 。 只需将onClick代码放入其中，我也纠正了= vs. ==错误。

 function myFunction() { var target = document.getElementById("myDIV"); var show = document.getElementById("myDIVS"); if (target.style.display == "none") { target.style.display = "block"; show.style.display = "none"; } else { target.style.display = "none"; show.style.display = "block"; } } setTimeout(myFunction, 5000);

 .myDIV { background-color: aqua; margin: 30px; padding: 50px 30px; /* display: none; */ }.myDIVS { background-color: green; margin: 30px; padding: 50px 30px; display: none; }

 <div id="myDIV" class="myDIV"> Initializing Hide </div> <div id="myDIVS" class="myDIVS"> Hide Successful </div> Wait for five seconds and see?
