JavaScript display and hide pictures for your reference. The specific contents are as follows

Click the button to display and hide the picture (displayed by default), and attach the code:

    < button > Hide < / button >
    <img src="img/image01.jfif">
    <script type="text/javascript">
        // 1. Get event source
        var obtn = document.getElementById("btn");
        var newImg = document.getElementsByTagName("img")[0];
        // var isShow = true; // Method 2

        // 2. Binding event
        obtn.onclick = function (){
            //If (isshow) {// method 2
            If (obtn. InnerHTML = = 'hidden'){
                // 3. Event driver
       = 'none';
                obtn. InnerHTML = "display"//
                // isShow = false; // Method 2
            }else {
       = 'block';
                obtn. InnerHTML = "hidden";
