我是一个绝对的noob与编码和必须编码一个网站为学校现在。 我试图创建一个显示图像的按钮，下面的代码是我现在得到的。 我现在想要的是创建另一个按钮，使图像再次关闭。 我已经谷歌周围但只能找到解释如何使一个按钮回到另一个页面的东西，但我只想它关闭图像，有人能帮助吗？
<html>
<head>
<title>click</title>
<style>
#image{
display:none;
}
</style>
</head>
<body>
<div>
<img src="imgpinnwand/flyer_NEU.png" width=800 height=400 id="image" alt="Flyer" />
</div>
<button type="button" onclick="imageShow()"><img src="imgpinnwand/Postit.png" width=400 height=400></button>
<script>
function imageShow(){
document.getElementById('image').style.display = "block";
}
</script>
</body>
</html>
您可以使用以下代码隐藏/关闭图像:
<div>
<img src="imgpinnwand/flyer_NEU.png" width=800 height=400 id="image" alt="Flyer" id="myP" />
</div>
<button type="button" onclick="myFunction()">Hide image</button>
<button type="button" onclick="myFunction2()">show image</button>
<script>
function myFunction() {
document.getElementById("myP").style.visibility = "hidden";
}
function myFunction2() {
document.getElementById("myP").style.visibility="visible";
}
</script>
我希望这就是你要找的。 这里是如何创建模型图像的完整指南。

// Get the modal
var modal = document.getElementById("myModal");
// Get the image and insert it inside the modal - use its "alt" text as a caption
var img = document.getElementById("myImg");

img.onclick = function(){

modalImg.src = this.src;
