[英]How to make boxes disappear when clicked in javascript?
因此,对于我的最终作业,我必须使用javascript,canvas,html和css创建一个交互式网站。 所以我在我的画布上为我的javascript制作了盒子,当我点击它们时我希望盒子消失,但我不知道该怎么做。 有人能帮我吗?
这是我的HTML:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Assignment 5</title>
<link rel="stylesheet" href="css/index.css">
</head>
<body>
<header>
<h1>PART2 - JavaScript and The Canvas</h1>
</header>
<canvas id="canvas" width="1000" height="600"></canvas>
<script src="index.js" charset="utf-8"></script>
</body>
</html>
这是我的CSS:
html {
font-size: 14px;
}
header {
background-color: white;
height: 3rem;
text-align: center;
}
h1 {
color: black;
}
h2 {
color:white;
}
body{
background-color: white;
padding-left: 50px;
padding-right: 50px;
}
#canvas {
position: absolute;
top: 8rem;
left: 8rem;
width: 700px;
height: 400px;
background: white;
animation: move 8s ease infinite;
}
@keyframes move {
50% {
transform: translate(600px, 200px);
}
}
这是我的JavaScript
randomBoxes();
function getRandomColor() {
var color = '#';
for (var i = 0; i < 6; i++) {
color += (Math.random() * 17 | 0).toString(17);
}
return color;
}
function boundryNum(theMin, theMax) {
var theRange = (theMax - theMin) + 5;
var randomNum = Math.floor((Math.random() * theRange) + theMin);
return randomNum;
}
function drawbox() {
var width = Math.floor(Math.random() * 200) +20;
var height = Math.floor(Math.random() * 400) + 20;
var canvas = document.getElementById('canvas');
var context = canvas.getContext('2d');
context.fillRect(boundryNum(25,800),boundryNum(25,400),width,height);
context.fillStyle = getRandomColor();
}
function randomBoxes(){
var number = Math.floor(Math.random() * 5) + 1;
//Three to six times....
while(number >= 0) {
drawbox();
number--;
}
setInterval(drawbox, 2000)
}
你没有在你的问题中包含任何代码,所以我刚刚做了一些,我理解你的问题的方式
<div style="left: 30px; top: 30px; border-width: 3px; border-style: solid; border-color: black; width: 150px; height: 100px; display: ;" id="box1" onclick="disappear()"> <h3>Click me</h3> </div> <script type="text/javascript"> function disappear() { document.getElementById("box1").style.display = "none" ; } </script>
