I am trying to make a game and I have been trying to get the character button to disappear and reappear on click. I think the if else statements is the best way to do it but I am probably wrong because I am new to javascript. I managed to make it disappear but couldn't make it appear again on click html:
<body>
<div id="game">
<div id="block"></div>
<button id="character" onclick="myFunction()"></button>
</div>
<script>
function myFunction() {
if (document.getElementById("character").style.display="block" == true) {
document.getElementById("character").style.display="none";
} else {
document.getElementById("character").style.display="block";
}
}
</script>
</body>
</html>
css:
*{
padding: 0;
margin: 0;
}
#game {
margin: auto;
width: 400px;
height: 500px;
border: 1px solid black;
overflow: hidden;
}
#block {
width: 50px;
height: 500px;
background-color: black;
position: relative;
left: 400px;
animation: block 2s infinite linear;
}
@keyframes block {
0%{left: 400px;}
100%{left: -50px;}
}
#character {
height: 50px;
width: 50px;
background-color: black;
margin: auto;
top: 250px;
margin-left: 15px;
position: absolute;
display: block;
}
let x = 0;
document.getElementsByTagName('body')[0].addEventListener('click',function(){
let char = document.getElementById('character')
if(x%2 == 0){
x++;
char.classList.remove('show')
char.classList.add('hide')
}else{
x++
char.classList.remove('hide')
char.classList.add('show')
}
}).hide{
display:none;
}
.show{
display:block;
}
*{
padding: 0;
margin: 0;
}
#game {
margin: auto;
width: 400px;
height: 500px;
border: 1px solid black;
overflow: hidden;
}
#block {
width: 50px;
height: 500px;
background-color: black;
position: relative;
left: 400px;
animation: block 2s infinite linear;
}
@keyframes block {
0%{left: 400px;}
100%{left: -50px;}
}
#character {
height: 50px;
width: 50px;
background-color: black;
margin: auto;
top: 250px;
margin-left: 15px;
position: absolute;
} <body>
<div id="game">
<div id="block"></div>
<button id="character" class='show'></button>
</div>
</body>Try this:
<body>
<div id="game">
<div id="block"></div>
<button id="character" onclick="myFunction()"></button>
</div>
<script>
function myFunction() {
if (document.getElementById("character").style.display==="block") {
document.getElementById("character").style.display="none";
} else {
document.getElementById("character").style.display="block";
}
}
</script>
</body>
</html>
What are you going to click in order to show the hidden box,since you have made it disappear ?
I created this snippet below to explain the logic you could follow in order to toggle between visible and hidden black boxes,you definitely need to click something to initiate visibility for the desired elements so i created a button for that.
function showElements(arr) accepts an array of id's you want to bring them back to page.
.black-box {
height: 50px;
width: 50px;
background-color: black;
position: relative;
display: block;
margin:5px;
float: left;
}<html>
<body>
<div id="game">
<div id="block"></div>
<button onclick="showElements(['character','character2'])">SHOW ELEMENTS</button>
<button class="black-box" id="character" onclick="hideThisElement(this)" style="display:block"></button>
<button class="black-box" id="character2" onclick="hideThisElement(this)" style="display:block"></button>
</div>
<script defer>
function hideThisElement(e){
e.style.display = "none";
}
function showElements(arr){
arr.forEach(el => {
let elId = document.getElementById(el)
if(document.body.contains(elId)){
if(elId.style.display == "none"){
elId.style.display = "block"
}
}
})
}
</script>
</body>
</html>
