i want my popup (when a button is clicked) to show a random image out of my folder each time i click the button. I used html, css and javascript for my website.
The problem: it is the same random image each time. Only if i restart the page a different random image is showed.
What works right now: when i click the start-button a popup with a random image from that folder shows up (just how i want it) but if i click the close-button on my random picture and press the start-button again the same picture pops up again. Only if i restart my page then a new random picture will show when i press the start-button. But that picture stays the same, when i close the popup and want to start it again.
I want a random image everytime when i press the start-button without having to restart the page.
Do i use a boolean in javascript? Can i restart the function on its own? I have seen similar questions all the time but none of the solutions have worked for me kinda.
(the start-button is also a picture but it is a button) Sorry if the code is weirdly formatted, i am new to code <3
Thank you!!
My code:
HTML:
<div class="popup" id="popup-1">
<div class="overlay"> </div>
<div class="content">
<img class="imagelook"/> <!-- image is start-button -->
<div
class="close-btn"
onclick="togglePopup()"
onclick="generateRandomPicture(array)">× <!-- random image from folder -->
</div>
</div>
</div>
<body>
<button type="button" onclick="togglePopup()" class="imglook"></button> <!-- the start-button -->
</body>
Javascript:
function togglePopup(){
document.getElementById("popup-1").classList.toggle("active");
}
const imageArray =[
"zettel/9.png",
"zettel/8.png",
"zettel/10.png",
"zettel/11.png",
"zettel/12.png",
"zettel/13.png"
];
const image = document.querySelector("img");
window.onload = () => generateRandomPicture(imageArray);
function generateRandomPicture(array){
let randomNum = Math.floor(Math.random() * imageArray.length);
image.setAttribute("src", imageArray[randomNum]);
}
Perhaps the following might help - coded to allow for multiple popup elements in conjunction with multiple button elements to trigger the display of different images in the respective popup div
const images = [
"zettel/9.png",
"zettel/8.png",
"zettel/10.png",
"zettel/11.png",
"zettel/12.png",
"zettel/13.png"
];
const _CN='active';
const bttnclickhandler=function(e){
// generate random image based upon array
let imgsrc=images[mt_rand(0,images.length-1)];
// assign image the new src
this.previousElementSibling.querySelector('img').src=imgsrc;
this.previousElementSibling.classList.add(_CN);
console.info(imgsrc)
};
const closeclickhandler=function(e){
e.target.closest('.popup').classList.remove(_CN);
this.previousElementSibling.src='';
console.clear();
};
// generate a random number between a & b
const mt_rand=(a,b)=>Math.floor( Math.random() * ( b - a + 1 ) + a );
// assign listeners to all pertinent elements
document.querySelectorAll('button.imglook').forEach(n=>n.addEventListener('click',bttnclickhandler));
document.querySelectorAll('div.close-btn').forEach(n=>n.addEventListener('click',closeclickhandler));
document.querySelectorAll('div.popup').forEach(n=>{
n.querySelector('img').src=images[mt_rand(0,images.length-1)]
}).active{background:pink}
.popup{margin:1rem;}
.imglook{padding:1rem}<div class="popup">
<div class="overlay"></div>
<div class="content">
