javascript - Image Slider that opens images from different folders on different button click -


i have image slider opens different images same folder(named images 1.jpg,2.jpg in folder img1). possible if can have buttons below image slider gives me sliding images different folders(1.jpg,2.jpg folder img2 ; 1.jpg,2.jpg folder img3)

<div id="slider">     <img src="img/1.jpg" alt="slide 1" />     <img data-src="img/2.jpg" alt="slide 2" />     <img data-src="img/3.jpg" alt="slide 3" />     <img data-src="img/4.jpg" alt="slide 4" /> </div><button>images new folder</button>

i'm guessing using library/code displays image in data-src. can change 'data-src' (or images' src) attribute dynamically , change path using.

it depends on implementation since lib might cache data-src on initialization , ignore changes it..

anyway, how can (i'm using src in example can change data-src well):

var gallery = document.queryselector('#gallery');  var button = document.queryselector('#your-button-id');    button.addeventlistener('click', () => setimagesfolder('foldername'));    function setimagesfolder(folder) {    gallery.queryselectorall('img').foreach(imgel => {      var currpath = imgel.getattribute('data-src');      var basepath = currpath.slice(currpath.lastindexof('/'))      console.log(folder + basepath)      imgel.setattribute('src', folder + basepath)    })  }
<div id="gallery">    <img data-src="folder/1.jpg">    <img data-src="folder/2.jpg">    <img data-src="folder/3.jpg">    <img data-src="folder/4.jpg">    <img data-src="folder/5.jpg">  </div>  <button id="your-button-id">change images path</button>
