<div class="myDiv">
 <img  src="img-1.jpg" data-tablet="img-2.jpg" data-mobil="img-3.jpg">

MY JS

$(document).ready(function(){

    $(window).resize(function(){
      var tabletSrc = $(".main-carousel img").attr("data-tablet");
      var mobilSrc = $(".main-carousel img").attr("data-mobil");
      if($(window).width() <=768){

         $('img').attr('src',tabletSrc);
      }
      if($(window).width() <=480 ) {
         $('img').attr('src',mobilSrc);
      }
  });

});

Question: how can I do what I want, if you click that you won’t see anything?

Note: I do not want to use srcset or css

Answer 1

You can try this for several carousel images.

function makeResize(){
  var imageSrc = $(".myDiv img");
  if($(window).width() <=768 && $(window).width()>480){
    $(imageSrc).each(function(key,value){
      $(value).attr('src',$(value).data('tablet'));
    });
  }else if($(window).width() <=480 ) {
    $(imageSrc).each(function(key,value){
      $(value).attr('src',$(value).data('mobile'));
    });
  }else{
    $(imageSrc).each(function(key,value){
      $(value).attr('src',$(value).data('default'));
    });
  }
}

$(document).ready(function(){
    $(window).resize(function(){
        makeResize();
    });
    makeResize();
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div class="myDiv">
 <img  src="org1.jpg" data-default="org1.jpg" data-tablet="tablet1.png" data-mobile="mobile1.jpg">
 <img  src="org2.jpg" data-default="org2.jpg" data-tablet="tablet2.png" data-mobile="mobile2.jpg">
 <img  src="org3.jpg" data-default="org3.jpg" data-tablet="tablet3.png" data-mobile="mobile3.jpg">
</div>

srcset js .

<img src="images/space-needle.jpg"
srcset="images/space-needle.jpg 200w, images/space-needle-2x.jpg 400w,
images/space-needle-hd.jpg 600w">

Answer 4

You are using the wrong one class name. Your div has a class of "myDiv" and you select "main-carousel"

$(document).ready(function(){

    $(window).resize(function(){
      var tabletSrc = $(".myDiv img").attr("data-tablet");
      var mobilSrc = $(".myDiv img").attr("data-mobil");
      if($(window).width() <=768){

         $('img').attr('src',tabletSrc);
      }
      if($(window).width() <=480 ) {
         $('img').attr('src',mobilSrc);
      }
  });

});

Keep a short width first. Your validation is always performed for tablet. as480 < 768

Change your conditions as follows.

$(window).resize(function(){
      var tabletSrc = $(".someDiv img").attr("data-tablet");
      var mobilSrc = $(".someDiv img").attr("data-mobil");
      var imgSrc = "defaultImageSrc" //src for default image
      var windowWidth = $(window).width();
      if(windowWidth <= 480 ) { //first small width
         imgSrc = mobilSrc;
      }else if(windowWidth <= 768){ //next larger one
         imgSrc = tabletSrc;
      } //if else default will there for you which is initialised there.
});

Answer 6

Try the following:

$(window).resize(function(){

var realImg =  $(".main-carousel img").attr();
var tabletSrc = $(".main-carousel img").data("tablet"); //use .data instead of attr
var mobilSrc = $(".main-carousel img").data("mobil");

  if($(this).width() <= 768){
     $('img').attr('src',tabletSrc);
  }
  else if($(this).width() <= 480 ) { // use else if instead of if
     $('img').attr('src',mobilSrc);
  }

  else{
   $('img').attr('src',realImg);
  }

});
