Using jQuery to change image src when browser is resized

Question

I have two different sized images, one if for screens smaller than 759px, the other is for screens larger than 759px.

I have managed to get the source of the images

Answer 1

First try this...

change your follwoing line of code

$(window).bind("resize", function(){//Adjusts image when browser resized
        imageresize();
    });

to

// Bind event listener
    $(window).resize(imageresize);

and put alert inside imageresize to see if it works or not...

In case above do not work out...I believe there is one problem probably..

in your code you have

$(document).ready(function() {

 $(window).bind("resize", function(){//Adjusts image when browser resized
        imageresize();
    });
}

So the function for reside inside jquery which may not work well. On top of that try using simple javascript; i had similar problem and solved using plain javascript and jquery did not work in some browsers.

Sound strange enough to stop you try at it but would work...

It's not jQuery but you can simple use document.getElementById("myId").src="another.jpg"; to define the new src of the img with id "myId".

Try to use css3 media queries instead of doing it in jQuery or javascript.

Consider using "img-src" class on a . Whenever the screen is resized b/w 600px to 900px; x2.jpg will be loaded. By default x1.jpg will be used.

Ex:

.img-src {
   background-image: url("http://imageurlhere.com/x1.jpg");
}


@media (min-device-width:600px) and (max-width:900px) {
  .img-src {
      background-image: url("http://imageurlhere.com/x2.jpg");
   }
}

Your code works fine, as I can see, but I prefer to use setTimeout, some times page could slow down without resize pause.

$(document).ready(function() {
    var resizeTimer,
        $window = $(window);

    function imageresize()
    {
        if ($window.width() < 700)
        {
            $('.fluidimage').text('< 700');
        }
        else
        {
            $('.fluidimage').text('>= 700');
        }
    }
    imageresize();//Triggers when document first loads

    $window.resize(function() {
        clearTimeout(resizeTimer);
        resizeTimer = setTimeout(imageresize, 100);
    });
 });
