jquery input doesnt accept numbers when set to case insensitive

Issue

i have this code

$("#search").keyup(function() {
    var val = $.trim(this.value);
    if (val === "")
        $('img').show();
    else {
        $('img').hide();
        $("img[alt*=" + val + "]").show();
    }
});

that makes you search trought images without any problem,
as this, it works case sensitive and i dont want that;
to make it case insensitive i’d have to add an i here
$("img[alt*=" + val + " i]").show(); before the ].

now it is case insensitive but the problem is that when i write numbers in the search bar it doesnt show anything but without the i it works

test here https://codepen.io/jvstalf/pen/LYQXoVy

document.addEventListener('mouseup', function(e) {
    var container = document.getElementById('bigImage');
    if (!container.contains(e.target)) {
      document.getElementById("overlay").style.display = "none";
      document.getElementById("bigImage").style.display = "none";
    }
  });

/* var mq = window.matchMedia( "(max-width: 1080px)" );
if (mq.matches) {
  function showThumbnail(){
    console.log('error')
  }
} 

function showThumbnail(clicked_id) {
  document.getElementById("overlay").style.display = "inherit";
  document.getElementById("bigImage").style.display = "inherit";
  document.getElementById("bigImage").src = document.getElementById(clicked_id).src;
}; */
var mq = window.matchMedia( "(max-width: 1080px)" );

function showThumbnail(clicked_id) {
  if (mq.matches) {
    console.log('error')
  } else {
    document.getElementById("overlay").style.display = "inherit";
  document.getElementById("bigImage").style.display = "inherit";
  document.getElementById("bigImage").src = document.getElementById(clicked_id).src;
  }
}

Solution

When you use the [attr*=value i] selector, you’ll need to wrap the value in single quotes, otherwise the browser will not consider it a valid selector when you use a number value.

Therefore it should look like [attr*='value' i].

So change

$("img[alt*=" + val + " i]").show();

to

$("img[alt*='" + val + "' i]").show();
