<img src="first.jpg" alt="first" width="500" height="600" />
<img src="second.jpg" alt width="500" height="600" />
<img src="third.jpg" alt="third" width="500" height="600" />
<img src="fourth.jpg" alt width="500" height="600" />
<img src="fifth.jpg" alt="" width="500" height="600" />

find image tags with alt attribute without double quotes and replace with empty double quotes for ADA accessibility, I need to jquery to find second and fourth img tags replace with alt="" just like fifth. This is sample html markup, a page can have this instances 10 or 20 instances, all these should be replaced with alt=""

I tried this below didn't work

$(function() {
  $("img").each(function() {
    if (this.alt) {
      console.log(this.alt);
    } else {
      $(this).attr('alt', "");
    }
  });
});

I am working on .NET MVC project and I have problem with NVDA and JAWS reader on the dropdown list. It is the dropdown autocomplete list, and when I am navigating with the keyboard,it was reading double values from the dropdown list.

Then I have added aria-hidden="true", and now it is reading the first alphabet of the value, than the value. For example : dropdown list: car apple watch it is reading: c car a apple w watch.. What should I do to read only values?
