I've got two ULs with IDs 'ul1' and 'ul2'. JS: function journalsearch() { // Declare variables var input, filter, ul, li, a, i, txtValue; input = document.getElementById('myInput'); filter = input.value.toUpperCase(); ul = document.getElementById('ul1','ul2'); li = ul.getElementsByTagName('li'); // Loop through all list items, and hide those who don't match the search query for (i = 0; i < li.length; i++) { a = li.getElementsByTagName("a")[0]; txtValue = a.textContent || a.innerText; if (txtValue.toUpperCase().indexOf(filter) > -1) { li.style.display = ""; } else { li.style.display = "none"; } } } Search box: <input type="text" id="input1" onkeyup="journalsearch('ul1','ul2')" placeholder="Search for titles..."> Search filters the first list as expected, but nothing happens to the second.

Doesn't seem to be working for me - do any changes need to be made to the original for loop?

I had thought about using a class rather than ID but am not sure how to approach that.

I'm basically trying to replicate https://www.w3schools.com/howto/howto_js_filter_lists.asp but with multiple ULs rather than a single one. I've had no problem with the HTML/CSS adaptations, but am stuck on the JS. Can anyone help?
