I’m a beginner in Javascript/HTML/CSS. So I’m sorry if I’m missing something obvious.
My Task: I want to create a search bar on my website (website for images). With this search bar the user should be able to search for “keywords” which I will determine in a list. Every item in my list should lead the user to a new html site.
My Problem: The list that i have created is visible under the search input. But I want to hide the list at first and just show the suggestions or matches from what the user enters in the search bar. But if I hide the list in css, it’s obviously also not gonna show the matches when theres something typed in the input. I included code and screenshots at the bottom. Thanks!
<input type="text" id="myInput" onkeyup="myFunction()" placeholder="Search for Topic.." title="Type in a name"> <ul id="myUL"> <li><a href="shuffle4.html">School</a></li> <li><a href="shuffle4.html">Sport</a></li> <li><a href="shuffle4.html">Tennis</a></li> <li><a href="shuffle4.html">Work</a></li> <li><a href="shuffle4.html">Funny</a></li> <li><a href="shuffle4.html">Money</a></li> <li><a href="shuffle4.html">Food</a></li> </ul> <script> function myFunction() { var input, filter, ul, li, a, i, txtValue; input = document.getElementById("myInput"); filter = input.value.toUpperCase(); ul = document.getElementById("myUL"); li = ul.getElementsByTagName("li"); for (i = 0; i < li.length; i++) { a = li[i].getElementsByTagName("a")[0]; txtValue = a.textContent || a.innerText; if (txtValue.toUpperCase().indexOf(filter) > -1) { li[i].style.display = ""; } else { li[i].style.display = "none"; } } } </script>
Screenshots: All the suggestions from my list are showing, how can i hide them if nothing is typed in the input?

You can use the same idea you’ve already used in the <li>
, use display: none
to hide the element, then on every call of myFunction()
, check the content of the <input>
and edit the <ul>
style accordingly:
// If we've got more than 1 char in <input>, show it, otherwise, hide const inputDisplay = input.value.length > 1 ? 'block' : 'none'; ul.style.display = inputDisplay;
function myFunction() { var input, filter, ul, li, a, i, txtValue; input = document.getElementById("myInput"); filter = input.value.toUpperCase(); ul = document.getElementById("myUL"); li = ul.getElementsByTagName("li"); // If we've got more than 1 char in <input>, show it, otherwise, hide const inputDisplay = input.value.length > 1 ? 'block' : 'none'; ul.style.display = inputDisplay; for (i = 0; i < li.length; i++) { a = li[i].getElementsByTagName("a")[0]; txtValue = a.textContent || a.innerText; if (txtValue.toUpperCase().indexOf(filter) > -1) { li[i].style.display = ""; } else { li[i].style.display = "none"; } } }
ul { display: none; }
<input type="text" id="myInput" onkeyup="myFunction()" placeholder="Search for Topic.." title="Type in a name"> <ul id="myUL"> <li><a href="shuffle4.html">School</a></li> <li><a href="shuffle4.html">Sport</a></li> <li><a href="shuffle4.html">Tennis</a></li> <li><a href="shuffle4.html">Work</a></li> <li><a href="shuffle4.html">Funny</a></li> <li><a href="shuffle4.html">Money</a></li> <li><a href="shuffle4.html">Food</a></li> </ul>
