Ro‘yxatni filtrlash
Ro‘yxatdagi elementlarni qidirish uchun JavaScript’dan qanday foydalanish mumkin.
Qidiruvli ro‘yxat yaratish
1-qadam) HTML qo‘shing:
Misol
<input type="text" id="myInput" onkeyup="myFunction()" placeholder="Search for names..">
<ul id="myUL">
<li><a href="#">Adele</a></li>
<li><a href="#">Agnes</a></li>
<li><a href="#">Billy</a></li>
<li><a href="#">Bob</a></li>
<li><a href="#">Calvin</a></li>
<li><a href="#">Christina</a></li>
<li><a href="#">Cindy</a></li>
</ul>
Eslatma: Bu namoyishda href="#" dan foydalanamiz, chunki havola beriladigan sahifamiz yo‘q. Haqiqiy loyihada bu muayyan sahifaga olib boradigan haqiqiy URL bo‘lishi kerak.
2-qadam) CSS qo‘shing:
Kiritish elementi va ro‘yxatga uslub bering:
Misol
#myInput {
background-image: url('/css/searchicon.png'); /* Add a search icon to input */
background-position: 10px 12px; /* Position the search icon */
background-repeat: no-repeat; /* Do not repeat the icon image */
width: 100%; /* Full-width */
font-size: 16px; /* Increase font-size */
padding: 12px 20px 12px 40px; /* Add some padding */
border: 1px solid #ddd; /* Add a grey border */
margin-bottom: 12px; /* Add some space below the input */
}
#myUL {
/* Remove default list styling */
list-style-type: none;
padding: 0;
margin: 0;
}
#myUL li a {
border: 1px solid #ddd; /* Add a border to all links */
margin-top: -1px; /* Prevent double borders */
background-color: #f6f6f6; /* Grey background color */
padding: 12px; /* Add some padding */
text-decoration: none; /* Remove default text underline */
font-size: 18px; /* Increase the font-size */
color: black; /* Add a black text color */
display: block; /* Make it into a block element to fill the whole list */
}
#myUL li a:hover:not(.header) {
background-color: #eee; /* Add a hover effect to all links, except for headers */
}
3-qadam) JavaScript qo‘shing:
Misol
<script>
function myFunction() {
// Declare variables
var input, filter, ul, li, a, i, txtValue;
input = document.getElementById('myInput');
filter = input.value.toUpperCase();
ul = document.getElementById("myUL");
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[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>

Maslahat: Katta-kichik harflarni farqlaydigan qidiruv kerak bo‘lsa, toUpperCase() ni olib tashlang.
