Qidiruv menyusi
JavaScript yordamida havolalarni filtrlaydigan qidiruv menyusini yaratishni o‘rganing.
Qidiruv/filtr menyusi
Navigatsiya menyusida havolalarni qanday qidirish mumkin:
Page Content
Qidiruv variantlarini "filtrlash" uchun qidiruv satriga kerakli kategoriya/havola nomini yozishni boshlang.
Some text..Some text..Some text..Some text..Some text..Some text..Some text..Some text..
Some other text..Some text..Some text..Some text..Some text..Some text..Some text..Some text..
Some text..
Qidiruv menyusini yaratish
1-qadam) HTML qo‘shing:
Misol
<input type="text" id="mySearch" onkeyup="myFunction()" placeholder="Search.." title="Type in a category">
<ul id="myMenu">
<li><a href="#">HTML</a></li>
<li><a href="#">CSS</a></li>
<li><a href="#">JavaScript</a></li>
<li><a href="#">PHP</a></li>
<li><a href="#">Python</a></li>
<li><a href="#">jQuery</a></li>
<li><a href="#">SQL</a></li>
<li><a href="#">Bootstrap</a></li>
<li><a href="#">Node.js</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:
Qidiruv maydoni va navigatsiya menyusiga uslub bering:
Misol
/* Style the search box */
#mySearch {
width: 100%;
font-size: 18px;
padding: 11px;
border: 1px solid #ddd;
}
/* Style the navigation menu */
#myMenu {
list-style-type: none;
padding: 0;
margin: 0;
}
/* Style the navigation links */
#myMenu li a {
padding: 12px;
text-decoration: none;
color: black;
display: block
}
#myMenu li a:hover {
background-color: #eee;
}
3-qadam) JavaScript qo‘shing:
Misol
<script>
function myFunction() {
// Declare variables
var input, filter, ul, li, a, i;
input = document.getElementById("mySearch");
filter = input.value.toUpperCase();
ul = document.getElementById("myMenu");
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];
if (a.innerHTML.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.
