လုပ်နည်း - Slideshow လုပ်နည်း
CSS နှင့် JavaScript ဖြင့် တုံ့ပြန်မှုရှိသော စလိုက်ရှိုးတစ်ခုကို ဖန်တီးနည်းကို လေ့လာပါ။
ဆလိုက်ရှိုး / ချားရဟတ်
ဒြပ်စင်များမှတဆင့် လည်ပတ်ရန် စလိုက်ရှိုးကို အသုံးပြုသည်-
Slideshow တစ်ခုဖန်တီးပါ။
အဆင့် 1) HTML ကိုထည့်ပါ
ဥပမာ
<!-- Slideshow container -->
<div class="slideshow-container">
<!-- Full-width images with number and caption text -->
<div class="mySlides fade">
<div class="numbertext">1 / 3</div>
<img src="img1.jpg"
style="width:100%">
<div class="text">Caption
Text</div>
</div>
<div class="mySlides fade">
<div class="numbertext">2 / 3</div>
<img src="img2.jpg"
style="width:100%">
<div class="text">Caption
Two</div>
</div>
<div class="mySlides fade">
<div class="numbertext">3 / 3</div>
<img src="img3.jpg"
style="width:100%">
<div class="text">Caption
Three</div>
</div>
<!-- Next and previous
buttons -->
<a class="prev" onclick="plusSlides(-1)">❮</a>
<a class="next" onclick="plusSlides(1)">❯</a>
</div>
<br>
<!-- The dots/circles -->
<div style="text-align:center">
<span class="dot" onclick="currentSlide(1)"></span>
<span class="dot" onclick="currentSlide(2)"></span>
<span class="dot" onclick="currentSlide(3)"></span>
</div>
အဆင့် 2) CSS ကိုထည့်ပါ
နောက်နှင့် ယခင်ခလုတ်များ၊ စာတန်းစာသားနှင့် အစက်များကို ပုံစံထုတ်ပါ-
ဥပမာ
* {box-sizing:border-box}
/* Slideshow container */
.slideshow-container {
max-width: 1000px;
position:
relative;
margin: auto;
}
/* Hide the images by default */
.mySlides {
display: none;
}
/* Next & previous buttons */
.prev, .next {
cursor: pointer;
position: absolute;
top: 50%;
width: auto;
margin-top: -22px;
padding: 16px;
color:
white;
font-weight: bold;
font-size: 18px;
transition: 0.6s ease;
border-radius: 0 3px 3px 0;
user-select: none;
}
/*
Position the "next button" to the right */
.next {
right: 0;
border-radius: 3px 0 0 3px;
}
/* On hover, add
a black background color with a little bit see-through */
.prev:hover, .next:hover {
background-color: rgba(0,0,0,0.8);
}
/* Caption text */
.text {
color: #f2f2f2;
font-size: 15px;
padding:
8px 12px;
position: absolute;
bottom: 8px;
width: 100%;
text-align: center;
}
/* Number text (1/3
etc) */
.numbertext {
color: #f2f2f2;
font-size:
12px;
padding: 8px 12px;
position: absolute;
top: 0;
}
/* The dots/bullets/indicators */
.dot {
cursor: pointer;
height: 15px;
width: 15px;
margin: 0 2px;
background-color: #bbb;
border-radius: 50%;
display:
inline-block;
transition: background-color 0.6s ease;
}
.active, .dot:hover {
background-color: #717171;
}
/*
Fading animation */
.fade {
-webkit-animation-name:
fade;
-webkit-animation-duration: 1.5s;
animation-name:
fade;
animation-duration: 1.5s;
}
@-webkit-keyframes
fade {
from {opacity: .4}
to {opacity: 1}
}
@keyframes
fade {
from {opacity: .4}
to {opacity: 1}
}
အဆင့် 3) JavaScript ကိုထည့်ပါ။
ဥပမာ
var slideIndex = 1;
showSlides(slideIndex);
// Next/previous controls
function plusSlides(n)
{
showSlides(slideIndex += n);
}
// Thumbnail image controls
function currentSlide(n) {
showSlides(slideIndex = n);
}
function showSlides(n) {
var i;
var slides = document.getElementsByClassName("mySlides");
var dots = document.getElementsByClassName("dot");
if (n >
slides.length) {slideIndex = 1}
if (n < 1) {slideIndex =
slides.length}
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
for (i = 0; i <
dots.length; i++) {
dots[i].className = dots[i].className.replace("
active", "");
}
slides[slideIndex-1].style.display = "block";
dots[slideIndex-1].className += " active";
}
အလိုအလျောက်ဆလိုက်ရှိုး
အလိုအလျောက်ဆလိုက်ရှိုးတစ်ခုပြသရန်၊ အောက်ပါကုဒ်ကို အသုံးပြုပါ။
ဥပမာ
var slideIndex = 0;
showSlides();
function showSlides() {
var i;
var slides = document.getElementsByClassName("mySlides");
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
slideIndex++;
if (slideIndex > slides.length) {slideIndex
= 1}
slides[slideIndex-1].style.display = "block";
setTimeout(showSlides, 2000); // Change image every 2
seconds
}
ဆလိုက်ရှိုးများစွာ
ဥပမာ
var slideIndex = [1,1];
/* Class the members of each slideshow group with
different CSS classes */
var slideId = ["mySlides1", "mySlides2"]
showSlides(1, 0);
showSlides(1, 1);
function plusSlides(n, no) {
showSlides(slideIndex[no] += n, no);
}
function showSlides(n, no) {
var i;
var x = document.getElementsByClassName(slideId[no]);
if (n > x.length) {slideIndex[no] = 1}
if (n < 1) {slideIndex[no] =
x.length}
for (i = 0; i < x.length; i++) {
x[i].style.display = "none";
}
x[slideIndex[no]-1].style.display
= "block";
}
