Berkongsi contoh kod untuk JavaScript untuk melaksanakan penukaran gelongsor kemahiran images_javascript

Anggapkan kita mempunyai lima gambar bmp dari 1 hingga 5, maka kod teras yang mengawal paparan penukaran gambar boleh menjadi:

<script>
 var i=1;
 var img = new Array();
 img[0] = "1.bmp";
 img[1] = "2.bmp";
 img[2] = "3.bmp";
 img[3] = "4.bmp";
 img[4] = "5.bmp";
 function playImg(){
 i=i+1;
 var imgs = document.getElementById("img");
 imgs.src =img[i];
 if(i>=4){
 i=1;
 }
 }
 window.onload = function(){
 document.getElementById("img").src="1.bmp";
 }
</script>
<img id="img" src="" width="500" hieght="500" onclick="playImg()" style="cursor:pointer;">

Ia terutamanya merangkumi idea kawalan pensuisan gambar dan boleh digunakan dalam pelbagai senario Jadi mari kita lihat pelaksanaan yang lebih kompleks yang boleh mengawal peristiwa gelongsor dan jeda serta contoh khusus lain untuk merealisasikan kesan pensuisan gelongsor gambar:

var $$ = function (id) {
return "string" == typeof id ? document.getElementById(id) : id;
};
var Extend = function(destination, source) {
for (var property in source) {
 destination[property] = source[property];
}
return destination;
}
var CurrentStyle = function(element){
return element.currentStyle || document.defaultView.getComputedStyle(element, null);
}
var Bind = function(object, fun) {
var args = Array.prototype.slice.call(arguments).slice(2);
return function() {
 return fun.apply(object, args.concat(Array.prototype.slice.call(arguments)));
}
}
var forEach = function(array, callback, thisObject){
if(array.forEach){
 array.forEach(callback, thisObject);
}else{
 for (var i = 0, len = array.length; i < len; i++) { callback.call(thisObject, array[i], i, array); }
}
}
var Tween = {
Quart: {
 easeOut: function(t,b,c,d){
 return -c * ((t=t/d-1)*t*t*t - 1) + b;
 }
},
Back: {
 easeOut: function(t,b,c,d,s){
 if (s == undefined) s = 1.70158;
 return c*((t=t/d-1)*t*((s+1)*t + s) + 1) + b;
 }
},
Bounce: {
 easeOut: function(t,b,c,d){
 if ((t/=d) < (1/2.75)) {
 return c*(7.5625*t*t) + b;
 } else if (t < (2/2.75)) {
 return c*(7.5625*(t-=(1.5/2.75))*t + .75) + b;
 } else if (t < (2.5/2.75)) {
 return c*(7.5625*(t-=(2.25/2.75))*t + .9375) + b;
 } else {
 return c*(7.5625*(t-=(2.625/2.75))*t + .984375) + b;
 }
 }
}
}
