DIVCSS布局實例：一款漂亮的圖片切換效果(可以控制播放)_DIV+CSS實例

這是一款圖片切換效果，主要是應用DIV CSS進行布局，以javascript作為腳本來實現這樣的效果。
請您非凡注重，本例效果在FF下無效。
最終效果如圖：
我們來看HTML代碼：
示例代碼 [m.ghpqjb.com]
<div id="mContainer"></div>
<input class="btn" id="pauseBtn" onclick="doPause();" type="button" value="pause" />
<input class="btn" id="pauseBtn" onclick="doPause();" type="button" value="pause" />
建立一個層，設置id為mContainer，作為圖片的容器層。
設置一個按鈕來控制圖片切換的暫停與繼續。
我們看下面的CSS代碼：
示例代碼 [m.ghpqjb.com]
#mContainer {
width:225px;
position:relative;
height:168px;;
}
.mPhoto {
filter:Alpha(opacity=0);
left:0px;
position:absolute;
top:0px;
moz-opacity:0.0;
}
.btn {
border-right:#000 1px solid;
border-top:#000 1px solid;
margin-top:5px;
font-size:9px;
border-left:#000 1px solid;
width:40px;
border-bottom:#000 1px solid;
font-family:verdana;
}
width:225px;
position:relative;
height:168px;;
}
.mPhoto {
filter:Alpha(opacity=0);
left:0px;
position:absolute;
top:0px;
moz-opacity:0.0;
}
.btn {
border-right:#000 1px solid;
border-top:#000 1px solid;
margin-top:5px;
font-size:9px;
border-left:#000 1px solid;
width:40px;
border-bottom:#000 1px solid;
font-family:verdana;
}
這些代碼我們都能看明白，需要指出的是類mPhoto的樣式定義。
主要是應用了濾鏡將圖片的透明度設置為零，完全透明。
我們看下面的javascript腳本：
示例代碼 [m.ghpqjb.com]
var currentPhoto = 0;
var secondPhoto = 1;
var currentOpacity = new Array();
var imageArray = new Array("1.jpg","2.jpg","3.jpg","4.jpg","5.jpg","6.jpg","7.jpg","8.jpg");
var FADE_STEP = 2;
var FADE_INTERVAL = 10;
var pause = false;
function init() {
currentOpacity[0]=99;
for(i=1;i<imageArray.length;i )currentOpacity[i]=0;
mHTML="";
for(i=0;i<imageArray.length;i )mHTML ="<div id=\"photo\" name=\"photo\" class=\"mPhoto\"><img src=\"" _fcksavedurl="\""" imageArray[i] "\"></div>";
document.getElementById("mContainer").innerHTML = mHTML;
if(document.all) {
document.getElementsByName("photo")[currentPhoto].style.filter="alpha(opacity=100)";
} else {
document.getElementsByName("photo")[currentPhoto].style.MozOpacity = .99;
}
mInterval = setInterval("crossFade()",FADE_INTERVAL);
}
function crossFade() {
if(pause)return;
currentOpacity[currentPhoto]-=FADE_STEP;
currentOpacity[secondPhoto] = FADE_STEP;
if(document.all) {
document.getElementsByName("photo")[currentPhoto].style.filter = "alpha(opacity=" currentOpacity[currentPhoto] ")";
document.getElementsByName("photo")[secondPhoto].style.filter = "alpha(opacity=" currentOpacity[secondPhoto] ")";
} else {
document.getElementsByName("photo")[currentPhoto].style.MozOpacity = currentOpacity[currentPhoto]/100;
document.getElementsByName("photo")[secondPhoto].style.MozOpacity =currentOpacity[secondPhoto]/100;
}
if(currentOpacity[secondPhoto]/100>=.98) {
currentPhoto = secondPhoto;
secondPhoto ;
if(secondPhoto == imageArray.length)secondPhoto=0;
pause = true;
xInterval = setTimeout("pause=false",2000);
}
}
function doPause() {
if(pause) {
pause = false;
document.getElementById("pauseBtn").value = "pause";
} else {
pause = true;
document.getElementById("pauseBtn").value = "play";
}
}
var secondPhoto = 1;
var currentOpacity = new Array();
var imageArray = new Array("1.jpg","2.jpg","3.jpg","4.jpg","5.jpg","6.jpg","7.jpg","8.jpg");
var FADE_STEP = 2;
var FADE_INTERVAL = 10;
var pause = false;
function init() {
currentOpacity[0]=99;
for(i=1;i<imageArray.length;i )currentOpacity[i]=0;
mHTML="";
for(i=0;i<imageArray.length;i )mHTML ="<div id=\"photo\" name=\"photo\" class=\"mPhoto\"><img src=\"" _fcksavedurl="\""" imageArray[i] "\"></div>";
document.getElementById("mContainer").innerHTML = mHTML;
if(document.all) {
document.getElementsByName("photo")[currentPhoto].style.filter="alpha(opacity=100)";
} else {
document.getElementsByName("photo")[currentPhoto].style.MozOpacity = .99;
}
mInterval = setInterval("crossFade()",FADE_INTERVAL);
}
function crossFade() {
if(pause)return;
currentOpacity[currentPhoto]-=FADE_STEP;
currentOpacity[secondPhoto] = FADE_STEP;
if(document.all) {
document.getElementsByName("photo")[currentPhoto].style.filter = "alpha(opacity=" currentOpacity[currentPhoto] ")";
document.getElementsByName("photo")[secondPhoto].style.filter = "alpha(opacity=" currentOpacity[secondPhoto] ")";
} else {
document.getElementsByName("photo")[currentPhoto].style.MozOpacity = currentOpacity[currentPhoto]/100;
document.getElementsByName("photo")[secondPhoto].style.MozOpacity =currentOpacity[secondPhoto]/100;
}
if(currentOpacity[secondPhoto]/100>=.98) {
currentPhoto = secondPhoto;
secondPhoto ;
if(secondPhoto == imageArray.length)secondPhoto=0;
pause = true;
xInterval = setTimeout("pause=false",2000);
}
}
function doPause() {
if(pause) {
pause = false;
document.getElementById("pauseBtn").value = "pause";
} else {
pause = true;
document.getElementById("pauseBtn").value = "play";
}
}
