下面这段代码是用来实现图片新闻的
复制代码代码如下:
Var-Index = 0;
var Timer = null;
Funktion initGallery(){
for(var i=0; i< 4; i++){
document.getElementById("fPic"+i).style.display = "none";
document.getElementById("fTitl"+i).style.display = "none";
document.getElementById("fNum"+i).style.className = "numOff";
}
startChange();
setTimer();
}
Funktion startChange(){
Index = Index % 4;
changePic(index);
changeTitl(index);
changeNum(index);
index++;
}
Funktion changePic(index){
for(var i=0; i<4;i++){
document.getElementById("fPic"+i).style.display = "none";
}
document.getElementById("fPic"+index).style.display = "block";
}
Funktion changeTitl(index){
for(var i=0; i<4; i++){
document.getElementById("fTitl"+i).style.display = "none";
}
document.getElementById("fTitl"+index).style.display = "block";
}
Funktion changeNum(index){
for(var i=0; i<4; i++){
document.getElementById("fNum"+i).className = "numOff";
}
document.getElementById("fNum"+index).className = "numOff numOn";
}
Funktion clearTimer(){
this.clearInterval(Timer);
}
Funktion setTimer(){
Timer = window.setInterval(startChange, 3000)
}
Funktion setIndex(index){
this.index = index;
this.startChange();
}
