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;function initgallery(){
    for(var i=0; i       document.getelementbyid(fpic+i).style.display = none;
       document.getelementbyid(ftitl+i).style.display = none;
       document.getelementbyid(fnum+i).style.classname = numoff;
    }
    startchange();
    settimer();
}
function startchange(){
    index = index % 4;
    changepic(index);
    changetitl(index);
    changenum(index);
    index++;
}
function changepic(index){
    for(var i=0; i        document.getelementbyid(fpic+i).style.display = none;
    }
    document.getelementbyid(fpic+index).style.display = block;
}
function changetitl(index){
    for(var i=0; i        document.getelementbyid(ftitl+i).style.display = none;
    }
    document.getelementbyid(ftitl+index).style.display = block;
}
function changenum(index){
    for(var i=0; i        document.getelementbyid(fnum+i).classname = numoff;
    }
    document.getelementbyid(fnum+index).classname = numoff numon;
}
function cleartimer(){
    this.clearinterval(timer);
}
function settimer(){
    timer = window.setinterval(startchange, 3000)
}
function setindex(index){
    this.index = index;
    this.startchange();
}
