二.JS部分:
utils.js文件
function toggle(eles, active) {
//封装函数、图片显示的部分、传入获取到的div，和被点击的序号
for (var i = eles.length; i--;) {
eles[i].className = "item"; //先让所有div隐藏
}
eles[active].className = "item active"; //再让被点击的序号对应的div 显示
}
//下一页
window.onload=function(){
var abtn = document.getElementsByClassName("btn");
var aItem = document.getElementsByClassName("item");
var nowPage = 0; //定义当前也，默认值为0
for (var i = abtn.length; i--;) {
abtn[i].tab = i;
abtn[i].onclick = function() {
toggle(aItem, this.tab);
nowPage = this.tab //被点击后，保存当前页的序号
}
}
var next = document.getElementsByClassName("next");
next[0].onclick = function() {
nowPage++;
nowPage %= abtn.length;
toggle(aItem, nowPage);
}
//上一页
var prev = document.getElementsByClassName("pre");
prev[0].onclick = function() {
nowPage--;
if (nowPage == -1) {
nowPage = abtn.length - 1;
}
toggle(aItem, nowPage);
}
}
