The example in this article describes the jQuery simple custom image carousel plug-in and its usage. Share it with everyone for your reference, the details are as follows:
I often use other people’s plug-ins, now I write one myself to commemorate it.
jQuery.banner.js:
/*
* banner 0.1
* 使用banner 实现图片定时切换 鼠标经过停止动画
* 鼠标离开，继续动画
*/
;(function($){
$.fn.banner =function(options){
//各种属性和参数
var defaults ={
picWidth:"1000",
picHeight:"300",
speed:"1500"
};
var totalW = 0; //保存总的动画宽度
var timer = null; //保存定时器
var current = 0; //保存当前动画到第N张图，下次从这里开始
var totalNum = 0; //保存总的图数
var Dsqtime = 0; //定义定时器时间 【外传参数】
var Dhtime = 0; //定义动画时间
var count = 0 ;
//合并多个对象为一个，即有新参数 用新的，否则用默认的
var options = $.extend(defaults, options);
this.each(function(){
//实现代码
var __this = $(this);
Dsqtime = options.speed;
Dhtime = Dsqtime/3;
//初始化
init(__this);
//调用动画
show(__this, options.picWidth,current);
//鼠标经过时事件
__this.find('ul li').bind('mouseover',function(){
window.clearInterval(timer); //清除定时器
});
__this.find('ul li').bind('mouseout',function(){
show(__this, options.picWidth,current);
//接着上一次动画轮播
});
});
//初始化 设定父容器宽度
function init(obj){
obj.find('ul li').each(function(){
totalW += $(this).width();
totalNum++;
});
obj.find('ul').width(totalW);
}
//开始动画显示
function show(obj, width, current){
timer = setInterval(function(){
obj.find('ul').animate({'margin-left':'-'+count*width+'px'},
Dhtime);
current = count;
count++;
if(count == totalNum){
count =0;
}
}, Dsqtime);
}
};
