我目前正在开发一个需要自定义滑块的项目,并且我迅速抓取了一个看起来整洁的Web教程,然后离开,并且静态地工作得很好。Javascript滑块功能 - 如何客观化选择器?
现在我想能够在我的页面上放几个滑块,因此需要动态地添加控件,而不是像下面所做的那样仅仅使用jQuery来选择某个滑块。
这是我与评论的代码加入到解释什么即时试图实现:
var Slider = function() { this.initialize.apply(this, arguments) };
Slider.prototype = {
initialize: function(slider) {
this.ul = slider.children[2];
this.li = this.ul.children;
this.nav = slider.children[3]; //Why cant i use .append on this element?
// make <ul> as large as all <li>’s
this.ul.style.width = (100 * this.li.length) + '%';
// set width of the li's
for(i = 0; i < this.li.length; i++) {
this.li[i].style.width = (100/this.li.length) + '%';
$(".slider-nav").append('<div class="slider-dot"></div>'); //Want to make it a this.nav or something similar instead of an external selector
//console.log(this.nav);
}
this.currentIndex = 0;
},
goTo: function(index) {
if (index < 0 || index > this.li.length - 1)
return;
// move <ul> left
this.ul.style.left = '-' + (100 * index) + '%';
this.currentIndex = index
},
goToPrev: function() {
this.goTo(this.currentIndex - 1)
},
goToNext: function() {
this.goTo(this.currentIndex + 1)
}}
var sliders = [];
$('.slider').each(function() {
sliders.push(new Slider(this));
});
//Find a way to implement theese 2 within the slider function, how to find out what position in the array a slider has?
$(".prev-btn").click(function() {
sliders[0].goToPrev();
});
$(".next-btn").click(function() {
sliders[0].goToNext();});
的痕迹了滑块看起来是这样的:http://puu.sh/hAUH1/a865792137.png
