JQuery幻灯片，可点击编号位置
JQuery Slideshow with clickable numbered position
好吧，我有一些问题，我要用播放、暂停、下一个和上一个按钮制作我自己的Jquery幻灯片。我想让我的幻灯片带编号的图像成为当前数字，并且可以点击，所以图像在第4位，但我想点击数字进入第2位。我在谷歌和这个网站上搜索，但很难找到，因为使用Jquery插件有很多参考，但我正在学习Jquery，所以我没有使用插件。
他们是否必须使用数组对图像进行排序，并且有编号列表？
这是我的代码。HTML:

CSS：

height : 200px;
top : 20px;

}
.item {
position : absolute;

.first{

li {
display : inline-block;
padding : 5px;
border : 1px solid #ccc;
background-color : #eee;
cursor : pointer;
}
#play {
display : none;
}
Jquery：
var timeoutId;
var slideImage = function( step ) {
if ( step == undefined ) step = 1;
//Clear timeout if any
clearTimeout ( timeoutId );
//Get current image's index
var indx = $('.item:visible').index('.item');
//If step == 0, we don't need to do any fadein our fadeout
if ( step != 0 ) {
//Fadeout this item
$('.item:visible').fadeOut();
}
//Increment for next item
indx = indx + step ;
//Check bounds for next item
if ( indx >= $('.item').length ) {
indx = 0;
} else if ( indx < 0 ) {
indx = $('.item').length - 1;
}
//If step == 0, we don't need to do any fadein our fadeout
if ( step != 0 ) {
//Fadein next item
$('.item:eq(' + indx + ')').fadeIn();
}
//Set Itmeout
timeoutId = setTimeout ( slideImage, 5000 );
};
//Start sliding
slideImage(0);
//When clicked on prev
$('#prev').click(function() {
//slideImage with step = -1
slideImage (-1);
});
//When clicked on next
$('#next').click(function() {
//slideImage with step = 1
slideImage (1);
});
//When clicked on Pause
$('#pause').click(function() {
//Clear timeout
clearTimeout ( timeoutId );
//Hide Pause and show Play
$(this).hide();
$('#play').show();
});
//When clicked on Play
$('#play').click(function() {
//Start slide image
slideImage(0);
//Hide Play and show Pause
$(this).hide();
$('#pause').show();
});
$(document).ready(function(){
var sliderwidth = 500;
$('#navigation li').bind('click',function() {
$('.slider').animate({left:"-" + sliderwidth * $(this).index() },1000);
});
});
我添加了
- 每张图片的ID
- 当前显示的图像的全局变量
- 单击链接时将调用的函数，该函数将调用您的函数slideImage
