我正在尝试为 WordPress 制作一个带有一些基本控件的图像 slider 插件。
<小时/>当我按下“下一步”按钮时,我在 Chrome 上收到此错误:
Uncaught ReferenceError: sliders is not defined
at <anonymous>:1:1
(anonymous) @ VM18633:1
我觉得我已经尝试了一切..
这是我的插件 (php) 文件。
/* Shortcode */
add_shortcode( 'lk_slider', 'lk_main_slider' );
/* Main function */

slider.js
var Slider = function() { this.initialize.apply(this, arguments) }
Slider.prototype = {
initialize: function(slider) {
this.ul = slider.children[0]
this.li = this.ul.children
// make <ul> as large as all <li>’s
this.ul.style.width = (this.li[0].clientWidth * this.li.length) + 'px'
this.currentIndex = 0
},
goTo: function(index) {
// filter invalid indices
if (index < 0 || index > this.li.length - 1)
return
// move <ul> left
this.ul.style.left = '-' + (100 * index) + '%'

buttons.js
var sliders = []
$('.slider').each(function() {
sliders.push(new Slider(this))
})
样式.css
.lk-plugin-slider {
width: 400px;
height: 300px;
overflow: hidden;
position: relative; /* for overflow: hidden to work in IE7 */
}
/* styled by JS to match the added width and height of all <li>’s */
.lk-plugin-slider > ul {
position: relative;

-webkit-transition: .5s left;

-ms-transition: .5s left;
-o-transition: .5s left;
list-style: none;
margin: 0;
padding: 0;

.lk-plugin-slider > ul > li {
float: left;

}
/* title */
.lk-slider-title {
margin-top: -47%;
margin-left: 5%;
color: white;
}
/* text */
.lk-slider-text {
margin-left: 5%;
color: white;
}
我会接受任何我能得到的帮助。谢谢!

忘记分号:
var sliders = []; // <-- here
$('.slider').each(function() {
sliders.push(new Slider(this))
})
