图像无法使用Javascript Image Slider滑动

[英]Images won't slide with Javascript Image Slider

 原文  2014-07-15 05:34:13  4   2    javascript/ jquery/ html/ css/ slider

问题描述

我正在尝试为婚礼网站创建一个简单的图像滑块。 我已经完成了html / css / javascript /。 我已经下载了jQuery并将其链接到HTML上，但是图像不会向左或向右滑动。

目前，我只有4张图片，但想添加其他图片。 两个问题：1）为什么我的图像没有左右滑动。 2）即使我将img或.gallery img中CSS的宽度更改为100％，我似乎也无法使图像完整显示。

您在代码中有一些小错误。 看到小提琴 

    $('.rightbttn').click(function() {
        moveLeft();
    });
    $('.leftbttn').click(function() {
        moveRight();
    });
