Html .CSS JQUERY (magnifier)实现详情页面特效

一、jquery使用技巧

1、jquery操作css

2、jquery hover()方法

3、轮播图插件unslider

4、jqeury click()方法(扩展:方法的重载overload)

5、图片放大插件jQueryMagnifier

6、jquery设置内容和属性

7、jquery添加、删除元素

二、任务

1、首页(轮播图、鼠标悬停效果)

(1)读一遍轮播图的demo代码(页面标签元素、标签样式效果、jquery代码)

jquery轮播图插件unslider

(2)准备并配置好插件的相关文件(js文件、图片)

(3)粘贴demo代码

(4)修改属性(高宽、颜色、形状等CSS样式)和参数(id名称、class名称、图片路径)

2、商品详细页面(商品重量样式切换、图片放大镜

(1)准备并配置好插件相关文件(css、js、图片)

(2)编写html和js代码

注意:修改css里的图片路径和html里的图片路径

(3)图代码,并修改相关属性参数(高宽、颜色、形状等CSS样式)

扩展作业:

(1)重载的定义:

概念: 在同一的类中,允许在一个以上的同名方法,只要他们的参数的个数或者参数类型不同即可 特点:与返回值类型无关,只看参数列表,切参数列表必须不同。(参数个数或参数类型)。调用时,根据方法参数列表的不同来区分;

(2)用重载实现:在js中用方法重载实现,设置边框宽度(1个参数上下左右全一样,2个参数先上下后左右,4个参数上右下左)

三、实现过程代码
