微信小程序开发案例附代码
以下是一个简单的微信小程序分类栏开发代码示例:
1. 在 `app.json` 文件中添加 `tabBar` 字段,定义分类栏的样式和图标:
```
"tabBar": {
"list": [
{
"pagePath": "pages/home/home",
"text": "首页",
"iconPath": "images/home.png",
"selectedIconPath": "images/home_selected.png"
},
{
"pagePath": "pages/category/category",
"text": "分类",
"iconPath": "images/category.png",
"selectedIconPath": "images/category_selected.png"
},
{
"pagePath": "pages/cart/cart",
"text": "购物车",
"iconPath": "images/cart.png",
"selectedIconPath": "images/cart_selected.png"
},
{
"pagePath": "pages/profile/profile",
"text": "我的",
"iconPath": "images/profile.png",
"selectedIconPath": "images/profile_selected.png"
}
]
}
```
2. 在 `pages` 目录下创建分类页面 `category` ,并在 `category.json` 文件中定义页面样式:
```
{
"navigationBarTitleText": "分类",
"usingComponents": {},
"style": {}
}
```
3. 在 `category.wxml` 文件中编写页面结构代码:
```
<view class="category">
<view class="category-list">
<view class="category-item" wx:for="{{categoryList}}" wx:key="{{item.id}}">
<image src="{{item.image}}" class="category-image"></image>
<text class="category-name">{{item.name}}</text>
</view>
</view>
</view>
```
4. 在 `category.js` 文件中编写页面逻辑代码:
```
Page({
data: {
categoryList: [
{
id: 1,
name: "水果",
image: "/images/fruit.png"
},
{
id: 2,
name: "蔬菜",
image: "/images/vegetable.png"
},
{
id: 3,
name: "零食",
image: "/images/snack.png"
}
]
}
})
```
5. 在 `app.wxss` 文件中定义页面样式:
```
.category {
background-color: #f5f5f5;
height: 100%;
}
.category-list {
display: flex;
flex-wrap: wrap;
justify-content: space-between;
padding: 20rpx;
}
.category-item {
width: 30%;
margin-bottom: 20rpx;
background-color: #fff;
border-radius: 10rpx;
overflow: hidden;
box-shadow: 2rpx 2rpx 5rpx #ccc;
}
.category-image {
width: 100%;
height: 200rpx;
object-fit: cover;
}
.category-name {
display: block;
padding: 10rpx;
font-size: 28rpx;
text-align: center;
}
```
通过以上步骤,我们就完成了微信小程序分类栏的开发。
