看到一个需求,对一些前端小白或者刚开始写小程序的人来说,可能会有点帮助,效果如下:
就是以上效果,废话不多说,上代码
wxml:
<view class='list_box' wx:for='{{list}}' wx:key='this' wx:for-item='parentItem' wx:for-index='parentIndex' >
<view class='list'>
<view class='list_name_box' catchtap='listTap' data-parentindex='{{parentIndex}}'>
<text class='list_item_name'>{{parentItemlistName}}</text>
<image src='/img/downpng' class='icon_down {{parentItemshow&&"icon_down_rotate"}}'></image>
</view>
<view class='list_item_box' wx:if='{{parentItemshow}}'>
<view class='list_item' wx:for='{{parentItemitem}}' wx:key='this' catchtap='listItemTap' data-index='{{index}}' data-parentindex='{{parentIndex}}'>
<view class='list_item_name_box'>
<text class='list_item_name'>{{itemitemName}}</text>
<image src='/img/downpng' class='icon_down {{itemshow&&"icon_down_rotate"}}'></image>
</view>
<view class='other_box' wx:if='{{itemshow}}'>
<view class='other'>
<text class='other_title'>内容:</text>
<text class='other_text'>{{itemcontent}}</text>
</view>
<view class='other'>
<text class='other_title'>时间:</text>
<text class='other_text'>{{itemtime}}</text>
</view>
</view>
</view>
</view>
</view></view>
然后wxss:

注意:此处实现采用的是无APPID的开发模式,实际应用应该在微信小程序管理平台的开发设置中配置合法域名。

步骤
字体文件转化成base64格式
解压压缩包 —- 找到ttf格式文件 —- 上传到平台转化为base64格式 —- 下载压缩包 —- 将css文件名改为wxss —- 放入项目文件夹 —- 用@import全局引入 —- 使用
使用—-引入及全局定义
123456789101112131415161718192021222324@import "src/css/iconwxss";iconfont { font-family: "iconfont"; font-size:60rpx;}/本项目使用的18个图标 /icon-zhiding:before{content: '\e739';}icon-zuojiantou:before{content: '\e736';}icon-youjiantou:before{content: '\e735';}icon-shangjiantou:before{content: '\e734';}icon-xiajiantou1:before{content: '\e733';}icon-xiajiantou:before{content: '\e6cc';}icon-gengduotianchong:before{content: '\e67f';}icon-erweima:before{content: '\e65f';}icon-fenleiorguangchangorqita:before{content: '\e64f';}icon-dibiao:before{content: '\e64d';}icon-bangzhu:before{content: '\e64a';}icon-xinfeng:before{content: '\e640';}icon-duihuaxinxi:before{content: '\e639';}icon-sousuo:before{content: '\e62f';}icon-shouye:before{content: '\e62d';}icon-shezhi:before{content: '\e62a';}icon-shanchu:before{content: '\e629';}icon-dianhua:before{content: '\e61b';}开发使用

appjson文件面看自tabBar写
"tabBar":{
"selectedColor": "#3cc51f",
"list":[{
"pagePath":"pages/index/index",
"iconPath":"images/icon_homepng",
"selectedIconPath":"images/icon_home_selectedpng",
"text":"主页"
},{
"pagePath":"pages/car/index",
"iconPath":"images/icon_homepng",
"selectedIconPath":"images/icon_home_selectedpng",
"text":"购物车"
},{
"pagePath":"pages/member/index/index",
"iconPath":"images/icon_memberpng",
"selectedIconPath":"images/icon_member_selectedpng",
"text":"员"
},{
"pagePath":"pages/store/index/index",
"iconPath":"images/20170811112822png",
"selectedIconPath":"images/20170811113017png",
"text":"商家"
}]
}
我知道设置5少没留意 能设置太少吧 设置几试试
iconList是你在js中data定义的一个数组么?问题请详细描述下。
iconListpush()// 为数组添加元素的内容thissetData({
iconList: iconList
})
