真正的数据肯定不可能像上面那样写在wxml文件里面,而是从服务器加载的数据,下面模拟从服务器加载数据。
post.wxml
<view class='post-container'>
<view class='post-author-date'>
<image class='post-author' src="{{author_img}}"></image>
<text class='post-date'>{{date}}</text>
</view>
<text class='post-title'>{{title}}</text>
<image class='post-image' src='{{post_img}}'></image>
<text class='post-content'>{{content}}</text>
<view class='post-like'>
<image class='post-like-image' src='../../images/icon/chat.png'></image>
<text class='post-like-font'>{{collect_num}}</text>
<image class='post-like-image' src='../../images/icon/view.png'></image>
<text class='post-like-font'>{{view_num}}</text>
</view>
</view>
post.js
Page({
/**
* 页面的初始数据
*/
data: {
},
/**
* 生命周期函数--监听页面加载
*/
onLoad: function (options) {
var post_content1={
date:"2018/8/16",
title:"荷塘月色",
post_img: '/images/post/crab.png',
content:'这几天心里颇不宁静。今晚在院子里坐着乘凉,忽然想起日日走过的荷塘,在这满月的光里,总该另有一番样子吧。',
view_num:"100",
collect_num:'50',
author_img:'/images/avatar/1.png'
}
this.setData(post_content1);
},
})
假设有两篇新闻,通过wx:for列表循环展示新闻信息。
post.js
Page({
/**
* 页面的初始数据
*/
data: {
},
/**
* 生命周期函数--监听页面加载
*/
onLoad: function (options) {
var posts_content = [
{
date: "2018/8/16",
title: "荷塘月色",
post_img: '/images/post/crab.png',
content: '这几天心里颇不宁静。今晚在院子里坐着乘凉,忽然想起日日走过的荷塘,在这满月的光里,总该另有一番样子吧。',
view_num: "100",
collect_num: '50',
author_img: '/images/avatar/1.png'
},
{
date: "2018/7/15",
title: "背影",
post_img: '/images/post/bl.png',
content: '我与父亲不相见已二年余了,我最不能忘记的是他的背影 。那年冬天,祖母死了,父憨穿封费莩渡凤杀脯辑亲的差使也交卸了,正是祸不单行的日子',
view_num: "120",
collect_num: '150',
author_img: '/images/avatar/2.png'
}
]
this.setData({
posts_key: posts_content
});
},
})
post.wxml
<view>

<swiper-item><image src='/images/post/xiaolong.jpg' ></image></swiper-item>
<swiper-item><image src='/images/post/vr.png' ></image></swiper-item>
</swiper>
<block wx:for="{{posts_key}}" wx:for-item="item">
<view class='post-container'>
<view class='post-author-date'>
<image class='post-author' src="{{item.author_img}}"></image>
<text class='post-date'>{{item.date}}</text>
</view>
<text class='post-title'>{{item.title}}</text>
<image class='post-image' src='{{item.post_img}}'></image>

<text class='post-like-font'>{{item.view_num}}</text>
</view>
</view>
</block>
</view>
实现从首页跳转到新闻列表页
welcome.wxml绑定一个事件
<view class='container'>
<image class='user-avatar' src="/images/avatar/4.png"></image>
<text class='user-name'><text style='color:blue'>Hello</text>,八月</text>
<view class='moto-container' bindtap='onTap'>
<text class='moto'>开启小程序之旅</text>
</view>
</view>
welcome.js
Page({
onTap:function(){
wx.redirectTo({
url: '../posts/post',
})
}
}
)
将业务中的数据分离到单独的数据文件
创建data文件夹,再创建postsdata.js
post.wxml
修改地方:wx:for="{{postlist}}",还有一些变量
<block wx:for="{{postlist}}" wx:for-item="item">
<view class='post-container'>
<view class='post-author-date'>
<image class='post-author' src="{{item.avatar}}"></image>
<text class='post-date'>{{item.date}}</text>
</view>
<text class='post-title'>{{item.title}}</text>
<image class='post-image' src='{{item.imgSrc}}'></image>
<text class='post-content'>{{item.content}}</text>
<view class='post-like'>
<image class='post-like-image' src='../../images/icon/chat.png'></image>
<text class='post-like-font'>{{item.collection}}</text>
<image class='post-like-image' src='../../images/icon/view.png'></image>
<text class='post-like-font'>{{item.reading}}</text>
</view>
</view>
</block>
postsdata.js
把文章分离出来。通过 module.exports 对外暴露接口。
var local_database = [{
date: "2018/8/16",
title: "荷塘月色",
imgSrc: '/images/post/crab.png',
content: '这几天心里颇不宁静。今晚在院子里坐着乘凉,忽然想起日日走过的荷塘,在这满月的光里,总该另有一番样子吧。',
reading: "100",
collection: '50',
avatar: '/images/avatar/1.png'
},
{
date: "2018/7/15",
title: "背影",
imgSrc: '/images/post/bl.png',
content: '我与父亲不相见已二年余了,我最不能忘记的是他的背影 。那年冬天,祖母死了,父憨穿封费莩渡凤杀脯辑亲的差使也交卸了,正是祸不单行的日子',
reading: "120",
collection: '150',
avatar: '/images/avatar/2.png'
},
{
date: "2018/6/2",
title: "济南的冬天",
imgSrc: '/images/post/vr.png',
content: '对于一个在北平住惯的人,像我,冬天要是不刮风,便觉得是奇迹;济南的冬天是没有风声的。',
reading: "80",
collection: '50',
avatar: '/images/avatar/3.png'
},
{
date: "2018/5/1",
title: "江南之雨",
imgSrc: '/images/post/cat.png',
content: '江南之春雨如此缠绵,然煽情,如此醉,影青青之烟雨巷,雨丝风,润之使人动心如此',
reading: "80",
collection: '50',
avatar: '/images/avatar/3.png'
},
{
date: "2018/4/6",
title: "忆江南",
imgSrc: '/images/post/xiaolong.jpg',
content: '昨晚和阿浩谈起诸多童年记忆,不知不觉眼前浮现一片油菜花海,黄灿灿,一眼望不到头,连空气都带着甜香。',
reading: "80",
collection: '50',
avatar: '/images/avatar/4.png'
},
]
module.exports = {
postlist:local_database
}
post.js使用 require(path) 将代码引入
var postsData = require('../../data/posts-data.js')
Page({
data: {
postlist: postsData.postlist
},
onLoad: function(options) {
// this.setData({
// posts_key: postsData.postlist
// });
}
})
在posts目录下创建模板目录post-item目录,然后分别创建post-item-template.wxml和post-item-template.wxss
post-item-template.wxml创建模板
<template name="postItem">
<view class='post-container'>
<view class='post-author-date'>
<image class='post-author' src="{{avatar}}"></image>
<text class='post-date'>{{item.date}}</text>
</view>
<text class='post-title'>{{title}}</text>
<image class='post-image' src='{{imgSrc}}'></image>
<text class='post-content'>{{content}}</text>
<view class='post-like'>
<image class='post-like-image' src='../../images/icon/chat.png'></image>
<text class='post-like-font'>{{collection}}</text>
<image class='post-like-image' src='../../images/icon/view.png'></image>
<text class='post-like-font'>{{reading}}</text>
</view>
</view>
</template>
post.wxml使用模板
<import src='post-item/post-item-template.wxml' />
<view>
<swiper indicator-dots='true' autoplay='true' interval='2000'>
<swiper-item>
<image src='/images/post/bl.png'></image>
</swiper-item>
<swiper-item>
<image src='/images/post/xiaolong.jpg'></image>
</swiper-item>
<swiper-item>
<image src='/images/post/vr.png'></image>
</swiper-item>
</swiper>
<block wx:for="{{postlist}}" wx:for-item="item">
<template is="postItem" data="{{...item}}" />
</block>
</view>
post-item-template.wxss创建模板
.post-container{
display: flex;
flex-direction: column;
margin-top:20rpx;
margin-bottom: 40rpx;
background-color: #fff;
border-top:1px solid #ededed;
border-bottom: 1px solid #ededed;
padding-bottom: 5px;
}
.post-author-date{
margin:10rpx 0 20rpx 10rpx
}
.post-author{
width: 60rpx;
height: 60rpx;
vertical-align: middle;
}
.post-date{
margin-left: 20rpx;
vertical-align: middle;
margin-bottom: 5px;
font-size: 26rpx;
}
.post-title{
font-size: 34rpx;
font-weight: 600;
color:#333;
margin-bottom: 10px;
margin-left: 10px;
}

margin-left: 16px;
width: 100%;
height: 340rpx;
margin:auto 0;
margin-bottom: 15px;
}
.post-content{
color:#666;
font-size: 28rpx;
margin-bottom:20rpx;
margin-left: 20rpx;
letter-spacing: 2rpx;
line-height: 40rpx;
}
.post-like{
font-size: 13px;
flex-direction: row;
line-height: 16px;
margin-left: 10px;
}
.post-like-image{
height: 16px;
width:16px;
margin-right: 8px;
vertical-align: middle;
}
.post-like-font{
vertical-align: middle;
margin-right: 20px;
}
post.wxss使用模板
@import "post-item/post-item-template.wxss"
swiper{
width:100%;
height:500rpx;
}
标签:flex 正是 100% load 忘记 pat .post tps png
