}
效果

4.数据绑定
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

<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);
},
})
5.wx-for循环新闻列表
列表渲染文档

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

  <text class='post-title'>{{item.title}}</text>
  <image class='post-image' src='{{item.post_img}}'></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.collect_num}}</text>
    <image class='post-like-image' src='../../images/icon/view.png'></image>
    <text class='post-like-font'>{{item.view_num}}</text>   
  </view> 
</view>

</block>
</view>
6.小程序事件机制
事件文档

路由文档

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',
})
}
}
)
7.小程序的模块化
列表渲染

模块化

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

  <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
// });
}
})
8.template模板的使用
模板

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

  <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

<block wx:for="{{postlist}}" wx:for-item="item">
<template is="postItem" data="{{...item}}" />
</block>
</view>
post-item-template.wxss创建模板

.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;

}

.post-image{
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;
}
