三国志14信息查询小程序（历史武将信息一览）制作更新过程03-主要页面的设计-编程知识

1，小程序的默认显示

在这里插入图片描述
分为三部分，头部的标题、中间的内容区和底部的标签栏。点击标签可以切换不同页面，这是在app.json文件中配置的。代码如下：

//所有用到的页面都需要在 pages 数组中列出，否则小程序可能会出现错误或无法正确加载。
//首页的页面路径放在这个数组的第一个位置。例如，将 pages/index/index 设置为首页。
{"pages": ["pages/index/index","pages/details/details","pages/my/details","pages/about/about"],"subpackages": [],//标题文本设置"window": {"backgroundTextStyle": "light","navigationBarBackgroundColor": "#461311","navigationBarTitleText": "三国志14","navigationBarTextStyle": "white"},//标签，表示小程序的主要功能或页面，用户可以点击切换。"tabBar": {"color": "#bfc1ab","selectedColor": "#13b11c","backgroundColor": "#381B25","list": [{"pagePath": "pages/index/index","iconPath": "image/icon_component.png","selectedIconPath": "image/icon_component_HL.png","text": "武将数据"},{"pagePath": "pages/my/details","iconPath": "image/icon_map.png","selectedIconPath": "image/icon_map_HL.png","text": "综合信息"},{"pagePath": "pages/about/about","iconPath": "image/icon_about.png","selectedIconPath": "image/icon_about_HL.png","text": "关于"}]},"sitemapLocation": "sitemap.json","permission": {"scope.userLocation": {"desc": "获取位置，方便按区域分配 "}}
}

2，武将信息页

在这里插入图片描述
分为三部分，查询工具栏、表头及数据列表
这是数据列表的代码：

 <!-- 数据列表 --><view wx:for="{{goodsList}}" wx:key="index" class="table"><view class="tr bg-g" bindtap="onGoodsDetail" data-all="{{item}}" data-name="{{item.name}}"><view class="td">{{item.name}}</view><view class="td">{{item.tongshuai}}</view><view class="td">{{item.wuli}}</view><view class="td">{{item.zhili}}</view><view class="td">{{item.zhengzhi}}</view><view class="td">{{item.meili}}</view></view></view>

可以看到，数据goodsList以循环的形式显示，每行数据上加入了点击事件onGoodsDetail，即跳转到人物详情页。
再看一下js里的方法：

（1）在页面加载时获取数据

 onLoad: function (options) {// 调用获取列表数据的方法this.getGoodsList(true)},

（2）获取数据方法：

  //获取列表数据并赋值给goodsListgetGoodsList(reachBottom) {...wx.request({url: url_get,//你的后台url地址data: {order: this.data.order,key: this.data.key,page: this.data.queryObj.pagenum,intPageSize: this.data.queryObj.pagesize,},header: {'content-type': 'application/x-www-form-urlencoded'},method: "GET",success(result) {if (reachBottom) {that.setData({goodsList: [...that.data.goodsList, ...result.data.response.data],total: result.data.response.dataCount,})}},fail(error) {console.log('request fail', error);},// 无论获取数据是否成功都会执行该方法complete: () => {wx.hideLoading() // 关闭loadingthis.setData({isLoading: false})}})}

查询，排序也是在改变条件后执行getGoodsList方法。

（3）稍微需要说明的是页面上拉获取数据的方法：

 /*** 页面上拉触底事件的处理函数*/onReachBottom: function () {// 判断是否还有下一页数据if (this.data.queryObj.pagenum * this.data.queryObj.pagesize >= this.data.total) {wx.showLoading({title: '数据加载完毕！',})wx.hideLoading() // 关闭loadingreturn}// 判断是否正在请求其它数据，如果是，则不发起额外的请求if (this.data.isLoading) returnlet pagenum = this.data.queryObj.pagenumthis.setData({queryObj: {pagenum: pagenum += 1// 让页码值自增 +1}})this.getGoodsList(true)// 重新获取列表数据},

（4）及点击跳转到武将武将详情页的方法

 // 点击详情onGoodsDetail: function (e) {var name = e.currentTarget.dataset.namevar data = JSON.stringify(e.currentTarget.dataset)wx.navigateTo({url: '../details/details?name=' + name + '&data=' + data})},

3，综合信息页

在这里插入图片描述
这个页面没有什么好说的，一个个内容摆下来就是了，很多不知道放在哪里的东西都先放在这里了。

4，关于页

与综合信息页结构相同

评论评分的页面代码：
wxml文件：

<!-- components/star-rating/star-rating.wxml -->
<view >
<!-- 人物总评分 --><view class="star-rating-center">{{initialName}}：<block wx:for="{{stars_total}}" wx:key="index"><text class="star {{item.selected ? 'selected' : ''}}" data-index="{{index}}">{{item.type}}</text></block>[{{goal}}分]
</view>
<!-- 评分&评论 --><view class="reviews-container"><block wx:for="{{ratingsAndComments}}" wx:key="index" ><view class="single-review"><!-- 这里添加显示单个评分的代码 --><view class="star-container"><block wx:for="{{item.stars}}" wx:key="index"><text class="star {{item.selected ? 'selected' : ''}}" data-index="{{index}}">{{item.type}}</text></block><!-- <view style=" justify-content: center;align-items: center;margin-left;20rpx;margin-top:15rpx">{{item.createTime}}</view> --></view><!-- 评论 --><text class="comment">{{item.comment}}</text></view></block></view>
</view>
<!-- 评分提交 -->
<view class="rating-editor"><!-- 评分 -->
<view class="flex-container"><text class="label">评分：</text><view class="star-container-editor"><block wx:for="{{stars}}" wx:key="index"><text class="star {{item.selected ? 'selected' : ''}}" bindtap="onStarClick" data-index="{{index}}">{{item.type}}</text></block></view>
</view><!-- 评论 -->
<view class="flex-container"><text class="label">评论：</text><view class="textarea-container"><textarea style="height:100rpx" type="text" name="biography" value="{{biography}}" placeholder="" maxlength="5000" bindinput="onTextareaInput"></textarea></view>
</view><button class="submit-button" bindtap="onSubmitRating">提交评分</button>
</view>
