小程序实现订单评价和商家评价
小程序做线上商城就离不开交互,包括最重要的支付和订单评价系统。订单评价简单的只有商品评价,比较齐全的是商品和商家一起评价。
本文介绍的目录包含,商品评价,商家评价,星级评分,上传照片,以及评论字数限制。
目录:
(一)星级评分的写法
(二)评论区的字数显示和限制
(三)图片张数限制和上传到服务器
(四)完整代码
看看开发工具中的样品图:
在评论页中展示商品和商家两栏的评价内容,并且提交评价的时候也要区分开,将商品和商家的评论内容用数组的形式提交。
注意array和[object,object]的数据格式。
先说逻辑,因为两块其实是同一个功能,只不过是把方法名字区分为A和B,A和B的函数内容一样的,只有数据内容不一样。
所以这里是只讲A方法。
(一)先说星级评分方法;
<view class='stars'> <view class='text'>评分</view> <view class='star_list'> <block wx:for="{{stars}}" wx:key> <image class="star-image" name="defen" value="{{key}}" style="left: {{item*30}}rpx" src="{{key > item ?(key-item == 0?normalSrc:selectedSrc) : normalSrc}}"> <view class="item" style="left:0rpx" data-key="{{item+1}}" bindtap="selectRight"></view> </image> </block> </view> </view>
用数组来存储图片,wx:for来循环图片列表,五星,列表长度就是0-4总共5,10星则是0-9。
两张图片。一张是带颜色的作为点亮状态,一张是默认的作为默认状态。设置选中函数selectRight。点星星一次则将星星图片的位置从left位移多少个单位到点击的对应位置。反之则取消对应的星星选中。
函数:
//点击右边递增,否则递减,评分,商品+商家B selectRight (e) { var key = e.currentTarget.dataset.key; //评分 if (this.data.key == 1 && e.currentTarget.dataset.key == 1) { //只有一颗星的时候,再次点击,变为0颗 key = 0; } this.setData({ key: key }) },
(二)评论区的字数显示和限制。
方法,给textarea一个最大的length.max-length =300.然后给输入域一个获取输入的事件,bindInput。通过获取bindInput的value长度,来限制。
<view class='textarea'> <textarea id='advice' name="advice" type="text" maxlength="{{max}}" bindinput="inputs" value="{{advice}}" placeholder="请输入评价内容..." placeholder-class='p_s'></textarea> <view class='fontNum'>{{fontNum}}</view> </view>
JS中通过最大长度与输入长度的减法来动态改变fontNum剩余字数。
//字数限制 商品+商家B inputs (e) { var value = e.detail.value, len = parseInt(value.length); //最多字数限制 if (len > this.data.max) return; this.setData({ fontNum: 300-len //当前字数 }); },
(三)上传多张图片并发送到服务器
默认的API即可,但是图片地址需要转化。wx.chooseImage所给出的图片地址是本地,并没有存到服务器上,还需要保存到服务器上。
使用wx.request的方法。在回调的结果中,取出地址链接,存为数组或者单个url信息。与其他内容一起进行表单提交。
$uploadFile({ filePath: tempFilePaths[0], formData: { evaluateType: 'store' }, name: 'evaluteImage', url: 'v4/shop/file/uploadBySmall' }).then((res) => { if (res.isSuccess) { let url = res.resultData that.setData({ imgboxB: [url], imgboxB: imgboxB, }) //$toast('图片上传成功') } else { //$toast(res.message) } })
