请问小程序中的点赞数字为啥不能正常显示?
插件名称:小程序DEMO
我复制过来的show.js
调用的时候也是{{supports}}
但是不懂为什么,默认加载的时候,数据都显示为0,不会显示正确的点赞数,只有点击了这个按钮,增加或者减少了点赞次数,这个点赞次数才会正确。
是自定义回调那边没输出好吗?自定义回调那边没写,我看了下JSON数据,点赞数是NULL
show.wxml
<view class="l_lbdz l_lbliuc fl" bindtap="up"> <view class="l_lbliu l_lbliub"> <image mode="widthFix" src="{{upsImg}}"></image> </view> <view class="l_lbliubc">{{supports}}</view> </view>
show.js
var WxParse = require('../../wxParse/wxParse.js'); var app = getApp(); var http_url = app.globalData.http_api + "s=anli&c=show"; http_url += '&api_call_function=anli_show_data'; var member_url = app.globalData.http_api + "s=api&app=anli&c=module&api_auth_code=" + wx.getStorageSync('member_auth') + "&api_auth_uid=" + wx.getStorageSync('member_uid'); Page({ data: { id: '', content: '', supports: 0, upsImg: "../../images/xqb.png", collectImg: "../../icons/collect.png", }, onLoad: function (options) { app.showModel(); var self = this; wx.request({ url: http_url, data: { id: options.id }, header: { 'content-type': 'application/json' }, dataType: 'json', method: 'GET', success: function (res) { if (res.data.code == 1) { // 是否收藏 wx.request({ url: member_url + '&m=is_favorite', data: { id: options.id }, header: { 'content-type': 'application/json' }, dataType: 'json', method: 'GET', success: function (sc) { if (sc.data.code == 1) { self.setData( { collectImg: "../../icons/collect-active.png", }) } } }); // 格式化文章内容 var article = res.data.data.content; WxParse.wxParse('data', 'html', article, self); self.setData({ content: res.data.data, supports: res.data.data.support, id: options.id }) wx.hideToast(); } else { wx.showModal({ showCancel: false, content: res.data.msg }) } } }) }, up: function () {//点赞 var self = this; wx.request({ url: member_url + '&m=digg&value=1', data: { id: self.data.id }, header: { 'content-type': 'application/json' }, dataType: 'json', method: 'GET', success: function (sc) { if (sc.data.code == 1) { wx.showToast({ icon: 'success', title: sc.data.msg, duration: 2000 }); self.setData( { supports: sc.data.data, }) } else { wx.showModal({ showCancel: false, content: sc.data.msg }) } } }); } })
后台自定义回调
直接访问API,得到了NULL空值
