Uparse插件导致的noData: { type: String, default: '<div style="color: red;">数据不能为空</div>' },改为 noData: { type: String, default: '' },
在hbuilderx里运行编译uni-app的微信小程序版,报:enable ide service (y/n) [27d [27c解决方法:在微信开发者工具里点击设置》安全设置,开启服务端口
解决方法如下图:
解决办法如下图:
1.pages.json中开启触底距离"onReachBottomDistance":{ "pages": [ //pages数组中第一项表示应用启动页,参考:https://uniapp.dcloud.io/collocation/pages { "path": "pages/index/index", "style": { "navigationBarTitleText": "uni-app", "enablePullDownRefresh": true, ..
uni.request({ url: 'https://www.example.com/request', //仅为示例,并非真实接口地址。 data: { text: 'uni.request' }, header: { 'custom-header': 'hello' //自定义请求头信息 }, success: (res) => { console.log(res.data); th.
添加placeholder-style属性,如下<input class="uni-input" placeholder="输入单号查看物流信息" placeholder-style="font-size:26rpx;color:#ACACAC;" type="text">
原因:swiper-item不能加行内样式可在下一级加view加行内样式
修改unpackage/dist/dev/mp-weixin/project.config.json"checkSiteMap": false,
html <view>搜索日期:</view> <view> {{defaultStartTime}}<image @click="selStart" class="ssel-icon" src="/static/images/ssel.png"></image> <u-picker mode="time" :defaultTime="defaultStartTime" v
HBuilderX创建的项目1.勾选运行-->运行到小程序模拟器2.勾选运行->运行时是否压缩代码cli创建的项目在pacakge.json中添加参数--minimize,示例:"dev:mp-weixin": "cross-env NODE_ENV=development UNI_PLATFORM=mp-weixin vue-cli-service uni-build --watch --minimize"...
注意事项,后端API返回的一定要是HTML形式的, 富文本编辑器存入数据的内容,则需要转化,如果是php,则用下面的函数进行转化htmlspecialchars_decode()1.导入到项目中2.修改页面<template> <div> <u-parse :content="article" @preview="preview" @navigate="navigate" /> </div></template.
解决办法:加key属性<view class="shenbao-cont" v-for="(item, index) in listitem" :key="index"></view>
<template> <view> <view :class="status == 1? 'before-style': 'after-style'" @tap="getVerifyCode" >{{tips}}</view> <u-toast ref="uToast"></u-toast> <u-verification-code start-text="发送验证码" change-text="Xs" :seco.
<template> <view> <view class="item-box" v-for="(item, index) in list"> <input type="text" placeholder="请输入"> <button type="warning" @click="delItem(item)">删除</button> </view> <button type="primary.
方法一:pages/pre/pre.vue<template> <view> <view>返回的数据为:</view> <view>id: {{testdata.id}}</view> <view>name: {{testdata.name}}</view> <button type="primary" @click="goNext">跳转到下一页面</button&
<view class="sticky-top"> <u-tabs @change="changePackStatus" height="84" font-size="28" name="cate_name" bar-width="60" bar-height="4" active-color="#EB9309" count="cate_count" :list="list" :is-scroll="false" :current="current"></u...
copyCode(value) { uni.setClipboardData({ data: value, success: () => { uni.showToast({ title: "复制成功" }) } }); },
订单状态 == 值 ?'样式1':'样式2'<view :class=" 4 == 12 ? 'order-question': 'order-status'"> 交易成功 </view>
<template> <view> <button data-index="11" type="primary" @click="clickBtn(1, $event)">点击事件1</button> <button data-index="22" type="primary" @click="clickBtn(2, $event)">点击事件2</button> </view></template&g.
计算属性:可以理解为是对data中的数据提供了一种加工或过滤的能力<template> <view> <view v-for="item in filterList" :key="item.id" > {{item.name}} </view> <!-- <view v-for="item in porcessList" :key="item.id" > {{item.name}} --&g
通过v-if来决定显示和隐藏,不适合做频繁的切换显示通过v-show来决定显示和隐藏,适合做频繁的切换和显示<view v-if="true">显示</view><view v-if="false">隐藏</view><view v-if="isShow">显示或隐藏</view><view v-show="true">显示</view><view v-show="false">隐藏

<template> <view class="goods-list"> <goods-list :goods="goods" @goodsItemClick="goGoodsDetail"></goods-list> <view>我是有底线的</view> </view></template><script> import goodsList from '../../compon.
<template> <view class="goods-list"> <goods-list :goods="goods"></goods-list> <view>我是有底线的</view> </view></template><script> import goodsList from '../../components/goods-list/goods-list.vue'.
1.根目录下创建utils/api.jsconst BASE_URL = 'http://localhost:8082'export const myRequest = (options)=>{ return newPromise((resolve, reject)=>{ uni.request({ url: BASE_URL+options.url, method: options.method || 'GET', data: optionds.data ||
uni.$emit(eventName,OBJECT)触发全局的自定事件uni.$on(eventName,callback)监听全局的自定义事件。事件可以由 uni.$emit 触发,回调函数会接收所有传入事件触发函数的额外参数。<template> <view> <button type="primary" @click="addNum">这是A组件</button> </view></template>
父组件传子组件:父组件定义值,子组件通过props获取,然后渲染子组件传父组件:子组件中用$emit方法,父组件用获取子组件:<template> <view> <button type="primary" @click="sendNum">{{title}}这是test组件,</button> </view></template><script> export default {
