对于微信事件,不多说,自己看文档https://mp.weixin.qq.com/debug/wxadoc/dev/framework/view/wxml/event.html?t=20161122
效果
首先,注意一下微信小程序事件触发顺序
单击 | touchstart → touchend → tap |
双击 | touchstart → touchend → tap → touchstart → touchend → tap |
长按 | touchstart → longtap → touchend → tap |
看到没 所有的点击事件必然会触发tap - - Are you kidding me ?
所有的都有tap 那还有个毛线的用- - 可能我比较菜没有悟到其中奥秘 Orz
解决长按,其实方法很简单,提供两种思路吧
1. 触发longtap时加锁,手指移开屏幕时解除锁
2. 通过触发事件来控制事件分发
那么~ 简单粗暴,看代码
wxml:
- <scroll-view class="position_common_info" scroll-y="true">
- <view class="line" style="margin-top:30rpx;">
- </view>
- <view wx:for="{{common_position}}" bindtouchstart="mytouchstart" bindtouchend="mytouchend" bindtap="editAddress" data-name="{{item.name}}" data-positionId="{{item.positionId}}" data-gendar="{{item.gendar}}" data-contactTel="{{item.contactTel}}" data-addressName="{{item.addressName}}"
- data-customerDesc="{{item.customerDesc}}" data-city="{{item.city}}" data-uid="{{item.uid}}" data-addressAddr="{{item.addressAddr}}" data-positionId="{{item.positionId}}">
- <!--<navigator url="/pages/order/address/add_address/add_address?name={{item.name}}
- &gendar={{item.gendar}}&contactTel={{item.contactTel}}&addressName={{item.addressName}}
- &customerDesc={{item.customerDesc}}&city={{item.city}}&uid={{item.uid}}
- &addressAddr={{item.addressAddr}}&positionId={{item.positionId}}">-->
- <view class="address_text">
- <text class="name">{{item.name}}</text>
- <text class="name" wx:if="{{item.gendar==‘1‘}}">先生</text>
- <text class="name" wx:else>女士</text>
- <text class="tel">{{item.contactTel}}</text>
- <view class="address">{{item.addressName}}</view>
- </view>
- <image class="icon_edit" src="{{imgUrls_edit_original}}"></image>
- <view class="lines"></view>
- <!--</navigator>-->
- </view>
- </scroll-view>
- <navigator class="btn" url="{{page_edit}}"> 新增</navigator>
主要看
<view wx:for="{{common_position}}" bindtouchstart="mytouchstart" bindtouchend="mytouchend" bindtap="editAddress" >
其他都是连带数据- - 完全可以无视
最最最重要的wxjs即将来临,噔噔噔噔~
- editAddress: function (event) {
- let that = this;
- //触摸时间距离页面打开的毫秒数
- var touchTime = that.data.touch_end - that.data.touch_start;
- console.log(touchTime);
- //如果按下时间大于350为长按
- if (touchTime > 350) {
- wx.showModal({
- title: ‘提示‘,
- content: ‘是否删除该地址‘,
- success: function (res) {
- if (res.confirm) {
- app.func.req(‘delUserPosition?tel=‘ + ‘13999999999‘ + ‘&positionId=‘ + event.currentTarget.dataset.positionid, function (res) {
- if (res.data.result == ‘false‘) {
- console.log(res.data.msg);
- wx.showToast({
- title: res.data.msg,
- icon: ‘success‘,
- duration: 2000
- })
- } else {
- that.loadData();
- }
- }, function (res) {
- console.log(res.data);
- });
- }
- }
- })
- } else {
- wx.navigateTo({
- url: ‘/pages/order/address/add_address/add_address?name=‘ + event.currentTarget.dataset.name
- + ‘&gendar=‘ + event.currentTarget.dataset.gendar
- + ‘&contactTel=‘ + event.currentTarget.dataset.contacttel
- + ‘&addressName=‘ + event.currentTarget.dataset.addressname
- + ‘&customerDesc=‘ + event.currentTarget.dataset.customerdesc
- + ‘&city=‘ + event.currentTarget.dataset.city
- + ‘&uid=‘ + event.currentTarget.dataset.uid
- + ‘&addressAddr=‘ + event.currentTarget.dataset.addressaddr
- + ‘&positionId=‘ + event.currentTarget.dataset.positionid,
- })
- }
- },
- //按下事件开始
- mytouchstart: function (e) {
- let that = this;
- that.setData({
- touch_start: e.timeStamp
- })
- console.log(e.timeStamp + ‘- touch-start‘)
- },
- //按下事件结束
- mytouchend: function (e) {
- let that = this;
- that.setData({
- touch_end: e.timeStamp
- })
- console.log(e.timeStamp + ‘- touch-end‘)
- },
代码都有备注,自己体会吧
