小程序?qū)崿F(xiàn)頁面多級來回切換的示例代碼

第小程序?qū)崿F(xiàn)頁面多級來回切換的示例代碼目錄第一步第二步全部完整代碼wxmljscss

第一步

首先通過swiper創(chuàng)建一個簡單的多tab頁面

通過觸發(fā)pagechange1方法中的事件對currentIndex來進(jìn)行賦值，又通過currentIndex的改變使前端wxml對應(yīng)更改，這個部分對滑動和點(diǎn)擊的操作都一樣，無非就是使currentIndex對應(yīng)到各自的位置，通過數(shù)字來決定位置

//滑動

pagechange1:function(ee){

if("touch"===ee.detail.source){

letcurrentPageIndex=this.data.currentIndex;

currentPageIndex=(currentPageIndex+1)%2;

this.setData({

currentIndex:currentPageIndex,

//點(diǎn)擊tab時(shí)觸發(fā)

titleClick:function(e){

this.setData({

//拿到當(dāng)前索引并動態(tài)改變

currentIndex:e.currentTarget.dataset.idx

這個部分完整代碼如下：

wxml

view

!--Tab布局--

view

viewbindtap='titleClick'data-idx='0'

textclass="{{0==currentIndex'fontColorBox':''}}"安卓/text

hrclass="{{0==currentIndex'lineBox':'notLineBox'}}"/

/view

viewbindtap='titleClick'data-idx='1'

textclass="{{1==currentIndex'fontColorBox1':''}}"蘋果/text

hrclass="{{1==currentIndex'lineBox':'notLineBox'}}"/

/view

color:black;

.navBox{

height:108rpx;

display:flex;

padding-left:20%;

font-size:30rpx;

display:flex;

flex-direction:column;

align-items:center;

.lineBox,.notLineBox{

/*底部內(nèi)容樣式*/

height:100vh;

overflow:scroll;

margin:12rpx0rpx;

background:white;

font-size:28rpx;

js

constapp=getApp()

Page({

data:{

currentIndex:0,//默認(rèn)第一個

pagechange1:function(ee){

if("touch"===ee.detail.source){

letcurrentPageIndex=this.data.currentIndex;

currentPageIndex=(currentPageIndex+1)%2;

this.setData({

currentIndex:currentPageIndex,

//點(diǎn)擊tab時(shí)觸發(fā)

titleClick:function(e){

this.setData({

//拿到當(dāng)前索引并動態(tài)改變

currentIndex:e.currentTarget.dataset.idx

第二步

上一步完成后，下級頁面再加一個滑動頁面，當(dāng)內(nèi)切換結(jié)束后，在做切換就是父級的切換操作

在內(nèi)容1的view中寫入代碼即可，由于父級代碼只能是小于2個頁面才有效，所以我們不用父級的這個滑動來做子滑動，不僅僅是因?yàn)閎ug的問題，這樣也避免了樣式和數(shù)據(jù)重復(fù)的問題

在這里我們插入wxml代碼：

view

scroll-viewscroll-x="true"scroll-left="{{scrollLeft}}"

viewclass="tab-item{{currentTab==0'active':''}}"data-current="0"bindtap="swichNav"熱門/view

viewclass="tab-item{{currentTab==1'active':''}}"data-current="1"bindtap="swichNav"影音/view

viewclass="tab-item{{currentTab==2'active':''}}"data-current="2"bindtap="swichNav"閱讀/view

viewclass="tab-item{{currentTab==3'active':''}}"data-current="3"bindtap="swichNav"游戲/view

viewclass="tab-item{{currentTab==4'active':''}}"data-current="4"bindtap="swichNav"福利/view
