一、前期准備工作
軟件環境:微信開發者工具
官方下載地址:https://mp.weixin.qq.com/debug/wxadoc/dev/devtools/download.html
1、基本需求。
- 實現用戶自定義底部導航
2、案例目錄結構
二、程序實現具體步驟
1.自定義nav.wxml代碼
<template name="nav">
<view class="nav_link" bindtap="{{fn}}">
<button class="defalut_btn {{current== 0 ? '' : 'on_cor'}}">
<block wx:if="{{style == 0}}">
<icon class="iconfont {{ico}} del_ico idx_ico"></icon>
<text class="txt">{{name}}</text>
</block>
<block wx:if="{{style == 1}}">
<view class="plus_wp">
<image src='../../images/plus_ico.png' class="plus_ico" />
</view>
<text class="txt txt_fb">{{name}}</text>
</block>
</button>
</view>
</template>
2.使用index.wxml代碼
<import src="../../template/nav" />
<view class="flex fix_nav_wp">
<block wx:for="{{navData}}" wx:key="">
<template is="nav" data="{{...item}}"/>
</block>
</view>
<view>首頁</view>
3.index.js邏輯代碼
a.初始化數據
/**
* 頁面的初始數據
*/
data: {
navData: [
{
name: "廣場", //文本
current: 1, //是否是當前頁,0不是 1是
style: 0, //樣式
ico: 'icon-qiugouguanli', //不同圖標
fn: 'gotoIndex' //對應處理函數
}, {
name: "舊物",
current: 0,
style: 0,
ico: 'icon-mingpianjia',
fn: 'gotoOldGoods'
}, {
name: "發布",
current: 0,
style: 1,
ico: '',
fn: 'gotoPublish'
}, {
name: "招領",
current: 0,
style: 0,
ico: 'icon-yikeappshouyetubiao35',
fn: 'gotoRecruit'
}, {
name: "我的",
current: 0,
style: 0,
ico: 'icon-wode',
fn: 'gotoMine'
},
],
},
b.頁面之間的跳轉
gotoOldGoods: function(){
wx.redirectTo({
url: '/pages/oldgoods/oldgoods',
});
},
gotoPublish:function(){
wx.redirectTo({
url: '/pages/publish/publish',
});
},
gotoRecruit:function(){
wx.redirectTo({
url: '/pages/recruit/recruit',
});
},
gotoMine:function(){
wx.redirectTo({
url: '/pages/mine/mine',
});
},
