Carte coupée dans la barre de tabulation du mini programme WeChat-Développement de mini-programmes-php.cn

Récemment, alors que je recherchais des mini-programmes, j'ai rencontré un problème, qui est la coupe de la barre de tabulation. Il y a un fragment sur Android, et un composant tiers est également fourni sur RN. Le mini-programme WeChat ne semble pas en avoir. un composant dédié. Il m'a fallu beaucoup de temps pour implémenter cette fonction, même si de nombreuses personnes ont implémenté cette fonction, j'ai trouvé que soit elle ne répondait pas à mes besoins, soit elle était trop lourde à mettre en œuvre. Je me suis donc référé à des blogs rédigés par de nombreux experts et j'en ai mis en place un qui répondait à mes besoins. Codez d’abord.

Regardez d'abord le fichier js :

const util = require(&#39;../../utils/util.js&#39;);
Page({
    data: {
        navTab:["投资","理财"],
        /**
         * 页面配置
         */
        winWidth: 0,
        winHeight: 0,
        // tab切换
        currentTab: 0,
        arrayList:[1,2,3,4,5,6,6,7,6,3,2,1,8,9,6,0,4],
        modalHidden:true,
        content:"这是一个表情",
        imagesHeightList:[],
        imageList:[
            "../../images/image1.jpg",
            "../../images/image2.jpg",
            "../../images/image3.jpg",
        ],
        datalist:[
            "../../images/image1.jpg",
            "../../images/image2.jpg",
            "../../images/image3.jpg",
        ],
    },
    /** 
     * 页面初始化
     * options 为页面跳转所带来的参数
     */
    onLoad: function (options) {
        var that = this;
        /**
         * 获取系统信息
         */
        wx.getSystemInfo({
            success: function (res) {
                that.setData({
                    winWidth: res.windowWidth,
                    winHeight: res.windowHeight
                });
            }
        });
        
        
    },
    onReady: function () {
       
       
    },
/**
 * 显示弹窗
 */
    modalShow:function(){
        var that = this;
        that.setData({
            modalHidden:false,
        });
    },
/**
 * 点击取消，确认按钮
 */
modalChange:function(){
    var that = this;
        that.setData({
            modalHidden:true,
        });
},
    /**
     * 滑动切换tab
     */
    bindChange: function (e) {
        var that = this;
        that.setData({
             currentTab: e.detail.current 
             });
    },
    /**
     * 点击tab切换
     */
    swichNav: function (e) {
console.log("--------");
        var that = this;
        if (that.data.currentTab === e.target.dataset.idx) {
            return false;
        } else {
            that.setData({
                currentTab: e.target.dataset.idx
            })
        }
