1. index.js

Page({

    /**
     * 页面的初始数据
     */
    data: {
        currentData: 0,
    },
    /**
     * 生命周期函数--监听页面加载
     */
    onLoad: function (options) {
    },
    //获取当前滑块的index
    bindchange: function (e) {
        const that = this;
        that.setData({
            currentData: e.detail.current
        })
    },
    //点击切换，滑块index赋值
    checkCurrent: function (e) {
        const that = this;

        if (that.data.currentData === e.target.dataset.current) {
            return false;
        } else {

            that.setData({
                currentData: e.target.dataset.current
            })
        }
    }
})
