微信小程式——傳回上個頁面帶參數

var pages = getCurrentPages();   //目前頁面

var prevPage = pages[pages.length - 2];   //上一頁面

prevPage.setData({

       //直接給上一個頁面指派

      addresschose: that.data.address[index],

});

wx.navigateBack({

     //傳回

     delta: 1

})      

onShow: function () {

let that = this;

let pages = getCurrentPages();

let currPage = pages[pages.length - 1];

if (currPage.data.addresschose) {

    that.setData({

        //将攜帶的參數指派

        address: currPage.data.addresschose,

        addressBack: true

  });

console.log(that.data.address, '位址')

}

}
