微信小程序页面间传参：对象与ID传递详解

gotoDetail(e){
    const music = e.currentTarget.dataset.music;
    // 在小程序中，不同页面之间如何进行参数传递?
    // 既然不能传递对象，所以需要将对象进行类型转换
    // encodeURIComponent : 将内容转换为编码
    wx.navigateTo({
        url:
            "/pages/songDetail/songDetail?music=" + 
            encodeURIComponent(JSON.stringify(music)),
    });
},

Page({
    data:{},
    onLoad(options) {
        console.log( JSON.parse( decodeURIComponent( options.music ) ) );
    },
});

<text
    wx:for={{recommendList}}
    wx:key="id"
    class="iconfont icon-gengduo"
    data-music="{{item}}"
    data-musicId="{{item.id}}"
    bindtap="gotoDetail"
></text>

gotoDetail(e){
    const musicId = e.currentTarget.dataset.musicid;
    wx.navigateTo({
        url:"/pages/songDetail/songDetail?musicId='' + musicId,
    });
},

Page({
    data: {},
    onLoad(options){
        console.log(options.musicId);
    },
});
