WeChat applet's jump to pass parameters and objects

WeChat Mini Program Jump Parameters

Generally, strings are passed to the next page. What if you want to pass objects?

My solution is to first convert the object into a json string and then go to the next page to convert the json string into an object. As follows:

let str=JSON.stringify(e.currentTarget.dataset.item);
wx.navigateTo({
url: '../toMybaby/babyDetail/babyDetail?jsonStr='+str,
success: function (res) {
// success
},
fail: function () {
// fail
},
complete: function () {
// complete
}
})

 onLoad:function(options){
  // 生命周期函数--监听页面加载
  let item=JSON.parse(options.jsonStr);
  this.setData({ward:item});
 },
