uniapp implements jump page postback Data method:

First introduce the most original jump method, which is similar to the a tag in html, but in uniapp you need to replace the a tag with a5326a12123338c823426d0a96a021e0...9a67f2adf02d82de7f8f0475590779aa

Let’s focus on the method of jumping to pass value

1. Pass in the id to the click event

<view @tap="toOpportnity(item.id)">转商机</view>；

2. Write methods in Methods

toOpportnity(id){
uni.navigateTo({        //点击跳转的方法
url:'opportunity-form?id='+id     //需要跳转的页面路径，使用问号进行id的传值，然后再拼接一个要传入的id//对象传参方式 url:'../../pages/disabled/subsidie?listObj=' + encodeURIComponent(JSON.stringify(obj))
})
}

3. Receive parameters on the details page

Write an onLoad function

onLoad(options){    //传入的参数名称，可自行修改
// console.log(options);    查看传入的id值

Receive method for object parameters

//this.leadobj(上个页面传过来的对象名称，即？后面的那个名称) = JSON.parse(decodeURIComponent(options.leadobj));   
}

The reception of a single parameter is introduced here using id

First of all, the passed id must be assigned a value

Request interface, the url address of the interface must be followed by the passed id id【/${this.id}/】

The complete steps are as follows:

onLoad(options){
this.id = options.id;
console.log('传过来的id值为：' + options.id);
let that = this
uni.request({
url:`${this.$serverUrl}/opportunity/${this.id}/`,
header:{
'Authorization': this.uerInfo.token
},
success(res){
console.log(res)
that.opportunity = res.data;
}
})
}对象传参报错解决方案
