Let’s focus on the method of jumping and passing values

1. Pass the id to the click event

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

2. Methods Chinese writing method

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))
})
}

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

//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));   
}

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){
