uniapp中的跳转传参和接收参数

//A页面传递多个参数 
uni.navigateTo({
            url: `/pagesA/pages/addPosts/addPosts?potos=${type}&topicId=${vm.topicId}&tName=${vm.topicInfo.name}&tId=${vm.topicInfo.id}`
          })

// B页面接收参数

onLoad(options) {
            console.log(options, '999999999')
            this.addName=options.tName
            this.topId = options.tId
        },

// A2页面编辑的时候传参一个对象
    editFp(item,index){
                console.log(item, '发票信息')
                const params = {}
                params.id = item.id
                params.invoiceType = item.invoiceType
                params.companyName = item.companyName
                params.titleName = '编辑发票'
                
                // uni.setStorageSync('invoiceObj',JSON.stringify(item))
                uni.navigateTo({
                    url:'./addNewInvoiceIn?items='+encodeURIComponent(JSON.stringify(item))
                })
            },

// B2页面onload里面接收参数
    onLoad(option) {
                const invoiceObj = JSON.parse(decodeURIComponent(option.items))
   }
