页面1

async getListTransferAndApprova() {
//把mark值拼接到路径的后面，定义一个变量，使得切换穿的mark都不一样
		let mark = '';
		if (this.tabsCurrent === 0) {
		    mark = '2';
		  } else if (this.tabsCurrent === 1) {
		    mark = '3';
		  }else if (this.tabsCurrent === 2) {
		    mark = '4';
		  }else if (this.tabsCurrent ===3) {
		    mark = '5';
		  }
	  const data ={
	        mark:mark,
	        query:this.queryParams
	      }
		const res = await listTransferAndApprova(data)
		uni.hideLoading()
		this.requestList = res.rows
	},
	//点击时跳转把mark也传递过去
	detail(item) {
			let mark = '';
			if (this.tabsCurrent === 0) {
				mark = '2';
			} else if (this.tabsCurrent === 1) {
				mark = '3';
			} else if (this.tabsCurrent === 2) {
				mark = '4';
			} else if (this.tabsCurrent === 3) {
				mark = '5';
			}
	     item.mark = mark;
			uni.navigateTo({
				url: `/subpkg/allot/allotAuditDetail?item=${JSON.stringify(item)}&itemId=${this.tabsCurrent}`
			});
		},

页面2
来接收传递过来的数据

		/**接收传递过来的数据*/
		onLoad(option) {
			this.title = parseInt(JSON.parse(option.itemId))
			if (option.item) {
				const item = JSON.parse(option.item);
				console.log(item);
				this.dataDetail = item
			}
		},

打印出来的，mark已被接收
