uniapp子组件通过uni.navigateBack向父组件传值

//父组件
<Table v-if=land></Table>
//获取子组件信息
onShow() {
	// 移除全局自定义事件监听器
	uni.$off('Data');
	// 监听全局的自定义事件
	uni.$once('Data', data => {
	    this.$set(this.form, "Number", data.Number);
		this.$set(this.form, "Address", data.Address);
		this.$set(this.form, "Area", data.Area);
		this.current = 1
   })
},

//子组件---不能用uni.navigateBack跳转路由，因为父组件已填数据会丢失
	handleTable() {
	uni.$emit('Data', {
		Number: this.inforObj.Number,
		Address: this.inforObj.Address,
		Area: this.inforObj.Area,
	});//判断是否刷新
	let canNavBack = getCurrentPages()
		if( canNavBack && canNavBack.length>1) {  
			 uni.navigateBack() 
		} else {  
		 history.back();  
	   } 
}
