				selectId: [],
 
//选择按钮
			choice(index) {
				console.log('index', index)
				//当再次被选中时，取消当前选中项
				if (this.typeList[index].selected == true) {
					this.typeList[index].selected = false;
					//取消选中时删除数组中的值
					for (var i = 0; i < this.selectId.length; i++) {
						if (this.selectId[i] === this.typeList[index].title) {
							this.selectId.splice(i, 1);
 
						}
					}
					this.selectList = this.selectId
					console.log("选中的值", this.selectId)
				} else {
					this.typeList[index].selected = true;
					this.selectId.push(this.typeList[index].title)
					for (var i = 0; i < this.selectId.length; i++) {
						console.log("选中的值", this.selectId[i])
					}
					this.selectList = this.selectId
					console.log("选中的值", this.selectId)
				}
