js部分

redio_cli(e,ind){
	this.xuanx.push(e)
	console.log(this.xuanx)
	let list = []
	for (var i = 0; i < this.xuanx.length; i++) {

				list.push(this.xuanx[i])
				// console.log(list)
			}
		}
	}
	// console.log(list)
	// 判斷重複刪除
	for (var i = 0; i < this.xuanx.length; i++) {

			}
		}
	}
	//按鈕變色
	if (this.xuanxind.indexOf(ind) == -1) {
		this.xuanxind.push(ind);//選中新增到數組裡
		console.log(this.xuanxind)
	} else {
		this.xuanxind.splice(this.xuanxind.indexOf(ind), 1); //取消
	}
