vue/java 感觉身份证号获取年龄

Vue代码如下 

 getAge(){//根据身份证号获取年龄
			    	var birthday = this.insuredIdNo.substring(6,10)+"-"+this.insuredIdNo.substring(10,12)+"-"+this.insuredIdNo.substring(12,14);
			    	let birthdays = new Date(birthday.replace(/-/g, "/"));//被保险人生日
			    	let d = new Date(this.T_EFFECTIVETIME.replace(/-/g, "/"));//保单起期
			    	let age =
			    	d.getFullYear() -
			    	birthdays.getFullYear() -
			    	(d.getMonth() < birthdays.getMonth() ||
			    	(d.getMonth() == birthdays.getMonth() &&
			    	d.getDate() < birthdays.getDate())? 1: 0);
			    	console.log("年龄为"+age);
			    	return age;
			    },
