js根据身份证号取日期和性别

 //card是身份证  sr是生日
        function cardData(){
        	var card = $("#cardNumber").val();//身份证号
        	var sr = $("#birthday").val();
        	var cE = /^\d{6}((?:19|20)(?:(?:\d{2}(?:0[13578]|1[02])(?:0[1-9]|[12]\d|3[01]))|(?:\d{2}(?:0[13456789]|1[012])(?:0[1-9]|[12]\d|30))|(?:\d{2}02(?:0[1-9]|1\d|2[0-8]))|(?:(?:0[48]|[2468][048]|[13579][26])0229)))\d{2}(\d)[xX\d]$/;
	  		if(card.length>0 && cE.test(card)){//身份证
	  			if(sr.length<1){//生日没值
	  				var t = RegExp.$1;
	  				var y=t.substr(0,4);
		 			var m =t.substr(4,2);
		  			var d = t.substr(6,4);
		  			$("#birthday").val(y+"-"+m+"-"+m);
	  			}
	  		}
        }
