parse:function(str){
			try{
				str=str.substr(0,300);
				var m;	 
				var reg=/<row expect="(\d+?)" opencode="([\d\,]+?)" opentime="([\d\:\- ]+?)"/;
				//<row expect="20160312035" opencode="1,1,7,6,7" opentime="2016-03-12 15:50:00"/> 20160312-36
				if(m=str.match(reg)){
					return {
						type:12,
						time:m[3],
						number:m[1].replace(/^(\d{8})(\d{2})$/, '$1-0$2'),
						data:m[2]
					};
				}

<row expect="20160312035" opencode="1,1,7,6,7" opentime="2016-03-12 15:50:00"/> 现在是返回20160312036
想匹配成20160312-36,请问number:m[1].replace(/^(\d{8})(\d{2})$/, '$1-0$2'), 要怎么改
