原理是取中间的毫秒数,再转换成js的Date类型 function ChangeDateFormat(val) { if (val != null) { var date = new Date(parseInt(val.replace("/Date(", "").replace(")/", ""), 10)); //月份为0-11,所以+1,月份小于10时补个0 var month = date.getMonth() + 1 < 10 ? "0" + (date.getMonth() + 1) : date.getMonth() + 1; var currentDate = date.getDate() < 10 ? "0" + date.getDate() : date.getDate(); return date.getFullYear() + "-" + month + "-" + currentDate; } return ""; }
