函数封装：

/** * 获取当前时间 * 格式YYYY-MM-DD */Vue.prototype.getNowFormatDate = function() {  var date = new Date();  var seperator1 = "-";  var year = date.getFullYear();  var month = date.getMonth() + 1;  var strDate = date.getDate();  if (month >= 1 && month <= 9) {    month = "0" + month;  }  if (strDate >= 0 && strDate <= 9) {    strDate = "0" + strDate;  }  var currentdate = year + seperator1 + month + seperator1 + strDate;  return currentdate;};
