js获取当前时间：yyyy-MM-dd HH:MM:SS

var nowDate = new Date();var year = nowDate.getFullYear();
 
 var month = nowDate.getMonth() +  <  ? "" + (nowDate.getMonth() + ): nowDate.getMonth() + ;
 
 var day = nowDate.getDate() <  ? "" + nowDate.getDate() : nowDate.getDate();
 
  var hours = nowDate.getHours()<?"" + nowDate.getHours():nowDate.getHours();
var minutes = nowDate.getMinutes()<?"" + nowDate.getMinutes():nowDate.getMinutes();
var seconds = nowDate.getSeconds()<?"" + nowDate.getSeconds():nowDate.getSeconds();
 
 var dateStr = year + "-" + month + "-" + day+ " " + hours+ ":" + minutes+ ":" + seconds;
 console.log(dateStr);

这是结果

我要转html5和js，哎，其实还挺喜欢写后端的，但是希望自己转变一下，加油吧
