用js将从后台得到的时间戳（毫秒数）转换为想要的日期格式

先重写Dated的toLocaleString方法：

Date.prototype.toLocaleString = function() {
          return this.getFullYear() + "/" + (this.getMonth() + 1) + "/" + this.getDate() + "/ " + this.getHours() + ":" + this.getMinutes() + ":" + this.getSeconds();
    };

假设时间毫米数是10000,

var time = new Date(10000);

timeStr = time.toLocaleString();
