我们在程序用往往通过ajax方式返回json数据,json中包含Date对象时,在js中是Object对象。可以方式获取:
1.new Date(yourJsonDate.time); //你用你的返回Date对象的time值 新建一个js的Date对象。
2.对Js 的Date对象进行格式化。参考以下方法:
javascript Date format(js 日期格式化)

// 对Date的扩展,将 Date 转化为指定格式的String // 月(M)、日(d)、小时(h)、分(m)、秒(s)、季度(q) 可以用 1-2 个占位符, // 年(y)可以用 1-4 个占位符,毫秒(S)只能用 1 个占位符(是 1-3 位的数字) // 例子: // (new Date()).Format("yyyy-MM-dd hh:mm:ss.S") ==> 2006-07-02 08:09:04.423 // (new Date()).Format("yyyy-M-d h:m:s.S") ==> 2006-7-2 8:9:4.18 Date.prototype.Format = function
