在asp.net mvc后台返回到视图中的json数据中想对数据进行操作,发现日期类型无法直接进行操作,需要转换为指定格式才行.在网上也搜了下方法也很多,觉得有点麻烦,最终使用正则搞定了,分享下:

var jsondate="/Date(1415169703000)/";

var formatdate=eval(jsondate.replace(/\/Date\((\d+)\)\//gi, "new Date($1)"));

alert(formatdate.toLocaleDateString());

有时取得的日期可能为这种类型"/Date(1415169703000+0800)/",这时代码就需要调整下了:

 var jsondate="/Date(1415169703000+8000)/";

 var formatdate=eval(jsondate.replace(/\/Date\((\d+)([\+\-](\d\d)(\d\d))?\)\//gi, "new Date($1)"));

 alert(formatdate.toLocaleDateString());

运行结果如下:
