提问by James
In my javascript i enter date in below format as string
在我的 javascript 中,我以以下格式输入日期作为字符串
12.12.2014
I want to convert to JSON date format like below
我想转换为如下的 JSON 日期格式
/Date(1358866800000)/
How could i achieve this. I tried below code which converts to JSON format but doesnt work.
我怎么能做到这一点。我尝试了下面的代码,它转换为 JSON 格式但不起作用。
function convertToJSONDate(strDate){
var dt = new Date(strDate);
var newDate = new Date(Date.UTC(dt.getFullYear(), dt.getMonth(), dt.getDate(), dt.getHours(), dt.getMinutes(), dt.getSeconds(), dt.getMilliseconds()));
return '/Date(' + newDate.getTime() + ')/';
}
When i try to use above function like convertToJSONDate("12.12.2014")
, i get date like this '/Date(NaN)/
当我尝试使用上述功能时convertToJSONDate("12.12.2014")
,我得到这样的日期'/Date(NaN)/
How could i achieve this?

The string you are passing to Date's constructor is not valid
您传递给 Date 构造函数的字符串无效
function convertToJSONDate(strDate){
var splitted = strDate.split(".");
var dt = new Date(splitted[2],splitted[0],splitted[1]);
var newDate = new Date(Date.UTC(dt.getFullYear(), dt.getMonth(), dt.getDate(), dt.getHours(), dt.getMinutes(), dt.getSeconds(), dt.getMilliseconds()));
return '/Date(' + newDate.getTime() + ')/';
}
convertToJSONDate("12.1.2014");
Another simplified version could be:
另一个简化版本可能是:
function convertToJSONDate(strDate){
var splitted = strDate.split(".");
//var dt = new Date(splitted[2],splitted[0],splitted[1]);
var newDate = new Date(Date.UTC(splitted[2], splitted[0], splitted[1]));
return '/Date(' + newDate.getTime() + ')/';
}
convertToJSONDate("12.1.2014");

@AlexBcn Great answer, but you need to subtract 1 from the month because months are zero-based.
@AlexBcn 很好的答案,但您需要从月份中减去 1,因为月份是从零开始的。
function convertToJSONDate(strDate){
var splitted = strDate.split(".");
var newDate = new Date(Date.UTC(splitted[2], (splitted[1] - 1), splitted[0]));
return '/Date(' + newDate.getTime() + ')/';
}
//console.log(convertToJSONDate("10.01.2018"));
//Output: Wed Jan 10 2018 01:00:00 GMT+0100 (Central European Standard Time)
//Output without subtraction: Sat Feb 10 2018 01:00:00 GMT+0100 (Central European Standard Time)
