如何在JavaScript中修剪日期+时间字符串的时间部分

Question

I am receiving json data in my javascript as a list of strings that contain date and time of certain events.

I construct an array and store these in the array.

However the storage is in the format of dd/mm/yyyy hh:mm:ss. I was wondering if there is a way to just extract the date part of this string from the array.

// run a loop to parse thru all elements in the array. //
t = (Service_date_from[count]); // 't' is what contains the date time once extracted from the array with a counter variable called `count`

Is there any kind of date formating functionality in javascript?

Answer 1

If it's always formatted that way, you can simply use substr

var idx = t.indexOf(" ");
var timeStr = t.substr(idx + 1);
