Conversion between a Date object and a string in JavaScript

Using the data object from the new date () in JS to convert to a string often fails to meet the expectations we want, and today I'm going to make a simple analysis of the topic "Conversion between Date objects and strings":

Common ways to convert are:

One, toString ()--Converts the Date object to a string

1 var New Date (). toString (); 2     Console.log (str); 3 4 // Output: 5 // Mon Oct 11:13:22 gmt+0800

Second, totimestring ()--Converts the time portion of a Date object to a string

1 var New Date (). totimestring (); 2     Console.log (str); 3 // Output: 4 // 11:16:31 gmt+0800

Three, todatestring ()--Converts the date part of a Date object to a string

1 var New Date (). todatestring (); 2     Console.log (str); 3 // Output: 4 // Mon Oct

It is obvious that the conversion results from the above three methods do not meet our expectations and require further processing before the Date Object can be converted to a time string that is easy to display or interact with the background , as follows:

To define a function:

1 //To define converting a Date object to a string function2 functiontimetostring (timeobj) {3     varstr = "";4     varYear =timeobj.getfullyear ();5     varmonth =timeobj.getmonth ();6     varDate =timeobj.getdate ();7     varTime = Timeobj.totimestring (). Split ("") [0];8     varRex =NewREGEXP (/:/g);9str = year+ "-" +month+ "-" +date+ "" +time.replace (Rex, "-");TenConsole.log ("------Current date:" +str); One     returnstr; A } -  - //to define a conversion to a string function by timestamp the functionTimetoobj (mstime) { -     varD =NewDate (); - D.settime (mstime); - timetostring (d); +}

Execute function:

1 //To define converting a Date object to a string function2 varD =NewDate ();3 timetostring (d);4 //Output:5 //------Current Date: 2015-9-12 11-43-286 7 //to define a conversion to a string function by timestamp8Timetoobj (1444617383284);9 //Output:Ten //------Current Date: 2015-9-12 10-36-23

You can refer to the Date object API:

Summarize:

This analysis process is not only a practical application of my summary, but also for the browser to provide a solution to this kind of related problems, is purely a point of view, I hope that the browser can be more in-depth analysis, and write a more complete system of conversion rules.
