The method of realizing the date format of the string conversion by JS _javascript tips

This article illustrates the method of JS to implement the date format of string conversion. Share to everyone for your reference. The specific analysis is as follows:

We all know that JS is based on the results to determine the data type.
Of course, we can also transform, the following I will introduce two types of JS string type conversion to date types of methods,
My personal favorite is the first method.
Do you have any other good way to share it.

1.eval method Conversion method,---Recommended to use this method

I've written a way, everybody. Call directly

<script type= "Text/javascript" >
//String date format, strdate string function to be converted to date format
getDate (strdate) {
  var Date = eval (' new Date ' + Strdate.replace (/\d+ (? =-[^-]+$)/, 
   function (a) {return parseint (A, 10)-1;}). Match (/\d+/g) + ') ');
  return date;
}
Test
alert (getDate ("2012-05-09"));
</script>

2. The second approach is to use split-fraction groups. This is not recommended because the date format is not flexible
Methods are as follows

<script type= "Text/javascript" > 
//String date format, strdate string function to convert to date format 
getDate (strdate) { 
  var st = Strdate; 
  var a = St.split (""); 
  var B = a[0].split ("-"); 
  var c = a[1].split (":"); 
  var date = new Date (b[0], b[1], b[2], c[0], c[1], c[2]);
  return date; 
} 
Test 
alert (getDate ("2012-9-20 19:46:18")); 
</script> 

The effect is as follows

I hope this article will help you with your JavaScript programming.
