Js implements the string to date format method, js Date Format

This document describes how to convert a string to a date format in JavaScript. Share it with you for your reference. The specific analysis is as follows:

As we all know, JS determines the data type based on the results.
Of course, we can also convert it. Next I will introduce two methods for converting the JS string type to the date type,
I personally prefer the first method.
You can share some other good methods.

1. eval method conversion method --- this method is recommended

I wrote a method. You can call it directly.

<Script type = "text/javascript"> // convert string to date format. function getDate (strDate) is a string to be converted to date format) {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 method is to split the array. It is not recommended because the date format is not flexible.
The method is as follows:

<Script type = "text/javascript"> // convert string to date format. function 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 ("19:46:18"); </script>

The effect is as follows:

I hope this article will help you design javascript programs.
