var date = “02-25-2010”;
var myregexp2 = new RegExp(“-.”);
dateArray = date.split(myregexp2);
What is the correct regex for this any and all help would be great.
You need the put the characters you wish to split on in a character class, which tells the regular expression engine “any of these characters is a match”. For your purposes, this would look like:
Although dashes have special meaning in character classes as a range specifier (ie
[a-z] means the same as
[abcdefghijklmnopqrstuvwxyz]), if you put it as the last thing in the class it is taken to mean a literal dash and does not need to be escaped.
To explain why your pattern didn’t work,
/-./ tells the regular expression engine to match a literal dash character followed by any character (dots are wildcard characters in regular expressions). With “02-25-2010”, it would split each time “-2” is encountered, because the dash matches and the dot matches “2”.
or just (anything but numbers):
you could just use
Then split it on anything but numbers:
Say your string is:
let str = `word1 word2;word3,word4,word5;word7 word8,word9;word10`;
You want to split the string by the following delimiters:
- New line
You could split the string like this:
let rawElements = str.split(new RegExp('[,;\n]', 'g'));
Finally, you may need to trim the elements in the array:
let elements = rawElements.map(element => element.trim());
or just use for date strings 2015-05-20 or 2015.05.20
