Replace comma or whitespace with hyphen in same string
(3 answers)
Closed 2 years ago.
This regex replaces empty spaces with a dash replace(/\s+/g, "-").
If I also want to remove any semicolons, how do I go about adding that to the above regex?
Basically, I want this string hello; how are you to be hello-how-are-you
You could add ; in [] - which means groups and ranges
/[\s;]+/g
const str = "hello; how are you"
const res = str.replace(/[\s;]+/g, "-")
console.log(res)

How to split by commas that are not within parentheses?

How to split string while ignoring portion in parentheses?

Here is the my string
var string = 'Title:(India OR America) OR Keyword:(Education)';
After splitting with "OR" it is showing
["Title:(India", "America)", "Keyword:(Education)"]
But what I need is the below one.
["Title:(India OR America)", "Keyword:(Education)"]
Could anyone please help on how to split the string to get the required result.
To achieve this you'll need to use a negative lookahead to only find the OR string where it's not contained in parentheses. Try this:
var input = 'Title:(India OR America) OR Keyword:(Education)';
var output = input.split(/(?!\(.*)\s?OR\s?(?![^(]*?\))/g);
console.log(output);

How to replace both colon and space with dash in regex?
Here's what I've managed to do:
to replace space: replace(/\s+/g, '-'),
to replace colon: replace(/:\s+/g, '-').
How do I merge these expressions?
You could do something like this:
var text = "hello: hey"
console.log(text.replace(/(:|\s+)/g, "-"))
Returns "hello--hey"
Use an alternation [ :]
var input = "Hello World:Goodbye";
console.log(input);
input = input.replace(/[ :]+/g, '-');
console.log(input);
Note that this replaces actual spaces, not all whitespace characters, which your original version using \s does.

How do I split a string with multiple separators in JavaScript?
(25 answers)
Closed 7 years ago.
My input String is like
abc,def,wer,str
Currently its splitting only on comma but in future it will contain both comma and newline.
Current code as below:
$scope.memArray = $scope.memberList.split(",");
In future I need to split on both comma and newline what should be the regex to split both on comma and newline.
I tried - /,\n\ but its not working.
You can use a regex:
var splitted = "a\nb,c,d,e\nf".split(/[\n,]/);
document.write(JSON.stringify(splitted));
Explanation: [...] defines a "character class", which means any character from those in the brackets.
p.s. splitted is grammatically incorrect. Who cares if it's descriptive though?
You could replace all the newlines with a comma before splitting.
$scope.memberList.replace(/\n/g, ",").split(",")
Try
.split(/[\n,]+/)
this regex should work.

After conversion:

Trim string in JavaScript

Here is a test:
console.log(" Golden Katana of the Unflinching Dawn ".replace(/\s+/g,""))
I want to remove the extra spaces at the end of the string but it removes every space in the string, so how could I remove just the extra spaces at the end and just keep Golden Katana of the Unflinching Dawn?
You can use str.trim() for this case. It removes the leading and trailing whitespace from a string. The regular expression str.replace(/^\s+|\s+$/g,'') will alternatively do the same thing.
try doing
trimmedstr = str.replace(/\s+$/, '');
or maybe
.replace(/ +$/, "");
