I have a textNode in which i have the data coming like this data=$(2000)%,so i want to separate out the symbols and number.
let preText = ''
let number = ''
let postText = ''
let data = '$(2000)%'
const regex = new RegExp(`(\(\[)?[0-9]{1,3}(?:,[0-9]{1,3})*(\.[0-9]{1,5})?(\)\])?`);
data.match(regex)
Output expected:
preText = '$('
number = '2000'
postText = ')%'
Another example: if data=$2,23,603, the output should be preText=$, number=2,23,603 and postText=.
I'm not able to achieve this with different variables,how can i get the desired output?
You can use
const data = '$(2000)%';
const regex = /^(.*?)((?:\d{1,3}(?:,\d{1,3})*|\d+)(?:\.\d{1,5})?)(\D.*)?$/;
const [_, preText, number, postTex] = data.match(regex);
console.log([preText, number, postTex]);Details:
^ - start of string(.*?) - Group 1 (preText): any zero or more chars other than line break chars, as few as possible((?:\d{1,3}(?:,\d{1,3})*|\d+)(?:\.\d{1,5})?) - Group 2 (number): one to three digits followed with zero or more occurrences of a comma and one to three digits, or just one or more digits, and then an optional sequence of a . and one to five digits(\D.*)? - Group 3 (postTex), optional: a non-digit char and then any zero or more chars other than line break chars, as many as possible$ - end of string.Some notes about the pattern:
Uncaught SyntaxError: Invalid regular expression: /(([)?[0-9]{1,3}(?:,[0-9]{1,3})*(.[0-9]{1,5})?()])?/: Unterminated group
[0-9]{1,3} can only match 1-3 digits.\(\[ will only match when both ([ are present$ or % so that can not be in the outputWhat you could do it either capture all the possible symbols in groups on the left and the right using a character class like [$\[(]
([$\[(]*)\b((?:[0-9]{1,3}(?:,[0-9]{1,3})*(?:\.[0-9]{1,5})?)|\d+)\b([\])%]*)
Or optionally match all non digits \D* around matching the digits:
(\D*)\b((?:[0-9]{1,3}(?:,[0-9]{1,3})*(?:\.[0-9]{1,5})?)|\d+)\b(\D*)
If there is a match, the capture group numbers are 1, 2 and 3:
let data = '$(2000)%'
const regex = /([$\[(]*)\b((?:[0-9]{1,3}(?:,[0-9]{1,3})*(?:\.[0-9]{1,5})?)|\d+)\b([\])%]*)/;
const m = data.match(regex);
console.log(m);
if (m) {
preText = m[1];
// etc..
}
