With my limited knowledge of TypeScript, I am attempting to extract a specific number from an expression.
The goal is to locate and retrieve the digit from the following expression.
ID:jv.link.weight:234231
In the given string, I aim to extract the number 234231 using TypeScript. Any suggestions on how to achieve this task would be greatly appreciated, as I am still learning the ropes in TypeScript.
Here's a suggestion:
extractDigits(str) {
let digits = str.replace(/[^0-9]/g, '');
return digits;
}
Employ a regular expression along with the string.match() method:
const text = "ID:jv.link.weight:234231";
text.match(/(\d+)/g)[0]
This code snippet will retrieve 234231
