Ouput:- Date: 2021-11-08 16:56:42 LoginID: pvgA1245 Password: Root@123 it's one of the example which is in file i want LoginID value i.e "pvgA1245 and password value i.e Root@123
Please , help me how can i make it!!!
there are hundreds of solutions to this problem, some having advantages in different scenarios then others.
Here are some for using split() or using a regex match. Each either using destructuring or just "normally assign" the variables. Regex has the advantage, that it can be used more flexible for example if sometimes the line schema is different and Password is missing. But if you can be sure that the schema is always the same or just wanna skip lines that don't have all values, split() is totally fine.
You would just add the relevant code snippet inside your for loop
let i = "Date: 2021-11-08 16:56:42 LoginID: pvgA1245 Password: Root@123";
// split and destructure
const [ , , , , id, ,pw,] = i.split(" ");
console.log(id, pw);
// split and normally assign
const a = i.split(" ");
const id2 = a[4];
const pw2 = a[6];
console.log(id2, pw2);
// regex and destructure
const [, id3, pw3] = i.match(/(?:LoginID: ([^\s]*)) ?(?:Password: ([^\s]*))/);
console.log(id3, pw3);
// regex and normally assign
const m = i.match(/(?:LoginID: ([^\s]*)) ?(?:Password: ([^\s]*))/);
const id4 = m[1];
const pw4 = m[2];
console.log(id4, pw4);
