Slice a string in javascript and manipulate it

Question

My variable is:

var filePath = "C:\\Libraries\\Documents\\123_test\\Report_11071991";

I have a variable as above in javascript

Can I have some code to get only the numeric part(11071991) from the last folder(Report_11071991)?

Did you mean javascript? `var filePath...` is not a valid variable declaration in Java (yet). — assylias, Jul 13 '17 at 09:01
how about a regex like `parseInt(/Report_(.*)$/.exec(filePath)[1], 10)` — Sid Vishnoi, Jul 13 '17 at 09:38

This is bad example, because no proffessional code. Please read articles for regular expression Pattern, Matcher.

public class Test {
  public static void main(String[] args) {
    String filePath="C:\\Libraries\\Documents\\123_test\\Report_11071991";

    String[] lines = filePath.split("_");
    filePath=lines[lines.length-1];

    System.out.println(filePath);

 }

}

OP change to javascript. Your java code won't help him – Ori Marko Jul 13 '17 at 16:32

var filePath = "C:\\Libraries\\Documents\\123_test\\Report_11071999";

var lastFolderName = filePath.substring(filePath.lastIndexOf("\")); //Report_11071999

if (lastFolderName.indexOf("Report_") >= 0) {

var out = lastFolderName.substring(7);

}

else {

out = lastFolderName;

}
