I have to verify if my string contains a substring followed by a regex.

Lets say the string looks like: "Abcd 03:02:01"

How can i verify that the string contains the substring "Abcd" and the regex for "03:02:01". I am using jscript in TC9.

I tried using find for the Substring and checked regex using Test.This involves checking the input string twice in If loops. But is there any other way to do this?

Thanks

  • `/Abcd \d\d:\d\d:\d\d/` (this requires it to be `Abcd DIGITDIGIT:DIGITDIGIT:DIGITDIGIT`). – h2ooooooo Apr 25 '14 at 16:06
  • Yes, why don't just include Abcd in the regex? – PeterWong Apr 25 '14 at 16:08
  • Thanks for you response. But how can i use it to search in the input string.The string Abcd keeps changing ,hence cannot really add it in regex – user2993178 Apr 25 '14 at 16:09
  • Currently i am checking the input string in two parts. var check=aqString.Find(Inputstring,"Abcd",0) var matches=regex.test(Inputstring) if(check !=1){ if(matches) //do something } – user2993178 Apr 25 '14 at 16:15

If I understood well your question, you want to match the existence of Abcd 03:02:01in a string, based on that, you can use:

var s = "Abcd 03:02:01";
if (/^Abcd \d{2}:\d{2}:\d{2}$/.test(s)) {
    // Successful match
} else {
    // Match attempt failed
}

You can use variables in a regex expression.

var str = "Abcd 03:02:01";
var beginning = "Abcd"; 
var pattern= RegExp(beginning + " \\d\\d:\\d\\d\\:\\d\\d"); 
var result = pattern .test(str); //bool return
