How to get a URL QueryString Parameter in TMS Web Core?

Question

How can I get a QueryString Parameter Variable from the URL using Delphi code?

Let's assume I have a URL as follows: https://www.example.com/index.html?first_name=shaun&last_name=roselt

How do I get first_name and last_name from the URL?

I want to do this via Delphi only code and not JavaScript.

There's a function called GetQueryParam within the WebLib.WebTools unit that comes with TMS Web Core.

You can use it as follows to get the first_name and last_name parameters:

uses WebLib.WebTools;

...

var
  FirstName, LastName: String;
begin
  FirstName := GetQueryParam('first_name');
  LastName := GetQueryParam('last_name');

  if (FirstName = '') then
    console.log('First Name Not Found!')
  else
    console.log('First Name is ' + FirstName);

  if (LastName = '') then
    console.log('Last Name Not Found!')
  else
    console.log('Last Name is ' + LastName);
end;
