Error Retrieving substring from larger text source in Protractor

Question

I am trying to extract a URL from a registration email in my end-to-end test for Protractor, but I am getting errors trying to parse the larger string.

The error I am getting is:

Here is the code:

// spec.js
describe('MockMock', function() {

  var tRegMessage = element(by.className('well'));
  var tabledata = $$('./table');
  // get rows 
  var rows = tabledata.all(by.tagName("tr"));
  // get cell values
  var cells = rows.all(by.tagName("td"));


  var commonfunctions = require('./CCCommonFunctions.js');

  function clickRegistration(email) {
    element(by.xpath("//td[. = '" + email + "']/following-sibling::td/a")).click();
}

  function getRegLink(regText) {
      var startUrl = regText.indexOf("http://");
      var endUrl = regText.indexOf("Thank you",startUrl);
      getRegLink = regText.substring(startUrl,endUrl);
  }

  function Login(username, password) {
    fUserName.sendKeys(username);
    fPassword.sendKeys(password);
    commonfunctions.ccClick(bLoginButton);
  }

  beforeEach(function() {
    browser.waitForAngularEnabled(false);
    browser.get('http://ns-rd-app-wi:2525/');
  });

it('Get verification link', function() {
    clickRegistration('[email protected]');
    browser.get(getRegLink(tRegMessage));
    browser.pause();
  });

  });

How should I be parsing strings in protractor? I'm too used to vbscript, it seems.

==================================================================

I've made changes based on the comments below, but I am still stuck:

describe('MockMock', function() {

  var tRegMessage = element(by.className('well'));
  var tabledata = $$('./table');
  // get rows 
  var rows = tabledata.all(by.tagName("tr"));
  // get cell values
  var cells = rows.all(by.tagName("td"));


  var commonfunctions = require('./CCCommonFunctions.js');

  function clickRegistration(email) {
    element(by.xpath("//td[. = '" + email + "']/following-sibling::td/a")).click();
}

  function getRegLink(regMessage) {
  return new Promise(resolve => {
    regMessage.getText().then(text => {
      var startUrl = text.indexOf("http://");
      var endUrl = text.indexOf("Thank you",startUrl);
      resolve(text.substring(startUrl,endUrl-2))
    }  ) 
  })         
}

  beforeEach(function() {
    browser.waitForAngularEnabled(false);
    browser.get('http://ns-rd-app-wi:2525/');
  });


it('Get verification link', function() {
    clickRegistration('[email protected]');
    var regURL=getRegLink(tRegMessage.getText());
    browser.get(regURL.toString());
    browser.pause();
  });

});

This gives a new error now: Failed: unknown error: unhandled inspector error: {"code":-32000,"message":"Cannot navigate to invalid URL"} (Session info: chrome=71.0.3578.98) (Driver info: chromedriver=2.46.628402 (536cd7adbad73a3783fdc2cab92ab2ba7ec361e1),platform=Windows NT 10.0.16299 x86_64)

You got error on line:

browser.get(getRegLink(tRegMessage));

Because tRegMessage is not string. It is ElementFinder (you got it from this line element(by.className('well'));) So, you need take a text from this element. For example:

it('Get verification link', function() {
    const url = tRegMessage.getText();
    clickRegistration('[email protected]');
    browser.get(getRegLink(url));
    browser.pause();
  });

Also, your method getRegLink() does not return string. So, after first fix you will get an error that browser.get() should have argument string
