How to store a random value and call it from a click function in selenium webdriver by Jasmine JS?

Question

I want to save a random number between 1 to 31 and use it from a 'click' function in order to click about the saved random number by a 'linkText' locator.

Is it possible?

I need something like:

 var randomDay = Math.floor(31*Math.random() + 1);
 element(by.linkText(randomDay)).click();

The full test is below:

describe('Selenium Test Case', function() {

beforeEach(function(){
    browser.ignoreSynchronization = true;
});

afterEach(function(){
    browser.ignoreSynchronization = false;
});

  it('should execute test case without errors', function() {
    var text, value, bool, source, url, title;
    var TestVars = {};
    var randomDay = Math.floor(31*Math.random() + 1);

browser.get("https://www.mywebsite.com/");
    captureScreen();
browser.driver.sleep(3000);
element(by.xpath("//div[@class='actions-row']//a[.='Schedule Now']")).click();
    captureScreen();
browser.driver.sleep(3000);
element(by.css("div.service-info")).click();
    captureScreen();
browser.driver.sleep(3000);
element(by.css("span.gray-button-style")).click();
browser.driver.sleep(3000);
element(by.linkText("Next")).click();
browser.driver.sleep(3000);
    element(by.linkText(randomDay)).click();
browser.driver.sleep(3000);
element(by.id("class=icon")).click();
browser.driver.sleep(3000);
element(by.linkText("Continue")).click();
element(by.name("email")).sendKeys("idanvcita@gmail.com");
element(by.xpath("(//textarea[@id='agenda'])[2]")).sendKeys("hello again");
element(by.linkText("Submit")).click();
element(by.linkText("Done")).click();
    captureScreen();
browser.driver.sleep(3000);
  });
});

The error is below:

Answer 1

It seems you have a casting error. Try to pass the number as string.

Answer 2

It should be like this:

var randomDay = Math.floor(31*Math.random() + 1);
var randomDayLink = randomDay.toString(); 
element(by.linkText(randomDayLink)).click();
