2,848 PointsI am not understanding this question. Am I suppose to multiply?
After changing the 5, to the vehicles. I still dont get changing 4 over to 5.
function random_number(4) { // New function called random_choice that takes one parameter, num (or a number)
// Get a random number between 0 and a passed-in number
var num = num || 5 // If no number passed in, default to 4
return Math.floor(Math.random() * num); // Round the answer down (floor) of a random number between 0 and 1 and multiply it by a number. Then return a value and exit the function.
}
function mash_choice() { // New function called mash_choice that doesn't take any parameters
// Since MASH is a special case, give it its own list
var mash = ['boat', 'plane', 'RV', 'motocycle', 'bicycle']; // The array of choices to pick from
var random_number(4); // Use the above function to get a number between 0 and 4
return mash[randomNum]; // Return the list item the random number function just picked and exit the function
}
function get_answer(category) {
// Get a random answer from the available answers in a given category
var choices = []; // A blank array to hold the user provided answer
var selector = 'input[name="' + category + '[]"]'; // Build a CSS selector for the blanks in our passed in category
var inputs = document.querySelectorAll(selector); // Get all of the inputs that match our selector
var answer;
for (var i = 0; i < inputs.length; i++) { // Begin a for loop that will run through the code. i++ = add one to the counter which is "i"
answer = inputs[i].value; // Get the input with the index value of the counter and get the value ie. if they typed in dog, you get back "dog"
if (answer !== '') { // If answer doesn't equal a blank... !== means doesn't equal
choices.push(answer); //...add it to the end of the list
}
}
return choices[random_number(choices.length)]; // Pick and return a random choice choice.length = number of answers the user provided in that category
}
function fill_in_answers(answers) {
// Find the spans that need filled
var home = document.querySelector('#home'); // This says make a new variable and find the HTML tag that has the ID of "home"
var profession = document.querySelector('#profession');
var pet = document.querySelector('#pet');
var location = document.querySelector('#location');
// Fill them with the provided answers
home.innerText = answers['mash'];
profession.innerText = answers['profession'];
pet.innerText = answers['pet'];
location.innerText = answers['location'];
home.innerHTML = answers.mash; // Change the content of the element in the HTML doc with the id "home" to the "mash" value in answers
profession.innerHTML = answers.profession; // Change the content of the element in the HTML doc with the id "career" to the "career" value in answers
pet.innerHTML = answers.pet;
location.innerHTML = answers.location;
}
function handle_submission(evt) {
evt.preventDefault(); // Stop the form from reloading the page
evt.stopPropagation(); // Stop the form from reloading the page
// Build up our answers object
var answers = {
'mash': mash_choice(),
'profession': get_answer('profession'),
'pet': get_answer('pet'),
'location': get_answer('location')
}
// Fill in the answers
fill_in_answers(answers);
var answer_div = document.querySelector('#answers');
answer_div.classList.add('show');
}
// Find the form on the page and attach a handler for when it's submitted
var form = document.querySelector('#mash');
form.addEventListener('submit', handle_submission); // Anytime the form is submitted, we want to call the function handle_submission

Treehouse Moderator 27,696 PointsTry starting the challenge over and doing exactly as the instructions in task 2 ask; no less, no more.
Now change the parameter in the call to random_number directly below your array to say 5 instead of 4.

230,688 PointsThe instructions say to "change the parameter in the call...", which is on line 10.
You won't need to change anything about the function definition.

2,848 PointsIts sad to say I still dont understand the question. I changed the parameter call on line 10 to say
var random_number(random_number);
and its still not working. Ive gone this far and find JS the most difficult.

230,688 PointsBut the instructions don't ask you to change the parameter to say "random_number".
What they do ask is to "change the parameter ... to say 5 instead of 4"
