Thank you for clarifying that you are using AppLab. In AppLab, while the event-driven architecture and basic JavaScript syntax apply, the rules for managing UI elements differ slightly based on how AppLab handles user inputs and outputs.
Here’s a refined and simplified version of your code that aligns with AppLab coding practices:
var name = "";
var meal = "";
var age = 0;
var meals = "";
// Updates the input for age
onEvent("upButton", "click", function() {
age = age + 1;
setNumber("ageOutput", age);
updateScreen();
});
onEvent("downButton", "click", function() {
age = age - 1;
setNumber("ageOutput", age);
updateScreen();
});
// Updates name from input
onEvent("nameInput", "change", function() {
name = getText("nameInput");
updateScreen();
});
// Sets meal based on button clicks
onEvent("option1", "click", function() {
meal = "Vegetarian"; // Example option
updateScreen();
});
onEvent("option2", "click", function() {
meal = "Vegan"; // Example option
updateScreen();
});
onEvent("option3", "click", function() {
meal = "Gluten-Free"; // Example option
updateScreen();
});
// Updates results text based on age and meal type
function updateScreen() {
if (meal === "Vegetarian") {
if (age > 30) {
meals = "Vegetable Omelet with Chicken Sausage";
} else {
meals = "Breakfast Burrito with Scrambled Eggs, Black Beans, and Chicken";
}
} else if (meal === "Vegan") {
if (age > 30) {
meals = "Quinoa Salad with Grilled Chicken";
} else {
meals = "Chicken Tacos with Black Beans & Avocado";
}
} else if (meal === "Gluten-Free") {
if (age > 30) {
meals = "Quinoa Salad with Grilled Chicken";
} else {
meals = "Chicken Tacos with Black Beans & Avocado";
}
} else {
meals = "Please select a meal option."; // Handle no meal option selected
}
// Construct the output text
var text = "Hey " + name + ", the best meal for you to have is " + meals + " when you are " + age + " years old.";
setText("mealOutput", text); // Assuming you have a text area or label with this ID
}
Changes Made for AppLab:
-
Using onEvent("nameInput", "change", ...): Changed to the "change" event for the name input so it updates when the text input changes.
-
Meals Logic: The logic for selecting meals is more streamlined. We check the meal type first and then assign the correct meal based on the age.
-
Default Meal Handling: Included a message when no meal is selected to guide the user to choose an option.
-
Event Binding: Make sure each meal option corresponds to a button click that sets a specific meal type.
Additional Note:
Make sure that the IDs you’re using in setText and getText correspond to the actual element IDs you have in AppLab. Also, if there are any additional logic branches or meal choices you need, you can easily add them to the updateScreen function following the format already established.
