In this lab you will build a program that collects information about your family and then displays it on the screen.
2. Create a variable called myFamily that is an array. This is where we will store your family.
Example: var myFamily = ;
3. Create a function called build person. It will not have any input parameters, but it will return an object that represents a person.
Inside this function, use individual prompt statements to ask the user for the family members: full name, age, relationship (to you), favorite color, and favorite food. For example: Joe Smith, 79, grandpa, brown, prunes. Collect these bits of data in local variables inside the function. Example: var fullName = prompt("What is their full name?");
Once you have variables that contain each of these items, create a new object that contains these values and add them to the object. Then, return the object from the function.
4. Now that we have a function that builds a person object, we are going to make a do-while loop that will call this function multiple times to create multiple objects.
Create a Boolean variable, then make a while loop as long as that variable is true. Inside the while loop, set the Boolean to the answer you get from a confirm() dialog box that asks if they want to continue adding family members. Example: confirm("Do you want to continue adding family members?");
Also inside the while loop, call the buildPerson() function. Assign the person object that is returned to a variable, then add that variable to the myFamily array. Example, if the person object is in a variable called person you could do this: myFamily.push(person);
5. After the while loop, we need to create a for loop to loop back over the array and print the family members to the web page.
To loop over the array, use a for loop to increment an index variable from 0 to array.length.
Inside the for loop, you can access each individual family member object by using notation like myFamily[i] (assuming your index variable is i.)
To access an individual property of the person, use dot notation. Example: myFamily[i].fullName
6. Output the contents of the each object in HTML to the web page using document.write(). One suggestion would be to output their full name in an < h1> tag and then each of the other properties in a < p> tag.
