LAB 3 Random Story Generator DESCRIPTION Using the HTML, CSS and JavaScript code provided to you, modify the JavaScript so that the page that does the following: 1. Generates a random story in a paragraph when the user pressed the button. 2. Replaces the default name "Bob" in the story with a custom name, but only if a custom name is entered into the "Enter custom name" text field before the generate button is pressed. 3. Converts the default imperial weight (pounds) and temperature (F) values to kilograms (kg) and centigrade (C) if the metric radio button is checked before the generate button is pressed. 4. Will generate another random silly story if you press the button again (and again...). INSTRUCTIONS Follow along with the numbered instructions inside the code comments in the provided JavaScript file. EVALUATION Criteria The above tasks have been completed Mark /4 This lab based on the excellent assessment challenge at https://developer.mozilla.org/en-US/docs/Learn/JavaScript/First_steps/Silly_story_generator Image credit:

// VARIABLE DECLARATIONS

/* STEP 1: Declare and initialize variables - customName for the name field - randomize for the button - story for the paragraph that outputs the final story */

/* STEP 3: Create the variable that contains the story string that will be modified - use var storyText to containt the following: 'It was 94 farenheit outside, so :insertx: went for a walk. When they got to :inserty:, they stared in horror for a few moments, then :insertz:. Bob saw the whole thing, but he was not surprised :insertx: weighs 300 pounds, and it was a hot day.' */

/* STEP 4: Create three arrays, insertX, insertY, and insertZ, assigning them the following array values respectively: Donald Trump, Jackie Chan, Santa Claus Area 51, Death Valley, Aruba spontaneously combusted, rapidly sublimated, evaporated instantly */

// FUNCTIONS

/* STEP 2: have a look at the following function - if you call this function and pass it an array, it will return one of the elements of that array randomly */ function randomValueFromArray(array){ return array[Math.floor(Math.random()*array.length)]; }

/* STEP 6: Review the partially complete result() function below */ function result() { // STEP 7: Create a new variable called newStory and set it to the value of storyText - we don't want to overwrite the original story!

/* STEP 8: Use the randomValueFromArray() function to generate a value for each of three new variables - xItem, yItem, and zItem Call up the function and for each variable, pass it the array from which to grab a random string - for example if insertW was an array of strings, I would type: var wItem = randomValueFromArray(insertW);

/* STEP 9: Replace the three placeholders in the newStory string :insertx:, :inserty:, and :insertz: with the strings stored in xItem, yItem, and zItem. Each time, be sure to update the variable newStory (with +=). You might need to do one of the above replacements twice! */

/* STEP 10: If the user has typed a name in the customName field, replace the name 'Bob' in the story with whatever they typed */ if(customName.value != '') {

} /* STEP 11: If the metric radio button has been checked, we need to convert the temperature and mass numbers in the story */ if(document.getElementById("metric").checked) { // STEP 11a: Create a variable called weight and convert the 300lbs to kgs (1lb = 0.453592kg) // STEP 11b: Replace the string 300 pounds with the updated weight in kg

// STEP 12a: Create a variable called temp and convert F to C ... the formula for conversion is C = (F - 32) x 5/9

// STEP 12b: Replace the string '94 fahrenheit' with the updated temperature in C

} /* STEP 13: Make the textContent property of the story variable (which references the paragraph) equal to newStory */

// The following line makes the paragraph visible story.style.visibility = 'visible'; }

// EVENT LISTENERS /* STEP 5: Add a click event listener to the randomize variable so that when the button it represents is clicked, the result() function is run. */
