In this exercise, you’ll use radio buttons to determine whether the conversion is from Fahrenheit to Celsius or vice versa. You’ll also modify the DOM so the labels change when a radio button is clicked, and the page displays an error message when the user enters invalid data.
2. Note that the JavaScript file has some starting JavaScript code, including the $() function, three helper functions, three event handler functions, and a DOMContentLoaded event handler that attaches the three event handlers.
3. Review how the toCelsius() and toFarhenheit() event handler functions call the toggleDisplay() helper function and pass it strings to display. Also note that the toggleDisplay() helper function and the convertTemp() event handler function are incomplete.
4. Code the toggleDisplay() function so it changes the text in the labels for the text boxes to the values in the parameters that it receives. It should also clear the disabled text box where the computed temperature is displayed.

Randomly choose one of the RadioButtons as the winning button. When the user clicks a RadioButton, display a message indicating whether the user is right. Add a Label to the Form that provides a hint. When the users mouse hovers over the label, notify the user of one RadioButton that is incorrect.

Listen for the click event. The button should change the text content of the paragraph with an id of "p2" to: "This button toggles text content." If the button is clicked a 2nd time, the text content should change back to: "Paragraph Two."The button should switch the text back and forth, so 3rd and 4th clicks willdo the same, etc. NOTE: Questions 2 and 5 are about toggling. While Part 1 is wrong, Part 2 will be correct. This is not an error. You should try to make both parts correct.arrow_forward
