Assume you are on a line of text and you enter /value. The cursor then moves to the line containing the string value. How can you tell the editor to the original line?
Event Listeners Return to the mas_register.js file in your editor. Directly below the initial comment section, insert an event listener for the window load event. Run an anonymous function in response to the event containing the following commands: Call the calcCart() function (which you will create shortly.) Create an onclick event handler for the regSubmit button that runs the sessionTest() function when the button is clicked. Create onblur event handlers for the input boxes with the ids: fnBox, lnBox, groupBox, mailBox, phoneBox, and banquetBox, running the calcCart() function in response to each event. Create an onchange event handler for the sessionBox selection list, running the calcCart() function when the selection list is changed.

• Created two dictionaries: • days, which uses the numbers 1-7 as the keys and "Sunday", "Monday",..."Saturday" as the values. • months, which uses the numbers 1-12 as the keys and "January", "February", ... "December" as the values. • Asked the user to enter a day (1-31), a month (1-12), a year, and a day of the week (1-7). You could assume the user entered valid numbers. Using the dictionaries, printed the date in the form "Monday, October 12, 2020" • Modify this program so that there is a function for each required input, that will test that the user has entered a valid number. • The function getting the month should accept any number between 1 and 12. • The function getting the day of the week should accept any number between 1 and 7. • The function getting the day of the month should test that the day is valid for a given month (pass the month to the function). For example, if month=-4 (April), 31 would not be accepted. • The function asking for the year should test for a…
