1. Develop, test and validate an HTML document that collects the following information from the user: last name, first name, middle initial, age (restricted to be greater than 17), and weight (restricted to the range of the 800-300). You must have event handlers for the form elements that collect this information that check the input data for correctness. Messages in alert windows must be produced when errors are detected2. Develop, test, and validate an HTML document that has checkboxes for apple (59 cents each), orange (49 cents each), and banana (39 cents each), along with a Submit button. Each of the checkboxes should have its own onclick event handler. These handlers must add the cost of their fruit to a total cost. An event handler for the Submit button must produce an alert window with the message “Your total cost is: $xxx,” where xxx is the total cost of the chosen fruit, including 5 percent for sales tax. This handler must return false ( to avoid actual submission of the form data).3. Write a script that inputs a telephone number as a string in the form (852) 2209 7760. The script should use String method split to extract the area code as a token, the first four digits of the phone number as a token and the last four digits of the phone number as a token. Display the area code in one text field and the eight-digit phone number in another text field.4. Write a script that uses random number generation to create sentences. Use four arrays of strings called article, noun, verb and preposition. Create a sentence by selecting a word at random from each array in the following order: article, noun, verb, preposition, article and noun. As each word is picked, concatenate it to the previous words in the sentence. The words should be separated by spaces. When the final sentence is output, it should start with a capital letter and end with a period.For examples:The arrays should be filled as follows: the article array should contain the articles “the”, “a”, “one”, “some” and “any”; the noun array contain the noun “boy”, “girl”, “dog”,”town” and “car”; the verb array should contain the verbs “drove”, “jumped”,”ran”,”walked” and “skipped”; the preposition array should contain the prepositions “to”, “from”, “over”, “under” and “on”.
