I have created some html and style docs from my own work in my coding program that displays: Data Revise Customer Enter name Country Choose a country Status Order Date mm/dd/yyyy Pending processing O Shipped Submit Id Clear form 1 Date Sep 12, 2 Sep 20, 2 Oct 3, 20 Oct 8, 20 Oct 10, 20 Customer Orders Country Progress I need help improving the section with Customer, Country, and Status data. These are the requirements: Status Shipped Shipped Processing Pending Pending
I need help improving the section with Customer, Country, and Status data. These are the requirements: • Add an event listener to ensure all the data are entered when clicking the Submit button (include the OK button box as well) • Show the message if there is no data Requirements of messages to show (all need to be met): (When click Submit but nothing is entered in the Customer field) This Page Says Please enter a name
● (When click Submit but nothing is entered in the Country field) This Page Says Please choose a country (When click Submit but nothing is entered in the Status field) This Page Says Please choose a status If you need me to reformat the question, please ask before flagging. I just need help in learning how to get it to respond the way I asked above, for I am struggling to learn the concept. answers prohibits third-party us and I am not trying to violate any rules. Thus, I marked off names where it should be and made sure my codes don't have any urls whatsoever. Please note this is a technical assignment and the fonts that appear in my codes is through use of coding recognition. No links are appearing nor there are yrs. Thank you in advance, sincerely! Please provide the codes only. Outputs shown in answer if possible. Names can be rearranged and will help me learn how it fits into place.
