I have a project, that need to submit two sets of data to the server，Name Date，Phone number Date.But I don’t know how to realize the function of the submitted data.
Requirements of the project:
1.name and telephone number can not be empty.
2.If the data is empty to error prompt, and enter again.
3.The background service personnel need to be able to read your code.
Here is a Demo, hoping to get help.
