You are validating user input by using JavaScript and regular expressions.
A group of predefined regular expressions will validate two input fields:
✑ An email address in a function named validateEmail (for example, [email protected])
✑ A nine-digit number that allows optional hyphens after the second and fifth character in a function named validateSSN(for example, 555555555 or 555-55-
5555)
You need to use the correct expression to validate the input.
Which expression should you insert into each function? (To answer, drag the appropriate regular expression statement to the correct location. Each regular expression statement may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)

Correct Answer:
* The serialize() method creates a URL encoded text string by serializing form values.
You can select one or more form elements (like input and/or text area), or the form element itself.
The serialized values can be used in the URL query string when making an AJAX request.
Example: $("form").serialize());
* decodeURIComponent
The decodeURIComponent() function decodes a URI component.
Return Value: A String, representing the decoded URI
Incorrect Answers:
Not decodeURI:
decodeURI is intended for use on the full URI.
decodeURIComponent is intended to be used on .. well .. URI components that is any part that lies between separators (; / ? : @ & = + $ , #).
