We use jQuery serialize() method to take data from tag, by calling serialize(), complete data of form comes in URL form. It takes data from input, textarea, select tags and converts it to URL format. It is used in Ajax. So that the data can be sent easily. Earlier we had to take data one by one from the form tag.
Syntax:
$ (selector).serialize()
return the form data in URL form
