The DOM Input Search autocomplete Property in HTML DOM is used to set or return the value of the autocomplete attribute of an Input search field. The autocomplete attribute is used to specify whether the autocomplete attribute has “on” or “off” value. When the autocomplete attribute is set to on, the browser will automatically complete the values based on which the user entered before. 

Syntax: 

  • It returns the Input search autocomplete property.
searchObject.autocomplete
  • It is used to set the Input search autocomplete property.
searchObject.autocomplete = "on|off"

Property Values: 

  • on: It is the default value. It automatically completes the values.
  • off: It defines that the user should fill the values of the search input field. It does not automatically complete the values.

Return Value: It returns a string value which represents the state of autocomplete 

Example: This Example illustrates how to return the property.
