Using HTML 'checkbox' Input Fields


How To Use "checkbox" Input Fields?



A "checkbox" input field is defined as <input type="checkbox" .../>. A "checkbox" input field can be used to create a checkbox to allow viewers to switch on or off a boolean flag. There are other attributes you may need to use for a "checkbox" input field:

  • name="fieldName" - Specifies the name of this field.
  • value="selectedValue" - Specifies the value to be used when this checkbox is selected. The default is value="on".
  • checked="checked" - Specifies that this checkbox is checked by default.

Here is a tutorial example with three checkbox input fields:

<?xml version="1.0" ?>

   <input type="submit" value="Submit"/>
