Providing submit buttons

Important Information about Techniques

See Understanding Techniques for WCAG Success Criteria for important information about the usage of these informative techniques and how they relate to the normative WCAG 2.1 success criteria. The Applicability section explains the scope of the technique, and the presence of techniques for a specific technology does not imply that the technology can be used in all situations to create content that meets WCAG 2.1.


Content that includes form controls.

This technique relates to Success Criterion 3.2.2: On Input (Sufficient as a way to meet G80: Providing a submit button to initiate a change of context).


The objective of this technique is to provide a mechanism that allows users to explicitly request changes of context. The intended use of a submit button is to generate an HTTP request that submits data entered in a form, so it is an appropriate control to use for causing a change of context.


Example 1

This is a basic example of a form with a submit button.

<form action="" method="post"><br /> 
 <p>Enter your e-mail address to subscribe to our mailing list.</p><br /> 
 <label for="address">Enter email address:</label><input type="text" 
 id="address" name="address" /> 
 <input type="submit" value="Subscribe" /><br /> 

Example 2

The following example uses a server-side script (specified in the action attribute) that redirects the user to the requested page.

 <form action="" method="get"><br /> 
    <p>Navigate the site.</p><br /> 
    <select name="dest"><br /> 
      <option value="/index.html">Home</option/><br /> 
      <option value="/blog/index.html">My blog</option/><br /> 
      <option value="/tutorials/index.html">Tutorials</option/><br /> 
      <option value="/search.html">Search</option/><br /> 
    </select><br /> 
  <input type="submit" value="Go to Page" /><br />
