HTML5 New Form Attributes-Part 3

Formmethod Attribute

 
A string indicating which HTTP method (GET or POST) should be used when submitting; it overrides the method of the <form> element if defined. The formmethod only applies when the type is an image or submit, and the form attribute has been set.
 
If the input element is a submit button or image, this attribute specifies the HTTP method that the browser uses to submit the form. Possible values are:
  • post: The data from the form is included in the body of the form and is sent to the server.
  • get: The data from the form are appended to the form attribute URI, with a "?" as a separator, and the resulting URI is sent to the server. Use this method when the form has no side-effects and contains only ASCII characters.
Purpose: If specified, this attribute overrides the method attribute of the form element.
 
Note: This attribute is supported on input and button elements.
 
Syntax
 
<input type="submit" value="Submit" formmethod="POST">
 
Browser Support
 
It is supported in all major browsers such as Chrome, Safari, Internet Explorer, Firefox and Opera.

When To use the novalidate attribute and Formnovalidate Attribute

The formnovalidate attribute gives you a finer degree of control because it applies only when that particular button is clicked.

<input type="submit" formnovalidate value="Don't validate">
