Definition and Usage
The formMethod property sets or returns the value of the formmethod attribute of a submit button.
The formmethod attribute defines the HTTP method for sending form-data to the action URL.
The formmethod attribute overrides the method attribute of the <form> element.
The formmethod attribute is only used for buttons with type="submit".
The form-data can be sent as URL variables (method="get") or as an HTTP post transaction (method="post").
Notes on the "get" method:
- it appends the form-data to the URL in name/value pairs
- it is useful for form submissions where a user want to bookmark the result
- There is a limit to how much data you can place in a URL (varies between browsers), therefore, you cannot be sure that all of the form-data will be correctly transferred
- Never use the "get" method to pass sensitive information! (password or other sensitive information will be visible in the browser's address bar)
Notes on the "post" method:
- it sends the form-data as an HTTP post transaction
- Form submissions with the "post" method cannot be bookmarked
- it is more robust and secure than "get"
- it does not have size limitations
Note: The formmethod attribute is new for the <input> element with type="submit" in HTML5.
The formMethod property is supported in all major browsers.
Note: The formMethod property is not supported in Internet Explorer 9 and earlier versions.
