button_tag(content_or_options = nil, options = nil, &block) public

Creates a button element that defines a submit button, reset button or a generic button which can be used in JavaScript, for example. You can use the button tag as a regular submit tag but it isn’t supported in legacy browsers. However, the button tag does allow for richer labels such as images and emphasis, so this helper will also accept a block. By default, it will create a button tag with type submit, if type is not given.

Options

  • :data - This option can be used to add custom data attributes.

  • :disabled - If true, the user will not be able to use this input.

  • Any other key creates standard HTML options for the tag.

Data attributes

  • confirm: 'question?' - If present, the unobtrusive JavaScript drivers will provide a prompt with the question specified. If the user accepts, the form is processed normally, otherwise no action is taken.

  • :disable_with - Value of this parameter will be used as the value for a disabled version of the submit button when the form is submitted. This feature is provided by the unobtrusive JavaScript driver.
