Mozilla XUL Element and Script Reference

Contents  Quick Reference

Button

A button that can be pressed by the user. Event handlers can be used to trap mouse, keyboard and other events. It is typically rendered as a grey outset rectangle. You can specify the label of the button using the label attribute or by placing content inside the button.

Example:

    <button label="Press Me"
            oncommand="alert('You pressed me!'); return false;"/>

Attributes:

Attributes inherited from XUL Element

accesskey

This should be set to a letter that is used as a shortcut key. This letter should be one of the characters that appears in the label text for the button. This letter will typically be drawn underlined, although this behavior will be platform and skin specific. When the user presses ALT (or a similar key that varies on each platform) and the access key, the button will be activated from anywhere in the window.

autoCheck    Moz0.9.5
checkState    Moz0.9.5
checked    Moz0.9.5

Indicates whether the button is checked or not.

command

Set to an id of a command element that is being observed by the element.

crop

If the label of the button is too small to fit in its given space, the text will be cropped on the side specified by the crop attribute. An ellipsis will be placed in place of the cropped text. If the box direction is right to left (rtl), the cropping is reversed.

dir

Specifies which side of the button's label that its image is placed.

If this attribute is set to true, the button is disabled. This is usually drawn with the text in grey. If the button is disabled, the function of the button cannot be performed. Leave the attribute out entirely for a regular enabled button.
