This element is created by setting the type attribute of a textbox to autocomplete. It is used to create a textbox with a popup containing a list of possible completions for what the user has started to type.

The autocomplete functionality is handled through one of more session objects, each of which can return a set of results given the current value of the textbox. The sessions can be set using the searchSessions attribute or by calling the addSession method.

autoFillAfterMatch Obsolete since Gecko 1.9.1
Type: boolean
If set to true, the entire text of the best match will be displayed at the end of the input. If false, only the text that hasn't been entered yet will be filled in. The textbox.autoFill attribute must be set to true to use this feature. As of Gecko 1.9.1, this attribute is superseded by the completedefaultindex attribute.
autofill New in Thunderbird 3 Requires SeaMonkey 2.0
Type: boolean
If set to true, the best match will be filled into the textbox as the user types. If false, the default, the value will not be filled in until the user selects an item.
completedefaultindex New in Thunderbird 3 Requires SeaMonkey 2.0

crop
Type: boolean
This attribute is not used and is only provided for compatibility with the menulist element.
disableAutocomplete Obsolete since Gecko 1.9.1
Type: boolean
If true, the autocomplete behavior will be disabled. You might use a script to change this attribute. If false, the default, autocomplete is enabled. As of Gecko 1.9.1, this attribute is now always specified in lower case.
disableautocomplete New in Thunderbird 3Requires SeaMonkey 2.0
Type: boolean
If true, the autocomplete behavior will be disabled. You might use a script to change this attribute. If false, the default, autocomplete is enabled.
disabled
Type: boolean
Indicates whether the element is disabled or not. If this attribute is set, the element is disabled. Disabled elements are usually drawn with grayed-out text. If the element is disabled, it does not respond to user actions, it cannot be focused, and the command event will not fire. In the case of form elements, it will not be submitted. Do not set the attribute to true, as this will suggest you can set it to false to enable the element again, which is not the case.
The disabled attribute is allowed only for form controls. Using it with an anchor tag (an <a> link) will have no effect.
The element will, however, still respond to mouse events. To enable the element, leave this attribute out entirely.
Visible controls have a disabled property which, except for menus and menuitems, is normally preferred to use of the attribute, as it may need to update additional state.

Note: Applies to: Thunderbird and SeaMonkey
If false, an arrow button will appear on the end of the textbox which will open a dropdown menu of all available results. The default value is true, hiding the dropdown button. This attribute only works correctly in SeaMonkey 1.x; for Thunderbird and SeaMonkey 2.0 you should also set the enablehistory attribute; as of Gecko 2.0 this attribute is completely superseded by it.
Note: For SeaMonkey 2.0 and all versions of Thunderbird prior to 3.0 you also need to provide the disablehistory attribute.

Overview

An onchange attribute is an event listener to the object for the Event change. A change event is fired in different ways for different XUL Input Elements as listed below:

onchange
Type: script code
TextBox When Enter key is pressed
Radio/Check Box When the state is changed
Select List When the selected item is changed

What is accessible

The script context at this point can only access the following things:

Example

<?xml version="1.0"?>
<?xml-stylesheet href="chrome://global/skin/" type="text/css"?>

<window
    id="findfile-window"

  <script type="text/javascript">
  function myFunction(e){
    /*
      Do something cool here or just say the below
    */
    alert(e.target.nodeName);
  }
  </script>
  <textbox id="find-text" onchange="return myFunction(event);"/>
</window>
onerrorcommand
Type: script code
This event handler is called when an error occurs when selecting a result from the popup.
oninput

Type: boolean
Note: Applies to: Thunderbird, SeaMonkey
If true, the popup will be shown. If false, the popup will not be shown, but the autocomplete results will still be available. You can set this to false and set the autoFill attribute to true to emulate a Communicator 4.x style autocomplete textbox. The default value is true.
size
Type: integer
The number of characters that can be displayed in the textbox.
tabindex

timeout
Type: integer
For autocomplete textboxes, the number of milliseconds before the textbox starts searching for completions. The default is 50 milliseconds. For search textboxes, the number of milliseconds before the timer fires a command event. The default is 500 milliseconds. For timed textboxes, the number of milliseconds before the timer fires a command event. There is no default. The timer starts after the user types a character. If the user types another character, the timer resets.
type
Type: one of the values below
You can set the type attribute to one of the values below for a more specialized type of textbox. Don't set the type if you wish to use a regular textbox.
autocomplete
A textbox that supports autocomplete. For more information about autocomplete textboxes, see the autocomplete documentation (XPFE [Thunderbird/SeaMonkey]) (Firefox)
number
 A textbox that only allows the user to enter numbers. In addition, arrow buttons appear next to the textbox to let the user step through values. There are several attributes that allow the number textbox to be configured, including decimalplaces, min, max, increment, wraparound, hidespinbuttons, and textbox.value.
password
A textbox that hides what is typed, used for entering passwords.
search
 A textbox intended for searching. The command event will fire as the user modifies the value. A listener for the command event should update search results. If the searchbutton attribute is set to true, the command event is only fired if the user presses the search button or presses the Enter key. You may specify grey text to appear when the search box is empty using the emptytext attribute, and a timeout may be set for the command event using the timeout attribute (defaults to 500).
timed
This textbox will fire a command event after the user types characters and a certain time has passed. The delay is set with the timeout attribute. The command event will fire if the user presses the Enter key. The timed type is deprecated in Gecko 1.9.1 and the search textbox may be used instead.
userAction
Type: one of the values below
This attribute will be set to the action the user is currently performing. Possible values:
none
The user is not interacting with the textbox.
typing
The user is typing into the textbox.
scrolling
The user is scrolling through the textbox.
value
Type: string
The string attribute allows you to associate a data value with an element. It is not used for any specific purpose, but you can access it with a script for your own use. Be aware, however, that some elements, such as textbox will display the value visually, so in order to merely associate data with an element, you could 1) Use another attribute like "value2" or "data-myAtt" (as in the HTML5 draft), as XUL does not require validation (less future-proof); 2) Use setAttributeNS() to put custom attributes in a non-XUL namespace (serializable and future-proof); 3) Use setUserData() (future-proof and clean, but not easily serializable). For user editable menulist elements, the contents, as visible to the user, are read and set using the Menulist.value syntax. For those elements, setAttribute("value", myValue) and getAttribute("value") do not access or affect the contents displayed to the user.
