! Introduction
|
|
|
|
The edit text widget provides a user interface in the browser for editing text tiddler fields. The editing element is dynamically bound to the underlying tiddler value: changes to the tiddler are instantly reflected, and any edits are instantly propagated.
|
|
|
|
By default, applying the EditTextWidget to the `text` field of a tiddler will generates an HTML `<textarea>` element, i.e. a multi-line editor. Applying the EditTextWidget to any other field generates an HTML `<input type="text">` element, a single-line editor. This behaviour can be overridden with the `tag` and `type` attributes.
|
|
|
|
! Content and Attributes

|
The content of the `<$edit-text>` widget is ignored.

! Examples
|
|
|
|
If you wanted to change the field //myconfig// of the tiddler //AppSettings//, you could use an EditTextWidget to edit the field, and then show the result anywhere else by using `{{AppSettings!!myconfig}}`. Note that this will create tiddler AppSettings if it doesn't already exist.
|
|
|
|
<$macrocall $name=".example" n="1"
|
|
eg="""<$edit-text tiddler="AppSettings" field="myconfig"/><p/>
|
|
Value of ''myconfig'' : {{AppSettings!!myconfig}}
|
|
"""/>
|
|
|
|
!! Text Selection
|
|
|
|
If the edit field already contains text or a default value is provided, you can use the `focusSelectFromStart` and `focusSelectFromEnd` attributes to only select part of the text when using `focus="yes"`.
|
|
|
|
Partial selection when editing this tiddler's //caption// field:
|
|
|
|
<$macrocall $name=".example" n="2"
|
|
eg="""<$edit-text tiddler=<<currentTiddler>> field="caption" focus="yes" focusSelectFromStart="5" />
|
|
"""/>
|
|
|
|
!!! {{!!heading}}
|
|
|
|
Provide a dated heading for this example where only the placeholder (but not the date) is selected for easier text input:
|
|
|
|
<$macrocall $name=".example" n="3"
|
|
eg="""<$edit-text tiddler=<<currentTiddler>> field="heading" size="25" focus="yes" focusSelectFromEnd="13" default={{{ [[Heading Text (]] [<now YYYY-0MM-0DD>] [[)]] +[join[]] }}} />
|
|
"""/>
|
|
|
|
!!! Input Actions, with class attribute
|
|
|
|
<$macrocall $name=".example" n="4"
|
|
eg="""\procedure onInput()
|
|
<%if [get[temp]match[$:/]] %>
|
|
<$action-confirm $message="Yes, this is how system tiddler names begin!"/>
|
|
<% endif %>
|
|
\end
|
|
|
|
Type a new tiddler name, starting with the system prefix `$:/`: <$edit-text inputActions=<<onInput>> field="temp" class="tc-edit-texteditor"/>
|
|
|
|
"""/>
