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 propogated.
By default, the edit text widget generates a <textarea> as the HTML editing element when the text field is edited, and a <input type="text"> element otherwise. This behaviour can be overridden with the tag and type attributes.
Content and Attributes
The content of the <$edit-text> widget is ignored.
| Attribute | Description |
|---|---|
| tiddler | The tiddler to edit (defaults to the CurrentTiddler) |
| field | The field to edit (defaults to text). Takes precedence over the index attribute |
| index | The index to edit |
| default | The default text to be provided when the target tiddler doesn't exist |
| class | A CSS class to be assigned to the generated HTML editing element |
| placeholder | Placeholder text to be displayed when the edit field is empty |
| focusPopup | Title of a state tiddler for a popup that is displayed when the editing element has focus |
| tag | Overrides the generated HTML editing element tag. Use textarea for a multi-line editor |
| type | Overrides the generated HTML editing element type attribute |
| size | The size of the input field (in characters) |
| autoHeight | Either "yes" or "no" to specify whether to automatically resize textarea editors to fit their content (defaults to "yes") |
| minHeight | Minimum height for automatically resized textarea editors, specified in CSS length units such as "px", "em" or "%" |
Notes
One trap to be aware of is that the edit text widget cannot be used to edit a field of the tiddler that contains it. Each keypress results in the tiddler being re-rendered, which loses the cursor position within the text field.
Instead, place the edit text widget in a template that references the tiddler you want to modify.
For example, if you wanted to edit the value of the "myconfig" field of the tiddler "AppSettings", you might do so by creating a separate tiddler "ChangeAppSettings" that contains the following:
<$edit-text tiddler="AppSettings" field="myconfig"/>
