Attributes

The following table lists attributes that ColdFusion uses directly. In HTML format, the tag also supports all HTML textarea tag attributes that are not on this list, and passes them directly to the browser.

Примечание.

Attributes that are not marked as All or XML are not handled by the skins provided with ColdFusion. They are, however, included in the generated XML.

Attribute	Req/Opt;Format	Default	Description
name	Required;All		Name of the cftextinput control.
basepath	Optional; HTML	cf_scripts/scripts/ajax /CKEditor	Path to the directory that contains the rich text editor. The editor configuration files are at the top level of this directory.Meaningful only if the richText attribute is true.
bind	Optional;Flash,HTML		A bind expression that dynamically sets an attribute of the control. For details, see Usage.
bindAttribute	Optional;HTML	value	Specifies the HTML tag attribute whose value is set by the bind attribute. You can only specify attributes in the browser's HTML DOM tree, not ColdFusion-specific attributes. Ignored if there is no bind attribute.
bindOnLoad	Optional;HTML	no	A Boolean value that specifies whether to execute the bind attribute expression when first loading the form. Ignored if there is no bind attribute.
disabled	Optional;All	not disabled	Disables user input, making the control read-only. To disable input, specify disabled without an attribute, or disabled="Yes" (or any ColdFusion positive Boolean value, such as True). To enable input, omit the attribute or specify disabled="No" (or any ColdFusion negative Boolean value, such as False).
enabled	Optional;Flash	yes	Boolean value that specifies whether the control is enabled. A disabled control appears in light gray. The inverse of the disabled attribute.
fontFormats	Optional; HTML	All valid formats	A comma-separated list of the font names to display in the rich text editor Formats selector. The formats specify the HTML tags to apply to typed or selected text. You can specify any subset of the following list: "p,div,pre,address,h1,h2,h3,h4,h5,h6".
fontNames	Optional; HTML	All valid font names	A comma-separated list of the font names to display in the rich text editor Font selector. You can specify any subset of the following list: "Arial,Comic Sans MS,Courier New,Tahoma,Times New Roman,Verdana".
FontSizes	Optional; HTML	See Description	A comma-separated list of the font sizes to display in the rich text editor Size selector. List entries must have the format of numeric font size/descriptive text. For example, to display the text "small font" to indicate a font size of 1, specify "1/small font". By default, the following values appear in the selector: 1/xx-small,2/x-small,3/small,4/medium,5/large,6/x-large,7/xx-large.
height	Optional;Flash,HTML		In Flash forms, height of the control, in pixels. In HTML forms, this attribute has an effect only if you specify richtext="true"; in this case, it is the height, in pixels, of the control, including the control bar and text box.
html	Optional;Flash	no	Boolean value that specifies whether the text area contains HTML.
label	Optional;Flash and XML		Label to put beside the control on a form.
maxLength	Optional;All		The maximum length of text that can be entered. ColdFusion uses this attribute only if you specify maxlength in the validate attribute.
message	Optional;All		Message text to display if validation fails.
onBindError	Optional;HTML	See Description	The name of a JavaScript function to execute if evaluating a bind expression results in an error. The function must take two attributes: an HTTP status code and a message. (The status code is -1 if the error is not an HTTP error.)If you omit this attribute, and have specified a global error handler (by using the ColdFusion.setGlobalErrorHandler function), it displays the error message; otherwise a default error pop-up displays.
onChange	Optional;All		JavaScript (HTML/XML) or ActionScript (Flash) to run when the control changes due to user action.
onClick	Optional;HTML and XML		JavaScript to run when the user clicks the control.
onError	Optional;HTML and XML		Custom JavaScript function to execute if validation fails.
onKeyDown	Optional;All		JavaScript (HTML/XML) or ActionScript (Flash) ActionScript to run when the user presses a keyboard key in the control.
onKeyUp	Optional;All		JavaScript (HTML/XML) or ActionScript (Flash) to run when the user releases a keyboard key in the control.
onMouseDown	Optional;All		JavaScript (HTML/XML) or ActionScript (Flash) to run when the user releases a mouse button in the control.
onMouseUp	Optional;All		JavaScript (HTML/XML) or ActionScript (Flash) to run when the user presses a mouse button in the control.
onValidate	Optional;HTML and XML		Custom JavaScript function to validate user input. The JavaScript DOM form object, input object, and input object value are passed to the function, which must return True if validation succeeds, False otherwise. If you specify this attribute, ColdFusion ignores the validate attribute.
pattern	Required if {{validate = "regular_ expression"}}HTML and XML.		JavaScript regular expression pattern to validate input. Omit leading and trailing slashes. ColdFusion uses this attribute only if you specify regex in the validate attribute. For examples and syntax, see Building Dynamic Forms with cfform Tags in the Developing ColdFusion Applications.
range	Optional;All		Minimum and maximum allowed numeric values. ColdFusion uses this attribute only if you specify range in the validate attribute. If you specify a single number or a single number followed by a comma, it is treated as a minimum, with no maximum. If you specify a comma followed by a number, the maximum is set to the specified number, with no minimum.
required	Optional;All	no	yes: the field must contain text. no: the field can be empty.
richText	Optional; HTML	no	A Boolean value specifying whether this control is a rich text editor with tool bars to control the text formatting. For detailed information on using the rich text editor, see Using the rich text editor in Using Ajax form controls and features in the Developing ColdFusion Applications.
skin	Optional; HTML	default	Specifies the skin to be used for the rich text editor. By default, the valid values are default, silver, and office2003. You can also create custom skins that you can then specify in this attribute. For more information, see Using the rich text editor in Using Ajax form controls and features in the Developing ColdFusion Applications.
sourceForTooltip	Optional; HTML		The URL of a page to display as a tool tip . The page can include CFML and HTML to control the contents and format, and the tip can include images. If you specify this attribute, an animated icon appears with the text "Loading..." while the tip is being loaded.
style	Optional;All		In HTML or XML format forms, ColdFusion passes the style attribute to the browser or XML. In Flash format forms, must be a style specification in CSS format, with the same syntax and contents as used in Flex for the corresponding Flash element.
stylesXML	Optional; HTML	/cfusion/wwwroot/ cf_scripts/scripts/ajax /CKEditor / ckstyles .xml	The path of the file that defines the styles in the rich text editor Styles selector. Relative paths start at the directory that contains the ckeditor.html file, normally cf_webRoot/cf_scripts/ajax/CKeditor/editor. You can specify an absolute path starting at the web root, such as /myApps/RTEeditor.mystyles.xml. For information on configuring styles, see Using the rich text editor in Using Ajax form controls and features in the Developing ColdFusion Applications.
templatesXML	Optional; HTML	/cfusion/wwwroot/ cf_scripts/scripts/ajax /CKEditor / cktemplates .xml	The path of the file that defines the templates that are displayed when you click the rich text editor Templates icon. For path details, see stylesXML. For information on configuring templates, see Using the rich text editor in the Developing ColdFusion Applications.
toolbar	Optional; HTML	Default	Specifies the rich text editor toolbar. By default, the valid values for this attribute are: Default, a complete set of controls, and Basic, a minimal configuration. You can add configurations; for details see Using the rich text editor in Using Ajax form controls and features in the Developing ColdFusion Applications. Note: This attribute's value is case sensitive.
toolbarOnFocus	Optional; HTML	no	A Boolean value that specifies whether the rich text editor toolbar expands and displays its controls only when the rich text editor has the focus.
tooltip	Optional; Flash, HTML		Text to display when the mouse pointer hovers over the control. Can include HTML formatting. Ignored if you specify a sourceForTooltip attribute.
validate	Optional;All		The type or types of validation to perform. Available validation types and algorithms depend on the format. For details, see the Usage section of the cfinput tag reference.
validateAt	Optional;HTML and XML	onSubmit	How to do the validation; one or more of the following: onSubmit onServer onBlur For Flash format forms, onSubmit and onBlur are identical; for both, validation is done when the user submits the form. For multiple values, use a comma-delimited list. For details, see the Usage section of the cfinput tag reference.
value	Optional;All		Initial value to display in text control. You can specify an initial value as an attribute or in the tag body, but not in both places. If you specify the value as an attribute, put the closing cftextarea tag immediately after the opening cftextarea tag, with no spaces or line feeds between, or place a closing slash at the end of the opening cftextarea tag; for example <cftextarea name="description" value="Enter a description." />.
visible	Optional;Flash	yes	Boolean value that specifies whether to show the control. Space that would be occupied by an invisible control is blank.
width	Optional;Flash,HTML		The width of the control, in pixels. In HTML forms, this attribute has an effect only if you specify richtext="true".
wrap	OptionalAll		hard: wraps long lines, and sends the carriage return to the server. off: does not wrap long lines. physical: wraps long lines, and transmits the text at all wrap points. soft: wraps long lines, but does not send the carriage return to the server. virtual: wraps long lines, but does not send the carriage return to the server.

Usage

For this tag to work properly in HTML format. the browser must be JavaScript-enabled.
If you put text in the tag body, the control displays all text characters between the cftextarea opening and closing tags; therefore, if you use line feeds or white space to format your source text, they appear in the control. If the cfform preserveData attribute is "yes", and the form posts back to the same page, the posted value (not the value of the value attribute) of the cftextinput control is used.

Validation

For a detailed description of the validation attribute and the types of validation supported by ColdFusion, see the Usage section of the cfinput tag reference. For more details on ColdFusion validation techniques, see Validating data in the Developing ColdFusion Applications.

Flash form data binding

The bind attribute lets you populate form fields using the contents of other form fields. To specify text from another Flash form field in a cftextarea bind attribute, use the following format:{sourceTagName.text}For example, the following line uses the value of the text that the user enters in the from the userName field in the greeting in the comment text box. The user can change or replace this message with a typed entry.

<cfformitem type="text">
Enter your name here</cfformitem>
<cftextarea name="userName" height="20" Width="500"/>
<cftextarea name="comment" height="100" Width="500"
bind="Hello {userName.text}! Enter your comments here." />
</cfform>

HTML form data binding

The bind attribute lets you set any cftextarea attribute dynamically from the value of another form control or by calling a CFC or JavaScript function. By default it sets the control's value attribute, but you can specify a different attribute to set by using the bindAttribute attribute. For more information on binding, see Binding data to form fields in the Developing ColdFusion Applications.

Example

This example has two cftextarea controls. When you submit the form, ColdFusion copies the text from the first control into the second. The onBlur maxlength validation prevents you from entering more than 100 characters. The > character that closes the cftextarea opening tag, the text in the tag body, and the cftextarea closing tag are on a single line to ensure that only the desired text displays, but the line is split in this example for formatting purposes.

<h3>cftextarea Example</h3> 
<cfparam name="text2" default=""> 
<cfif isdefined("form.textarea1") AND (form.textarea1 NEQ "")> 
<cfset text2=form.textarea1> 
</cfif> 

<cfform name="form1"> 
<cftextarea name="textarea1" wrap="virtual" rows="5" cols="25" 
validate="maxlength" validateAt="onBlur" maxlength="100" 
>Replace this text. Maximum length is 100 Characters, and this text is
currently 99 characters long.</cftextarea> 
<cftextarea name="textarea2" wrap="virtual" rows="5" cols="50" value="#text2#" /><br><br> 
<input type="submit" value="submit field"><br> 
</cfform>
