History

ColdFusion 8:

  • Added support for the bind attribute in HTML format forms, including the bindAttribute, bindOnLoad, and onBindError attributes.

  • Added support for tool tips in HTML format, including the sourceForTooltip attribute.

  • Added support for a rich text editor in HTML format, including the richtext, basepath, fontFormats, fontNames, fontSizes, skin, stylesXML, templatesXML, toolbar, and toolbarOnFocus attributes and support for the height and width attributes.

    ColdFusion MX 7: Added this tag.

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.

Note: 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

Format

Default

Description

name

Required;

All

Name of the cftextinput control.

basepath

Optional; HTML

/CFIDE/scripts/ajax/FCKEditor

Path to the directory that contains the rich text editor. The editor configuration files are at the top level of this directory.

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

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.

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

stylesXML

Optional; HTML

/CFIDE/scripts/ajax/FCKEditor/fckstyles.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 fckeditor.html file, normally cf_webRoot/CFIDE/scripts/ajax/FCKeditor/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 the Developing ColdFusion Applications.

secureUpload

Optional

true

If true, enables secure upload using FCKeditor.

For secure upload, you must have sessionManagement set to yes. Secure upload does not work if sessionManagement is set to false.

If you do not use FCKeditor, Adobe recommends that you set config.enabled=false in the config.cfm available in the FCKeditor folder in cf_webRoot.

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 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 <cftextareaname="description"value="Enteradescription."/>.

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

Optional

All

  • 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 cftextareabind 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.

<cfform format="flash" height="300"> 
    <cfformitem type="text"> 
        Enter your name here</cfformitem> 
    <cftextarea name="userName" height="20" Width="500"/> 
    <cftextarea name="comment" html 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>
