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.
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.

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. |

Optional;All |
no |
|
richText |
Optional; HTML |

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 |
/ cktemplates .xml |

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. |
wrap |
OptionalAll |
|

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>
