The JTextArea class provides a component that displays multiple lines of text and optionally allows the user to edit the text. If you need to obtain only one line of input from the user, you should use a text field.If you want the text area to display its text using multiple fonts or other styles, you should use an editor pane or text pane.If the displayed text has a limited length and is.

Bootstrap Textarea IntroIn the pages we create we use the form elements in order to collect some information from the visitors and return it back to the site owner serving various purposes. To do it properly – meaning getting the right answers, the right questions should be asked so we architect out structure carefully, thinking of all the possible cases and types of information needed and possibly provided.But no matter how precise we are in this, there always are some cases when the information we need from the user is rather blurry before it gets actually provided and needs to spread over much more than just the regular a single or a few words generally filled in the input fields. That’s where the element comes in – it’s the only and irreplaceable element in which the visitors can freely write back some sentences providing a feedback, sharing a reason for their actions or just a few thoughts to hopefully aid us making the product or service the page is about even better.

The first example shows the most simple usage, with only an id attribute to allow the to be associated with a element for accessibility purposes, and a name attribute to set the name of the associated data point submitted to the server when the form is submitted.The second example show some more complex features:. The rows and cols attributes allow you to specify an exact size for the to take.
Setting these is a good idea for consistency, as browser defaults can differ. maxlength specifies a maximum number of characters that the is allowed to contain. You can also set a minimum length that is considered valid using the minlength attribute, and specify that the will not submit (and is invalid) if it is empty, using the required attribute. This provides the with simple validation, which is more basic than the other form elements (for example, you can't provide specific regexs to validate the value against using the pattern attribute, like you can with the element). wrap specifies the wrapping behavior of the text when it reaches the edge of the. If you want default content for your, you enter it between the opening and closing tags. Does not support the value attribute.The element also accepts several attributes common to form s, such as autocomplete, autofocus, disabled, placeholder, readonly, and required.
AttributesThis element includes the. Autocapitalize This is a non-standard attribute supported by WebKit on iOS (therefore nearly all browsers running on iOS, including Safari, Firefox, and Chrome), which controls whether and how the text value should be automatically capitalized as it is entered/edited by the user.
The non-deprecated values are available in iOS 5 and later. Possible values are:. none: Completely disables automatic capitalization. sentences: Automatically capitalize the first letter of sentences. words: Automatically capitalize the first letter of words.
characters: Automatically capitalize all characters. on: Deprecated since iOS 5. off: Deprecated since iOS 5.autocomplete This attribute indicates whether the value of the control can be automatically completed by the browser. Possible values are:. off: The user must explicitly enter a value into this field for every use, or the document provides its own auto-completion method; the browser does not automatically complete the entry. on: The browser can automatically complete the value based on values that the user has entered during previous uses.If the autocomplete attribute is not specified on a element, then the browser uses the autocomplete attribute value of the element's form owner.
The form owner is either the element that this element is a descendant of or the form element whose id is specified by the form attribute of the input element. For more information, see the attribute in.
Autofocus This Boolean attribute lets you specify that a form control should have input focus when the page loads. Only one form-associated element in a document can have this attribute specified. Cols The visible width of the text control, in average character widths. If it is specified, it must be a positive integer. If it is not specified, the default value is 20. Disabled This Boolean attribute indicates that the user cannot interact with the control. If this attribute is not specified, the control inherits its setting from the containing element, for example; if there is no containing element when the disabled attribute is set, the control is enabled.
Form The form element that the element is associated with (its 'form owner'). The value of the attribute must be the id of a form element in the same document. If this attribute is not specified, the element must be a descendant of a form element. This attribute enables you to place elements anywhere within a document, not just as descendants of form elements. Maxlength The maximum number of characters (unicode code points) that the user can enter. If this value isn't specified, the user can enter an unlimited number of characters.
Minlength The minimum number of characters (unicode code points) required that the user should enter. Name The name of the control. Placeholder A hint to the user of what can be entered in the control. Carriage returns or line-feeds within the placeholder text must be treated as line breaks when rendering the hint. Note: Placeholders should only be used to show an example of the type of data that should be entered into a form; they are not a substitute for a proper element tied to the input.
See in for a full explanation. Disabled and readonlyThis example shows two s — one of which is disabled, and one of which is readonly. Have a play with both and you'll see the difference in behavior — the disabled element is not selectable in any way (and its value is not submitted), whereas the readonly element is selectable and its contents copyable (and its value is submitted); you just can't edit the contents. Note: In browsers other than firefox, such as chrome, the disabled textarea content may be selectable and copyable.
