java.lang.Boolean |
getBrowserAutoCapitalize() |
java.lang.Boolean |
getBrowserAutoCorrect()
In Mobile Safari, should automatic correction be offered for text in the item's text box? If
null , then
Mobile Safari determines automatically whether to enable autocorrect. |
java.lang.Boolean |
getChangeOnKeypress()
Should this form item fire its
change handler
(and store its value in the form) on every keypress? Set to false to suppress the 'change' handler firing
(and the value stored) on every keypress. |

getEnteredValue()
Returns the raw text value that currently appears in the text field, which can differ from
FormItem.getValue() in various cases - for example:
for items that constrain the value range, such as a DateItem with
enforceDate :true, or a ComboBoxItem with addUnknownValues :false for items with
a defined valueMap or edit value formatter and parser functions which converts display value to data value
while the item has focus if changeOnKeypress is false |
java.lang.Boolean |
getEscapeHTML()
By default HTML characters will be escaped when
canEdit is false and readOnlyDisplay
is "static", so that the raw value of the field (for example "<b>AAA</b>" ) is displayed to the
user rather than the interpreted HTML (for example "AAA" ). |
java.lang.Boolean |

getPrintFullText()
When generating a print-view of the component containing this TextArea, should the form item expand to accommodate its
value? If set to false the text box not expand to fit its content in the print view, instead showing exactly as it does
in the live form, possibly with scrollbars.
|

fields such as TextItem

can detect the user editing the value via cut or paste interactions (triggered from keyboard shortcuts or the native
browser menu options) using the FormItem.isCutEvent()
and FormItem.isPasteEvent()
methods. This allows custom cut/paste handling to be added to the various change notification flow methods including
FormItem.change()

public void setUsePlaceholderForHint(boolean usePlaceholderForHint)
showing the hint in field
and if
supported by the browser, should the HTML5
placeholder
attribute
be used to display the hint within the field? If set to false
, then use of
the placeholder
attribute is disabled and an alternative technique to display
the hint in-field is used instead.
The HTML5 placeholder
attribute is supported in the following major browsers:
WebView
(used by the stock Browser app and when
packaging with PhoneGap
)In browsers other than the above, in-field hints are implemented via a different technique.
Note that placeholder behavior is known to differ in Internet Explorer and certain old
versions of the above browsers due to a recent change in the HTML5 specification regarding
the placeholder
attribute. Under the old rules, the placeholder is cleared
when the element is focused. In the latest HTML5 spec as published by WHATWG, the placeholder
is still displayed when the element is focused as long as the value is an empty string.
Browser | Pseudo-class or pseudo-element |
---|---|
Chrome, Safari | ::-webkit-input-placeholder |
Firefox 4 - 18 | :-moz-placeholder |
Firefox 19+ | ::-moz-placeholder |
Internet Explorer | :-ms-input-placeholder |
Note that unlike other browsers, Firefox 19+ applies opacity:0.4 to the placeholder text. See Bug 556145 - Placeholder text default style should use opacity instead of GrayText
Because browsers are required to ignore the entire rule if a selector is invalid, separate rules are needed for each browser. For example:
::-webkit-input-placeholder { color: blue; opacity: 1; } :-moz-placeholder { color: blue; opacity: 1; } ::-moz-placeholder { color: blue; opacity: 1; } :-ms-input-placeholder { color: blue; opacity: 1; }
If using Sass, it may be useful to utilize Sass' parent selector feature. For example:
.myCustomItem, .myCustomItemRTL, .myCustomItemDisabled, .myCustomItemDisabledRTL, .myCustomItemError, .myCustomItemErrorRTL, .myCustomItemFocused, .myCustomItemFocusedRTL, .myCustomItemHint, .myCustomItemHintRTL, .myCustomItemDisabledHint, .myCustomItemDisabledHintRTL { // ... &::-webkit-input-placeholder { color: blue; opacity: 1; } &:-moz-placeholder { color: blue; opacity: 1; } &::-moz-placeholder { color: blue; opacity: 1; } &:-ms-input-placeholder { color: blue; opacity: 1; } }
If using Compass, the
input-placeholder
mixin
that was added in version 1.0 can further simplify the code to style the placeholder text
For example:
.myCustomItem, .myCustomItemRTL, .myCustomItemDisabled, .myCustomItemDisabledRTL, .myCustomItemError, .myCustomItemErrorRTL, .myCustomItemFocused, .myCustomItemFocusedRTL, .myCustomItemHint, .myCustomItemHintRTL, .myCustomItemDisabledHint, .myCustomItemDisabledHintRTL { // ... @include input-placeholder { color: blue; opacity: 1; } }

In all browsers, clicking anywhere outside of the item causes the item to lose focus;
hence, in IE 6-9, this method will not work in other components' event handlers for certain events. For example, within
the click()
handler of a button, this item will have already
lost focus, so in IE 6-9, this method will return null if called within the button's click() handler. One cross-browser
solution to this issue is to save the selection range for later in a mouseDown()
or mouseOver()
handler.

Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.
