Method Details

as

public static InputElement as(Element elem)

Assert that the given Element is compatible with this class and automatically typecast it.

is

public static boolean is(JavaScriptObject o)

Determines whether the given JavaScriptObject can be cast to this class. A null object will cause this method to return false.

is

public static boolean is(Node node)

Determine whether the given Node can be cast to this class. A null node will cause this method to return false.

is

public static boolean is(Element elem)

Determine whether the given Element can be cast to this class. A null node will cause this method to return false.

click

public final void click()

Simulate a mouse-click. For INPUT elements whose type attribute has one of the following values: "button", "checkbox", "radio", "reset", or "submit".

getAccept

public final String getAccept()

A comma-separated list of content types that a server processing this form will handle correctly.

See Also:

• W3C HTML Specification

getAccessKey

public final String getAccessKey()

A single character access key to give access to the form control.

See Also:

• W3C HTML Specification

getAlt

public final String getAlt()

Alternate text for user agents not rendering the normal content of this element.

See Also:

• W3C HTML Specification

getDefaultValue

public final String getDefaultValue()

When the type attribute of the element has the value "text", "file" or "password", this represents the HTML value attribute of the element. The value of this attribute does not change if the contents of the corresponding form control, in an interactive user agent, changes.

See Also:

• W3C HTML Specification

getForm

public final FormElement getForm()

Returns the FORM element containing this control. Returns null if this control is not within the context of a form.

getMaxLength

public final int getMaxLength()

Maximum number of characters for text fields, when type has the value "text" or "password".

See Also:

• W3C HTML Specification

getName

public final String getName()

Form control or object name when submitted with a form.

See Also:

• W3C HTML Specification

getSize

public final int getSize()

Size information. The precise meaning is specific to each type of field.

See Also:

• W3C HTML Specification

getSrc

public final String getSrc()

When the type attribute has the value "image", this attribute specifies the location of the image to be used to decorate the graphical submit button.

See Also:

• W3C HTML Specification

getType

public final String getType()

The type of control created (all lower case).

See Also:

• W3C HTML Specification

getValue

public final String getValue()

When the type attribute of the element has the value "text", "file" or "password", this represents the current contents of the corresponding form control, in an interactive user agent. Changing this attribute changes the contents of the form control, but does not change the value of the HTML value attribute of the element. When the type attribute of the element has the value "button", "hidden", "submit", "reset", "image", "checkbox" or "radio", this represents the HTML value attribute of the element.

See Also:

• W3C HTML Specification

isChecked

public final boolean isChecked()

When the type attribute of the element has the value "radio" or "checkbox", this represents the current state of the form control, in an interactive user agent. Changes to this attribute change the state of the form control, but do not change the value of the HTML checked attribute of the INPUT element. Note: During the handling of a click event on an input element with a type attribute that has the value "radio" or "checkbox", some implementations may change the value of this property before the event is being dispatched in the document. If the default action of the event is canceled, the value of the property may be changed back to its original value. This means that the value of this property during the handling of click events is implementation dependent.

isDefaultChecked

public final boolean isDefaultChecked()

When type has the value "radio" or "checkbox", this represents the HTML checked attribute of the element. The value of this attribute does not change if the state of the corresponding form control, in an interactive user agent, changes.

When the type attribute of the element has the value "radio" or "checkbox", this represents the current state of the form control, in an interactive user agent. Changes to this attribute change the state of the form control, but do not change the value of the HTML checked attribute of the INPUT element. Note: During the handling of a click event on an input element with a type attribute that has the value "radio" or "checkbox", some implementations may change the value of this property before the event is being dispatched in the document. If the default action of the event is canceled, the value of the property may be changed back to its original value. This means that the value of this property during the handling of click events is implementation dependent.

setDefaultChecked
