Constructor Detail

### Element

    protected Element()

Method Detail

### as

    public static Element as(JavaScriptObject o)

  Assert that the given `Node` is an `Element` and automatically typecast it.

### as

    public static Element as(Node node)

  Assert that the given `Node` is an `Element` and automatically typecast it.

### is

    public static boolean is(JavaScriptObject o)

  Determines whether the given `JavaScriptObject` can be cast to an `Element`. 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 an `Element`. A `null` node will cause this method to return `false`.

### dispatchEvent

    public final void dispatchEvent(NativeEvent evt)

  Dispatched the given event with this element as its target. The event will go through all phases of the browser's normal event dispatch mechanism. Note: Because the browser's normal dispatch mechanism is used, exceptions thrown from within handlers triggered by this method cannot be caught by wrapping this method in a try/catch block. Such exceptions will be caught by the `uncaught exception handler` as usual.

  Parameters:
    `evt` - the event to be dispatched

### getAbsoluteLeft

### getAttribute

    public final java.lang.String getAttribute(java.lang.String name)

  Retrieves an attribute value by name. Attribute support can be inconsistent across various browsers. Consider using the accessors in `Element` and its specific subclasses to retrieve attributes and properties.

  Parameters:
    `name` - The name of the attribute to retrieve
  Returns:
    The Attr value as a string, or the empty string if that attribute does not have a specified or default value

### getClassName
