Methods

Protected_buildDomNode

  • _buildDomNode(node): Container

  • If the current node contains a root, recursively append its children to this node and return it. Otherwise return the current node. Also add each child to the parent under its keyed name.

    Parameters

    • node: {
          children?: any;
          root?: any;
          [x: string]: any;
      }

      The current element in the dom structure which must be recursively traversed and appended to its parent.

      • [x: string]: any
      • Optionalchildren?: any

        The children of the root node.

      • Optionalroot?: any

        The root node of the dom structure.

    Returns Container

    The recursively appended element node.

append

appendAfter

  • appendAfter(element, referenceElement): void

  • Appends an element to the container just after the specified reference element.

    Parameters

    • element: any

      The element to append.

    • referenceElement: any

      The element after which the element will be appended.

    Returns void

    Fires

    'append'

appendBefore

buildDom

  • buildDom(dom): void

  • Takes an array of pcui elements, each of which can contain their own child elements, and appends them to this container. These child elements are traversed recursively using _buildDomNode.

    Parameters

    • dom: any[]

      An array of child pcui elements to append to this container.

    Returns void

    Example

    buildDom([
        {
            child1: pcui.Label()
        },
        {
            root: {
                container1: pcui.Container()
            },
            children: [
                {
                    child2: pcui.Label()
                },
                {
                    child3: pcui.Label()
                }
            ]
        }
    ]);

unbind

  • unbind(name?, fn?): Events

    Returns Events

    The current instance for chaining.

    Example

    // Register an event listener
    const callback = (arg1, arg2) => {
        console.log('Event triggered with arguments:', arg1, arg2);
    };
    events.on('testEvent', callback);

    // Unbind the specific event listener
    events.unbind('testEvent', callback);

    // Unbind all listeners for a specific event
    events.unbind('testEvent');

    // Unbind all listeners for all events
    events.unbind();
