Class HtmlScript

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, ScriptElement, org.w3c.dom.Element, org.w3c.dom.Node
    public class HtmlScript
extends HtmlElement
implements ScriptElement
    Wrapper for the HTML element "script".
    When a script tag references an external script (with attribute src) it gets executed when the node is added to the DOM tree. When the script code is nested, it gets executed when the text node containing the script is added to the HtmlScript.
    The ScriptFilter feature of NekoHtml can't be used because it doesn't allow immediate access to the DOM (i.e. document.write("<span id='mySpan'/>"); document.getElementById("mySpan").tagName; can't work with a filter).

      • onAllChildrenAddedToPage

        public void onAllChildrenAddedToPage​(boolean postponed)
        Executes the onreadystatechange handler when simulating IE, as well as executing the script itself, if necessary. Lifecycle method invoked after a node and all its children have been added to a page, during parsing of the HTML. Intended to be overridden by nodes which need to perform custom logic after they and all their child nodes have been processed by the HTML parser. This method is not recursive, and the default implementation is empty, so there is no need to call super.onAllChildrenAddedToPage() if you implement this method.
        Overrides:
        onAllChildrenAddedToPage in class DomNode
        Parameters:
        postponed - whether to use PostponedAction or no

        Overrides:
        isEmptyXmlTagExpanded in class DomElement
        Returns:
        true to make generated XML readable as HTML

      • printChildrenAsXml

        protected void printChildrenAsXml​(java.lang.String indent,
                                  java.io.PrintWriter printWriter)
        Recursively writes the XML data for the node tree starting at node.
        Overrides:
        printChildrenAsXml in class DomNode
        Parameters:
        indent - white space to indent child nodes
