addField Element addField(string label, string name, string type, FormFieldOptions fieldOptions)
Element addField(string label, string name, FormFieldOptions fieldOptions)
Element addField(string label, string name, string[string] options, FormFieldOptions fieldOptions): Overrides of the base class implementations that more confirm to *my* conventions when writing form html.
addInput Element addInput(string name, string value, string type): Adds a new INPUT field to the end of the form with the given attributes.
addValueArray void addValueArray(string key, string[] arrayOfValues): This takes an array of strings and adds hidden <input> elements for each one of them. Unlike setValue, it makes no attempt to find and modify existing elements in the form to the new values.
getField Element[] getField(string name): Gets the actual elements with the given name
getLabel Element getLabel(string forId): Grabs the <label> with the given for tag, if there is one.
getPostableData string getPostableData(): Returns the form's contents in application/x-www-form-urlencoded format.
getValue string getValue(string field): Gets the value of the field; what would be given if it submitted right now. (so it handles select boxes and radio buttons too). For checkboxes, if a value isn't given, but it is checked, it returns "checked", since null and "" are indistinguishable
removeField void removeField(string name): Removes the given field from the form. It finds the element and knocks it right out.
setValue void setValue(string field, string value): Overrides of the base class implementations that more confirm to *my* conventions when writing form html.
setValue void setValue(string field, string value, bool makeNew): Set's the form field's value. For input boxes, this sets the value attribute. For textareas, it sets the innerText. For radio boxes and select boxes, it removes the checked/selected attribute from all, and adds it to the one matching the value. For checkboxes, if the value is non-null and not empty, it checks the box. If you set a value that doesn't exist, it throws an exception if makeNew is false. Otherwise, it makes a new input with type=hidden to keep the value.

From Element

opIndex ElementCollection opIndex(string selector): Returns a collection of elements by selector. See: Document.opIndex
opIndex Element opIndex(size_t index): Returns the child node with the particular index.
requireElementById SomeElementType requireElementById(string id, string file, size_t line): Calls getElementById, but throws instead of returning null if the element is not found. You can also ask for a specific subclass of Element to dynamically cast to, which also throws if it cannot be done.
requireSelector SomeElementType requireSelector(string selector, string file, size_t line): ditto but with selectors instead of ids
optionSelector MaybeNullElement!SomeElementType optionSelector(string selector, string file, size_t line): If a matching selector is found, it returns that Element. Otherwise, the returned object returns null for all methods.
classes string[] classes [@property getter]: get all the classes on this element
ClassListHelper struct ClassListHelper: The object classList returns.
classList inout(ClassListHelper) classList [@property getter]
classNames alias classNames = classes: Returns a helper object to work with classes, just like javascript.
addClass Element addClass(string c): Adds a string to the class attribute. The class attribute is used a lot in CSS.

hasClass bool hasClass(string c): Returns whether the given class appears in this element.
addChild Element addChild(string tagName, string childInfo, string childInfo2)
Element addChild(Element e)
Element addChild(string tagName, Element firstChild, string info2)
Element addChild(string tagName, Html innerHtml, string info2): Family of convenience functions to quickly add a tag with some text or other relevant info (for example, it's a src for an <img> element instead of inner text). They forward to Element.make then calls appendChild.
addSibling Element addSibling(string tagName, string childInfo, string childInfo2)
Element addSibling(Element e): Another convenience function. Adds a child directly after the current one, returning the new child.
addChildren void addChildren(T t): Convenience function to append text intermixed with other children. For example: div.addChildren("You can visit my website by ", new Link("mysite.com", "clicking here"), "."); or div.addChildren("Hello, ", user.name, "!"); See also: appendHtml. This might be a bit simpler though because you don't have to think about escaping.
appendChildren void appendChildren(Element[] children): Appends the list of children to this element.
reparent void reparent(Element newParent): Removes this element form its current parent and appends it to the given newParent.
stripOut void stripOut(): Strips this tag out of the document, putting its inner html as children of the parent.
removeFromTree Element removeFromTree(): shorthand for this.parentNode.removeChild(this) with parentNode null check if the element already isn't in a tree, it does nothing.

Element make(string tagName, Html innerHtml, string childInfo2)
Element make(string tagName, Element child, string childInfo2): Convenience function to try to do the right thing for HTML. This is the main way I create elements.
firstChild Element firstChild [@property getter]: Returns the first child of this element. If it has no children, returns null. Remember, text nodes are children too.

previousInSource Element previousInSource(): the next or previous element you would encounter if you were reading it in the source. May be a text node or other special non-tag object if you enabled them.
previousElementSibling Element previousElementSibling [@property getter]
nextElementSibling Element nextElementSibling [@property getter]: Returns the next or previous sibling that is not a text node. Please note: the behavior with comments is subject to change. Currently, it will return a comment or other nodes if it is in the tree (if you enabled it with Document.enableAddingSpecialTagsToDom or Document.parseSawComment) and not if you didn't, but the implementation will probably change at some point to skip them regardless.
previousSibling string previousSibling [@property setter]
nextSibling string nextSibling [@property setter]: Returns the next or previous sibling matching the tagName filter. The default filter of null will return the first sibling it sees, even if it is a comment or text node, or anything else. A filter of "*" will match any tag with a name. Otherwise, the string must match the tagName of the sibling you want to find.
getParent T getParent(string tagName): Gets the nearest node, going up the chain, with the given tagName May return null or throw. The type T will specify a subclass like Form, Table, or Link, which it will cast for you when found.

innerText string innerText [@property getter]
textContent alias textContent = innerText: Fetch the inside text, with all tags stripped out.
visibleText string visibleText(): Gets the element's visible text, similar to how it would look assuming the document was HTML being displayed by a browser. This means it will attempt whitespace normalization (unless it is a <pre> tag), add \n characters for <br> tags, and I reserve the right to make it process additional css and tags in the future.

nodeType int nodeType [@property getter]: .
toString string toString(): Turns the whole element, including tag, attributes, and children, into a string which could be pasted into an XML file.
isEmpty bool isEmpty(): Returns if the node would be printed to string as <tag /> or <tag></tag>. In other words, if it has no non-empty text nodes and no element nodes. Please note that whitespace text nodes are NOT considered empty; Html("<tag> </tag>").isEmpty == false.
toPrettyString string toPrettyString(bool insertComments, int indentationLevel, string indentWith): Writes out with formatting. Be warned: formatting changes the contents. Use ONLY for eyeball debugging.
writeToAppender string writeToAppender(Appender!string where): This is the actual implementation used by toString. You can pass it a preallocated buffer to save some time. Note: the ordering of attributes in the string is undefined. Returns the string it creates.
