示例1: executeDeleteAttribute
function executeDeleteAttribute(editor: EditorAPI,
data: TransformationData): void {
const node = data.node;
if (node == null || !isAttr(node)) {
throw new Error("node must be an attribute");
}
const element = node.ownerElement!;
const caretManager = editor.caretManager;
const guiOwnerLoc = caretManager.mustFromDataLocation(element, 0);
// If the node we start with is an Element, then the node in guiOwnerLoc
// is necessarily an Element too.
const guiOwner = guiOwnerLoc.node as Element;
if (!guiOwner.classList.contains("_readonly")) {
const encoded = node.name;
const startLabel = childByClass(guiOwner, "__start_label")!;
// An earlier version of this code relied on the order of attributes in the
// data tree. However, this order is not consistent from platform to
// platform. Using the order of attributes in the GUI is
// consistent. Therefore we go to the GUI to find the next attribute.
const values = startLabel.getElementsByClassName("_attribute_value");
// We have to get the parent node because fromDataLocation brings us to the
// text node that contains the value.
const guiNode = caretManager.mustFromDataLocation(node, 0).node.parentNode;
const index = indexOf(values, guiNode!);
const nextGUIValue = values[index + 1];
const nextAttr = nextGUIValue != null ?
editor.toDataNode(nextGUIValue) : null;
editor.dataUpdater.setAttribute(element, encoded, null);
// We set the caret inside the next attribute, or if it does not exist,
// inside the label.
if (nextAttr !== null) {
editor.caretManager.setCaret(nextAttr, 0);
}
else {
editor.caretManager.setCaret(
guiOwner.getElementsByClassName("_element_name")[0], 0);
}
}
}示例2: replaceSemanticFields
export function replaceSemanticFields(editor: EditorAPI,
data: SemanticFieldTransformationData):
void {
const dataCaret = editor.caretManager.getDataCaret(true)!;
const guiCaret = editor.caretManager.fromDataLocation(dataCaret)!;
const guiSfsContainer = domutil.closestByClass(guiCaret.node,
"btw:semantic-fields",
editor.guiRoot);
if (guiSfsContainer === null) {
throw new Error("unable to acquire btw:semantic-fields");
}
const sfsContainer = editor.toDataNode(guiSfsContainer)!;
const sfsParent = sfsContainer.parentNode!;
const sfsIndex = _indexOf.call(sfsParent.childNodes, sfsContainer);
// Remove the container from the tree.
editor.dataUpdater.removeNode(sfsContainer);
// and manipulate it off-line.
while (sfsContainer.firstChild !== null) {
sfsContainer.removeChild(sfsContainer.firstChild);
}
const doc = sfsContainer.ownerDocument;
const newPaths = data.newPaths;
const mode = editor.modeTree.getMode(sfsContainer);
const ename = mode.getAbsoluteResolver().resolveName("btw:sf")!;
for (const path of newPaths) {
const sf = makeElement(doc, ename.ns, "btw:sf");
sf.textContent = path;
sfsContainer.appendChild(sf);
}
// Finally, reintroduce it to the data tree.
editor.dataUpdater.insertNodeAt(sfsParent, sfsIndex, sfsContainer);
editor.caretManager.setCaret(sfsContainer, 0);
}
