示例1: insertRow
HTMLTableRowElement* HTMLTableElement::insertRow(
int index,
ExceptionState& exceptionState) {
if (index < -1) {
exceptionState.throwDOMException(
IndexSizeError,
"The index provided (" + String::number(index) + ") is less than -1.");
return nullptr;
}
HTMLTableRowElement* lastRow = nullptr;
HTMLTableRowElement* row = nullptr;
if (index == -1) {
lastRow = HTMLTableRowsCollection::lastRow(*this);
} else {
for (int i = 0; i <= index; ++i) {
row = HTMLTableRowsCollection::rowAfter(*this, lastRow);
if (!row) {
if (i != index) {
exceptionState.throwDOMException(
IndexSizeError,
"The index provided (" + String::number(index) +
") is greater than the number of rows in the table (" +
String::number(i) + ").");
return nullptr;
}
break;
}

}
}
ContainerNode* parent;
if (lastRow) {
parent = row ? row->parentNode() : lastRow->parentNode();
} else {

if (!parent) {
HTMLTableSectionElement* newBody =
HTMLTableSectionElement::create(tbodyTag, document());

appendChild(newBody, exceptionState);
return newRow;
}
}
HTMLTableRowElement* newRow = HTMLTableRowElement::create(document());
parent->insertBefore(newRow, row, exceptionState);
return newRow;
}示例2: findRows
static inline RefPtr<HTMLCollection> findRows(const HTMLTableRowElement& row)
{
auto* parent = row.parentNode();
if (is<HTMLTableSectionElement>(parent))
return downcast<HTMLTableSectionElement>(*parent).rows();
if (is<HTMLTableElement>(parent))
return downcast<HTMLTableElement>(*parent).rows();
return nullptr;
}示例3: toHTMLElement
static inline bool isInSection(HTMLTableRowElement& row, const HTMLQualifiedName& sectionTag)
{
// Because we know that the parent is a table or a section, it's safe to cast it to an HTMLElement
// giving us access to the faster hasTagName overload from that class.
return toHTMLElement(row.parentNode())->hasTagName(sectionTag);
