HTMLTableRowElement - Web API 接口参考 编辑

The HTMLTableRowElement interface provides special properties and methods (beyond the HTMLElement interface it also has available to it by inheritance) for manipulating the layout and presentation of rows in an HTML table.

Properties

Inherits properties from its parent, HTMLElement.

HTMLTableRowElement.align

Is a DOMString containing an enumerated value reflecting the align attribute. It indicates the alignment of the element's contents with respect to the surrounding context. The possible values are "left", "right", and "center".

HTMLTableRowElement.bgColor

Is a DOMString containing the background color of the cells. It reflects the obsolete bgcolor attribute.

HTMLTableRowElement.cells 只读

Returns a live HTMLCollection containing the cells in the row. The HTMLCollection is live and is automatically updated when cells are added or removed.

HTMLTableRowElement.ch

Is a DOMString containing one single character. This character is the one to align all the cell of a column on. It reflects the char and default to the decimal points associated with the language, e.g. '.' for English, or ',' for French. This property was optional and was not very well supported.

HTMLTableRowElement.chOff

Is a DOMString containing a integer indicating how many characters must be left at the right (for left-to-right scripts; or at the left for right-to-left scripts) of the character defined by HTMLTableRowElement.ch. This property was optional and was not very well supported.

HTMLTableRowElement.rowIndex 只读

Returns a long value which gives the logical position of the row within the entire table. If the row is not part of a table, returns -1.

HTMLTableRowElement.sectionRowIndex 只读

Returns a long value which gives the logical position of the row within the table section it belongs to. If the row is not part of a section, returns -1.

HTMLTableRowElement.vAlign

Is a DOMString representing an enumerated value indicating how the content of the cell must be vertically aligned. It reflects the valign attribute and can have one of the following values: "top", "middle", "bottom", or "baseline".

Methods

Inherits methods from its parent, HTMLElement.

HTMLTableRowElement.deleteCell()

Removes the cell at the given position in the row. If the given position is greater (or equal as it starts at zero) than the amount of cells in the row, or is smaller than 0, it raises a DOMException with the IndexSizeError value.

HTMLTableRowElement.insertCell()

Inserts a new cell just before the given position in the row. If the given position is not given or is -1, it appends the cell to the row. If the given position is greater (or equal as it starts at zero) than the amount of cells in the row, or is smaller than -1, it raises a DOMException with the IndexSizeError value. Returns a reference to a HTMLTableCellElement [en-US].
