rowIndex property

Retrieves the position of the object in the rows collection for the table.

Syntax

JavaScript	`p = object.rowIndex`

Property values

Type: Integer

Integer that specifies the index number.

Standards information

Document Object Model (DOM) Level 1 Specification, Section 2.5.5

Remarks

This property is different from sectionRowIndex, which indicates the object's position in the tBody, tHead, or tFoot rows collection. These sections are mutually exclusive, so the tr is always contained in one of these sections and in the table. You can determine the rowIndex property of an object by the order in which the object appears in the HTML source.

Examples

This example function shows how to use the rowIndex attribute to format a table. The function sets the background color of the rows in the table to black or white, alternating row by row.

JavaScript


function formatTable(oTable)
{
  var rows=oTable.rows;
  for(var i=0;i<rows.length;i++)
  {
    if(i%2==0) {
      rows[i].style.backgroundColor = "black";
      rows[i].style.color = "white";
    } else {
      rows[i].style.backgroundColor = "white";
      rows[i].style.color = "black";
    }
  }
}
