iIndex

Integer that receives Integerthat specifies the index number.

The property is read-only. The property has no default value.

Remarks

This property is different from sectionrowindex, which indicates the object's position in the tbody, thead, or tfoot?b>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.

DHTML代码范例

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.

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";
}
}
}
