(1)获取行号
<table> <tr onmouseover ="showIndex(this)"><td>1</td></tr> <tr onmouseover ="showIndex(this)"><td>2</td></tr> <tr onmouseover ="showIndex(this)"><td>3</td></tr> <tr onmouseover ="showIndex(this)"><td>4</td></tr> </table>
function showIndex(pVal) { alert(pVal.rowIndex); }
(2)改变颜色、符号
/*在行上改变 图片*/ for(var i=0;i<=pTable.rows.length-1;i++) { var row=pTable.rows[i]; row.onmouseover = function() {/*js this是事件的触发者*/ this.style.backgroundColor="#ffff00"; var tempDv = this.childNodes[0].childNodes[0]; var currentY = parseInt(tempDv.style.backgroundPositionY.split('px')[0]); var newY = currentY - 30 + "px"; tempDv.style.backgroundPositionY = newY; } row.onmouseout = function() { this.style.backgroundColor="#ffffff"; var tempDv = this.childNodes[0].childNodes[0]; var currentY = parseInt(tempDv.style.backgroundPositionY.split('px')[0]); var newY = currentY + 30 + "px"; tempDv.style.backgroundPositionY = newY; } }
（3）excel表格效果
