Set up a table. When the mouse moves to a certain row, the color changes. When the mouse leaves, the color changes to the original color. Each line requires two mouse events:
1. Mouse override: onMouseOver
2. Mouse out: onMouseOut
At the same time, these two events need to call the event function:
1. To set the color of the row:
resetColor(row)
2. Implement the change of row color:
changeColor(row)
Implementation code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN">
<html>
<head>
<title>变色表格示例</title>
<script type="text/javascript">
function changeColor(row){
document.getElementById(row).style.backgroundColor='#9999FF';
}
function resetColor(row){
document.getElementById(row).style.backgroundColor='';
}
</script>
