jQuery实现表格隔行换色
本文实例为大家分享了jQuery实现表格隔行换色的具体代码,供大家参考,具体内容如下
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>使用JQ完成表格隔行换色</title>
<script src="js/jquery.min.js"></script>
<script>
$(function() {
$("tbody tr:odd").css("background-color","aquamarine");
$("tbody tr:even").css("background-color","bisque");
var tb = $("tbody tr");
var oldColor;
for(var i=0;i<tb.length;i++) {
//alert(oldColor);
$("tbody tr")[i].onmouseover = function() {
oldColor = this.style.backgroundColor;
this.style.backgroundColor = "yellow";
}
$("tbody tr")[i].onmouseout = function() {
this.style.backgroundColor = oldColor;
}
}
});
</script>
</head>
<body>
<table id="tbl" border="1" border-collapse="collapse" align="center" cellspacing="0" cellpadding="5" width="400" height="20">
<thead>
<tr>
<th>编号</th><th>姓名</th><th>年龄</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td><td>张三</td><td>12</td>
</tr>
<tr>
<td>2</td><td>李四</td><td>22</td>
</tr>
<tr>
<td>3</td><td>王五</td><td>13</td>
</tr>
<tr>
<td>4</td><td>马六</td><td>14</td>
</tr>
<tr>
<td>5</td><td>伍六七</td><td>17</td>
</tr>
<tr>
<td>6</td><td>梅花十三</td><td>17</td>
</tr>
</tbody>
</table>
</body>
</html>
疑问:为什么this.style.backgroundColor = oldColor中的this不能用$("tbody tr")[i]代替??
