定义表结构
1. 通过id遍历
<html>
<body>
<table id="tb" border="1">
<tr>
<td>row1,cell1</td> <td>row1,cell2</td>
</tr>
<tr>
<td>row2,cell1</td> <td>row2,cell2</td>
</tr>
<tr>
<td>row3,cell1</td> <td>row3,cell2</td>
</tr>
</table>
<button type="button" onclick="f()">click me</button>
<script>
function f()
{
var t=document.getElementById("tb");
if (t)
{
for(var i=0; i< t.rows.length; i++)
{
for(var j=0; j<t.rows[i].cells.length; j++)
{
alert(t.rows[i].cells[j].innerText);
}
}
}
}
</script>
</body>
</html>
2. 通过jQuery遍历
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<table class="tb" border="1">
<tr>
<td>row1,cell1</td>
<td>row1,cell2</td>
</tr>
<tr>
<td>row2,cell1</td>
<td>row2,cell2</td>
</tr>
</table>
<script type="text/javascript" src="./js/jquery-1.11.1.min.js"></script>
<script>
$(document).ready(function(){
$("td").each(function(){
alert($(this).text());
})
})
</script>
</body>
</html>
添加按钮，按按钮时弹出
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<table class="tb" border="1">
<tr>
<td>row1,cell1</td>
<td>row1,cell2</td>
</tr>
<tr>
<td>row2,cell1</td>
<td>row2,cell2</td>
</tr>
</table>
<button type="button">click me</button>
<script type="text/javascript" src="./js/jquery-1.11.1.min.js"></script>
<script>
$(document).ready(function(){
$("button").click(function(){
$("td").each(function(){
alert($(this).text());
})
})
})
</script>
</body>
</html>
