本文實(shí)例講述了jQuery實(shí)現(xiàn)獲取table表格第一列值的方法。分享給大家供大家參考,具體如下:
先來(lái)看看運(yùn)行效果截圖:
完整代碼如下:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" >
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
<title>無(wú)標(biāo)題頁(yè)</title>
<script src="jquery-1.4.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function(){
$("#Button1").click(function(){
var cols="";
$("#tb tr").each(function(){
var text = $(this).children("td:first").text();
cols+=text+"|";
})
cols=cols.length>0?cols.substring(0,cols.length-1):"";
alert(cols);
})
})
</script>
</head>
<body>
<input id="Button1" type="button" value="button" />
<table id="tab1" border="1" style="width:100%;">
<tr>
<th>Id</th>
<th>Name</th>
<th>Address</th>
</tr>
<tbody id="tb">
<tr>
<td>11</td>
<td>leaf</td>
<td>gz</td>
</tr>
<tr>
<td>22</td>
<td>flower</td>
<td>gz</td>
</tr>
</tbody>
</table>
</body>
</html>
希望本文所述對(duì)大家jQuery程序設(shè)計(jì)有所幫助。
