<table id="tbitem"> <tr><td>测试数据1</td></tr> <tr><td>测试数据2</td></tr> <tr><td>测试数据3</td></tr> <tr><td>测试数据4</td></tr> <tr><td>测试数据5</td></tr> <tr><td>测试数据6</td></tr> </table> <script type="text/javascript"> var table = document.getElementById("tbitem"); var td = table.getElementsByTagName("td"); var len = td.length; for(i=0;i<len;i++){ alert(td[i].innerHTML); } </script>
jquery 版的
$(document).ready(function(){
var st1r="";
$("td").each(function(){ st1r+=$(this).html()+",";alert( st1r)})
});
这个是通过判断里面是否有td ，如果有td，都提取里面的值
