<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
