Jquery 遍历一个table 遇到的一个问题
<table id = "yxfs_table">
<tr>
<td><input type = 'checkbox'/></td>
<td>1</td>
<td><input type="text" value="a" ></td>
</tr>
<tr>
<td><input type = 'checkbox'/></td>
<td>2</td>
<td><input type="text" value="b" ></td>
</tr>
<tr>
<td><input type = 'checkbox'/></td>
<td>3</td>
<td><input type="text" value="c" ></td>
</tr>
<tr>
<td><input type = 'checkbox'/></td>
<td>4</td>
<td><input type="text" value="d" ></td>
</tr>
</table>




var tab = document.getElementById("yxfs_table");
var len = tab.rows.length;
var fs_lab = "";
for (var j=0;j<len;j++){
var fsnm,fsxh;
var tr = $("tr:eq(" + j + ")");
fsnm = tr.find("td:eq(1)").text();

//这里不知道怎么取text里面的value值
//fsxh = tr.find("td:eq(2)").find("input").attr("value");
//fsxh = tr.find("td:eq(2)").find("input").val();
if(j == 1){
fs_lab += fsxh+"、" + fsnm;
}else{
fs_lab += ";" + fsxh+"、" + fsnm;
}
}


本人初学jquery 在遍历table时候 获取input里面 value值 的方法不对，一直取不到值。请各位高手帮忙解决一下谢谢了... jquery 遍历

$('#yxfs_table input[type=text]').each(function() {
alert($(this).val());
