jQuery to get the values of td inside a table

<table id="GridView1">
 <tr>
    <th>KeyWord</th>
    <th>Identifiers</th>
    <th>Values</th>
 </tr>
 <tr>
    <td>
        <select >
           <option selected="selected" value="Action A">Action A</option>
           <option  value="Action b">Action b</option>
           <option value="Action C">Action C</option>
        </select>
    </td>
    <td>
        <textarea >adsasd</textarea>
    </td>
        <td>
        <textarea >dsad</textarea>
    </td>
 </tr>
  <tr>
    <td>
        <select >
           <option value="Action A">Action A</option>
           <option selected="selected" value="Action b">Action b</option>
           <option value="Action C">Action C</option>
        </select>
    </td>
    <td>
        <textarea >asdasd</textarea>
    </td>
        <td>
        <textarea >sdsad</textarea>
    </td>
 </tr>
 </table>

This is the js.

var xml = '<?xml version="1.0" encoding="utf-8"?>';
xml = xml + '<Root>';
i=0;
$("#GridView1 tr").each(function () {

 $(this).find('td').each (function() {
    alert($(this).find('select').val())

  alert($(this).find('textarea').val())


});

});

xml = xml + '</Root>'
alert(xml)

I am getting all the values inside the td but also getting undefined. Any idea why ?

Find all select and textarea in tr instead of td like following.

$("#GridView1 tr").find('select, textarea').each(function () {
    alert(this.value);
});

Demo

$("table").find("td").each(function(){
alert($(this).html());


})

You get undefined because it tries to display the select value AND the textarea value for EACH td.

To show only the existing values, just check if the element exists within the td:

if($(this).find('textarea').length > 0) {
  alert($(this).find('textarea').val());
}
