Using jquery to get value of text area in closest table cell
Question
I have the following table
<tr>
<td data-toggle="tooltip" title="Not Started"><img src="images/small_info_icon.png"></td>
<td>Demo Demo</td>
<td>January</td>
<td class="updaterow"><textarea class="form-control" rows="5" id="notes34455" name="editcomments">Not Started</textarea></td>
<td id="34455"><button type="button" id="updatestatus" class="btn btn-info btn-sm">Update</button> </td>
</tr>
I want to use jquery to get the value of the textarea. I am using the following, but it is giving undefined.
$("button#updatestatus").click(function(){
var id = $(this).closest('td').attr('id');
var data = $(this).closest("updaterow").text;
alert(data);
var data = {
id: id,
};
$.ajax({
type: "POST",
url: "updatestatus.php",
data: data
}).done(function(msg) {
console.log(msg);
});
Is it possible to get the textvalue of the textarea?

.closest() looks for the closest containing element that matches the selector. .updaterow doesn't contain button#updatestatus , so it won't find it. .updaterow is the previous td , so it should be:
var data = $(this).closest("tr").siblings(".updaterow").text();
You also forgot the . in .updaterow and the () in .text() .

This is what you want
$("button#updatestatus").click(function(){
var data = $(this).parent().prev("td.updaterow").find("textarea").val();
alert(data);
});
Here is an example
$("button#updatestatus").click(function(){ var data = $(this).parent().prev("td.updaterow").find("textarea").val(); alert(data); });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <html> <table> <tr> <td data-toggle="tooltip" title="Not Started"><img src="images/small_info_icon.png"></td> <td>Demo Demo</td> <td>January</td> <td class="updaterow"><textarea class="form-control" rows="5" id="notes34455" name="editcomments">Not Started</textarea></td> <td id="34455"><button type="button" id="updatestatus" class="btn btn-info btn-sm">Update</button> </td> </tr> </table> </html>

This is what you need -
$(this).closest('tr').find('textarea').val();
Here is a fiddle for the same - https://jsfiddle.net/v44rzxLo/1/ . On a side note, do not have same ids for multiple elements.
