Trying to get value from textbox in column in table


I dynamically created a table with three columns.




<tr>
<td>1</td>
<td>SegName</td>
<td><input type='text' /></td>
</tr>



I'm trying to write a function that goes through each row and grabs the value in that will be in the textbox.



Javascript:




$("#codeSegmentBody").children().eq(x).children().eq(2).val();



The code brings brings up undefined when I do val(), but if I do html it'll grab the html of the textbox.



How can I get this to bring me the value?

  1. <table id="test">
    <tr>
    <td>
    <input type="text" value="123">
    </td>
    </tr>
    <tr>
    <td>
    <input type="text" value="abc">
    </td>
    </tr>
    </table>

    <script type="text/javascript">
    $(document).ready(function(){

    $("#test").find(":input[type=text]").each(function(){

    alert( $(this).val() );

    });

    });
    </script>

  2. Assuming #codeSegmentBody is the name of your table, try this:

    $("#codeSegmentBody td input").each(function() {
    var inputValue = $(this).val();
    alert(inputValue);
    });

  3. $("#codeSegmentBody tr input[type='text']").each(function(){
    alert($(this).val());
    })

  4. Try this

    $("#codeSegmentBody tr").each(function() {
    alert($(this).find("input").val());
    });

  5. You are referencing the containing <td> not the input. Try:

    $("#codeSegmentBody").children().eq(x).find(":text").val();

  6. var str = "";
    $("#codeSegmentBody .third-column input").each(function()
    {
    str += this.value;
    });
    alert(str);

  7. Not easier

    $("table tr td input").val();


    ?

    BTW. You don't have any value in this input anyway.
