  <tr class="numbers" id="1">
   <td class="a" align="right">1</td>
   <td class="a" align="left">Tue</td>
   <td class="b"><input class="input" type="text" title="" value=""/></td>
   <td class="c"><input class="input" type="text" title="" value=""/></td>

   <td class="g"><input class="input" type="text" title="" value=""/></td>
 </tr>

any suggestion on what i might be doing wrong any aid is greatly appreciated

Answer 1

Try putting value in quotes.

Answer 2

Two problems here, first your IDs should not start with a number, use a prefix, like row1, then use .val() to get the value, like this:

var kom =$("tr#row1 .b input").val();

If you were to use .attr(), you would use it like this .attr('value'), currently it's looking for .attr(undefined). I put if in italics because you should pretty much always use .val() to get or set a value on an <input>...same goes for <select> and <textarea>.

Answer 3

Accessing the DOM's value attribute can be a bit funky. Try this:

var kom =$("tr#1 .b input").val();

Answer 4

$("tr#1 .b input").attr("value");

watch that you havent enclosed value in "value"

Answer 5

This is what you want:

var kom = $(".b input").val();

Answer 6

var kom =$("tr#1 .b input").attr("value")

or better

var kom =$("tr#1 .b input").val();
