Answer 1

You can use closest('tr') to get the row for current button and use index() to get the index of the row.

Live Demo

$(this).closest('tr').index()

Answer 2

May be something like the code below will help you to get the required information.

$("button").click(function () {
    var $row = $(this).parent().parent(); //tr
    var $columns = $row.find('td');
    var rowIndex = $row.index();
    var values = new Array();
    for (var i = 0; i < $columns.length - 1; i++) {
        var item = $columns[i];
        values.push($(item).children().val());
    }
    alert(JSON.stringify(values));
});

You can use parents() function for the same.

var tr = $(this).parents('tr');

this would give your row on which button was clicked.

<tr>
  <td><input type="text" name ="name"/></td>
  <td>
      <select name="select_job">
         <option value="1"> Engineer </option>
         <option value="2"> Doctor </option>
      </select>
  </td>
  <td><button>update </button></td>
</tr>


$("button").click(function () {
    var $row = $(this).parents('tr:first');

    var txt = $row.find('input[type=text]').val();
    var salVal = $row.find('select:selected').val();

    alert(txt+' '+salVal);
});

Answer 4

You can use like this

$("button").click(function () {
    var inputValue = $(this).closest("tr").find("input[type=text]").val();
    var selectValuse = $(this).closest("tr").find("[name='select_job']").val();
    var index = $(this).closest("tr").index();
});
