OnClick change all sibling table rows jQuery

I am try to write a jQuery statement to change the table row that is currently clicked to a different foreground color while making all the sibling table rows the same color. Basically making it look like the clicked row is active. Here's what I have so far, this here works the first time, but on the second time on it never sets all the siblings to the non selected color.

<script type="text/javascript">
    function changeRows(currentRow) {
        $(currentRow).css('color', 'green'); // change clicked row to active color
        $(currentRow).parent().siblings().css('color', 'red'); // change all the rest to non active color
    }
</script>开发者_如何转开发  


<table>
  <tr>
    <td onclick="changeRows(this)">123
    </td>
  </tr>
  <tr>
    <td onclick="changeRows(this)">1234
    </td>
  </tr>
  <tr>
    <td onclick="changeRows(this)">12345
    </td>
  </tr>
  <tr>
    <td onclick="changeRows(this)">123456
    </td>
  </tr>
</table>

It's best to handle this type of stuff through classes rather than popping in ad-hoc css rules.

$("td").click(function(){
  $(this).addClass("on").parent().siblings("tr").find("td").removeClass("on");
});

Or you can base it on the TR itself:

$("tr").click(function(){
  $(this).addClass("on").siblings("tr").removeClass("on");
});

I would prefer doing this by adding/removing CSS classes rather than setting CSS directly. I think your issue though is that you're setting the css on the column element rather than on the rows themselves. You might want to try something like:

<script type="text/javascript"> 
    function changeRows(currentElem) {
        var $currentElem = $(currentElem);
        var $currentRow = $currentElem.closest('tr');
        var $table = $currentElem.closest('table');
        $table.find('tr').removeClass('highlight');
        $currentRow.addClass('highlight');
    } 
</script>

instead of using onclick in your html markup use

If you have an id on each td you could do

$('#td1').click(function() {
   $('td').removeClass('.colored'); 
   $(this).addClass('.colored'); // change clicked row to active color    
});
