Jquery: Change table row when select option is changed??

when the select option is 1 i want the table row to be blue,

if its 2 then red and if its 3 then yellow. This is my code so far.

<style> table td,th{ border:1px solid black; padding-left:100px; } table tr{ background-color:grey; } } .on{ background-color:blue; } </style>

<body> <table id="table"> <tr> <th> Hello </th>

    <th>
    Is it
    </th>
</tr>   

<tr id="options">
    <td>
    yayaya
    </td>
    <td>
    <select id="select">
        <option value="1">1</option>
        <option value="2">2</option>
        <option value="3">3</option>
    </select>
    </td>
</tr>

</table>

</body>

<script> $('select').change(function(){ if($('select').text() == "1"){ $('#options').addClass('on');
} }):

<script>

This isnt working, any ideas?

$('select').change(function(){ if($('select').val() == "1"){ $('#options').addClass('on'); } });

You also have an extra } in your css
