根据选项值更改td背景色

Question

I want to change the td background color based on the color value selected in dropdown.

HTML :

<table border="1">
<tr>
<th>Channel</th>
<th>Health</th>
</tr>
<tr>
<td>Mobile</td>
<td class="tdcolor">
  <select >
    <option value="0">Select</option>
    <option value="1">Green</option>
    <option value="2">Red</option>
    <option value="3">Amber</option>
  </select>
</td>
</tr>
</table>

jquery :

$(document).ready(function(){
  $('td.tdcolor').change( function() {
     $(this).css('background-color','green');
 });
});

The above jquery is not highlighting the background color of td element holding tdcolor class.

If someone could help me how to change this using jquery, it would be great.

Many Thanks in advance.

Answer 1

You should use pseudo-class selector in order to get the selected text from your dropdown.

var text = $(this).find(':selected').text();

 $(document).ready(function(){ $('td.tdcolor').change( function() { $(this).css('background-color',$(this).find(':selected').text()); }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <table border="1"> <tr> <th>Channel</th> <th>Health</th> </tr> <tr> <td>Mobile</td> <td class="tdcolor"> <select > <option value="0">Select</option> <option value="1">Green</option> <option value="2">Red</option> <option value="3">Blue</option> </select> </td> </tr> </table>

 $(document).ready(function() { $('#color').change(function() {//add an id to html and use as selector $(this).parent("td").css('background-color', $('option:selected', this).text());//use the text of selected option as parameter }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <table border="1"> <tr> <th>Channel</th> <th>Health</th> </tr> <tr> <td>Mobile</td> <td class="tdcolor"> <select id='color'> <option value="0">Select</option> <option value="1">Green</option> <option value="2">Red</option> <option value="3">Amber</option> </select> </td> </tr> </table> 

Answer 3

$(document).ready(function(){
  $('select').change( function() {
     $(".tdcolor").css('background-color','green');
 });
});

Should be .tdcolor not ddcolor

The event should be on select
