使用jQuery根據單元格值更改行的顏色

Question

我想知道如何根據單元格的值設置行顏色。爲此我使用JQuery。

在我的情況下，我想爲每行progress單元格的文本等於'待定'設置紅色。

我寫這個JQuery：

$(document).ready(function() { 
    var table = $('#my-orders-table'); 
    var rows_pending = $('#my-orders-table > tr > td.progress'); 
    # Can't figure out how to get just those rows which has 'Pending' in `td class="progress"` text 
}); 

。

<table width="70%" id="my-orders-table" class="table table-striped table-bordered table-hover">   
    <thead> 
     <tr>        
      <th class="orderable translator"><a href="?sort=translator">Translator</a></th>           
      <th class="orderable short_description"><a href="?sort=short_description">short description</a></th>            
      <th class="language_from orderable"><a href="?sort=language_from">language from</a></th>            
      <th class="language_to orderable"><a href="?sort=language_to">language to</a></th>            
      <th class="level orderable"><a href="?sort=level">level</a></th>            
      <th class="created orderable"><a href="?sort=created">created</a></th>            
      <th class="modified orderable"><a href="?sort=modified">modified</a></th>            
      <th class="orderable price"><a href="?sort=price">Price</a></th> 
      <th class="orderable progress"><a href="?sort=progress">Progress</a></th>            
      <th class="edit_entries orderable"><a href="?sort=edit_entries">Edit Entries</a></th>        
     </tr> 
    </thead>       
    <tbody>       
     <tr class="even">     
       <td class="translator">Not Yet</td>     
       <td class="short_description">Short desc</td>     
       <td class="language_from">Russian</td>     
       <td class="language_to">Magyar</td>     
       <td class="level">Standard level</td>     
       <td class="created">05/29/2016 4:32 p.m.</td>     
       <td class="modified">05/29/2016 4:33 p.m.</td>     
       <td class="price">Not Yet</td>     
       <td class="progress">Pending</td>     
       <td class="edit_entries"><a href="/jobs/update/16">Edit Order</a></td>     
     </tr> 
    </tbody> 
    <tfoot></tfoot> 
</table>

tr不是直接子#my-orders-table。您應該使用#my-orders-table > tbody > tr選擇器而不是#my-orders-table > tr > td.progress和filter()方法如下。

$(document).ready(function() { 
 
    var table = $('#my-orders-table'); 
 
    $('#my-orders-table > tbody > tr').filter(function() { 
 
    return $(this).find('td.progress').text().trim() == 'Pending' 
 
    }).css('background-color', 'red'); 
 
});
