使用JQuery根據單元格值更改行的顏色

Question

我試圖弄清楚如何根據單元格的值設置行顏色。 我為此使用JQuery 。

在我的情況下，我想為每一行設置紅色，以便progress單元格文本等於“ Pending”。

我已經寫了這個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>

        </tr>
    </thead>                        
    <tbody>

tr不是#my-orders-table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，如下所示。

 $(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'); });
