如何根据表中某一列的值隐藏表行 [英] How to hide a table row depending on a value in one of its column

问题描述

我有一个如下表.

<table id="subtask_table" style="width: 80%">
    <tr>
        <th>ID</th>
        <th>Titel</th>
        <th>Beschreibung</th>
        <th>Gemeldet von</th>
        <th>Erstellt am</th>
        <th>Geändert am</th>
        <th>Erledigt</th>


    </tr>

    <tr>
        <td>11</td>
        <td><a href="/taskExplorer/subtasks/edit/11">Termine verschieben</a></td>
        <td></td>
        <td></td>
        <td>2012-07-26 14:34:36</td>
        <td>2012-07-30 08:37:40</td>
        <td>1</td>
        <td><a href="/taskExplorer/subtasks/delete/11">löschen</a></td>
      </tr>
</table>

如果erledigt列(已完成)为0或为空，我想隐藏此表的一行.

What I want to do is hide a row of this table, if the column erledigt (completed) is 0 or empty.

这就是我到目前为止所得到的:

That's what I got this far:

$(document).ready(function() {
    $('#cbHideCompleted').click(function() {
        if($(this).prop('checked')) {

            $('#subtask_table td').each(function() {
                //if td is 'completed' column
                    //if value is 0 or null
                        //hide

            });
        } else {
            $('#subtask_table td').each(function() {
                $(this).show();
            });
        }
    });
});

有没有一种方法可以使用jquery选择器直接访问元素.如果没有，如何实现"//如果td已完成"列?

Is there a way to access the elements directly with a jquery selector. If not, how do I implement "//if td is 'completed' column"?

感谢您的帮助.

推荐答案

假设您的erledigt列始终是倒数第二个列，那么它应该非常简单.

Assuming your erledigt column is always the second last column then it should be very straight forward.

遍历行而不是单元格，并找到每一行的倒数第二个单元格，并根据需要显示/隐藏行.

Iterate through the rows and not the cells and find the second last cell in each row and show/hide the row as required.

$('#subtask_table tr').each(function() {
    var $erledigtCell = $(this).find("td").last().prev();
    var $row = $erledigtCell.parent();

    if($erledigtCell.text() == '1'){
        $row.hide();
    } else {
        $row.show();
    }
});

如果对网格的生成方式有任何影响，则可以向tr中添加自定义属性(例如data-erledigt=...)会更好.比您无需遍历，显示在erledigt的哪一列都没有关系.

If you have any influence on how the grid is generated it would be much better if you can add a custom attribute to the tr, for example data-erledigt=.... Than you have no traversing to do and it doesn't matter which column erledigt is displayed in.

使用这样的HTML:

<tr data-erledigt=0>....
.....
<tr data-erledigt=1>

您可以编写一个简单的jQuery:

You could write a jQuery as simple as:

$("tr[data-erledigt='0']").hide();
