HTML表可选择行Javascript包[关闭]

Is there a Javascript package out there that makes table rows selectable/highlightable by clicking on them and using the Shift and Ctrl keys?

我正在寻找与 iTunes 或其他音乐播放器相同的功能，允许通过单击该行来突出显示一首歌曲，或者通过按住 Shift 或 Control 并单击来突出显示多首歌曲。

无需插件即可完成！

This example highlights a row or multiple ones by holding Ctrl, cmd (for MacOS users) or Shift keyboard key and clicking.

我建议避免使用简单的插件。您会发现，对于您需要实现的目标来说，实现这些代码并不多。

HTML:

假设我有下表（您将与行交互）。

<table border="1">
    <tr>
        <th>Id</th>
        <th>Name</th>
        <th>Age</th>
        <th>Salary</th>
    </tr>
    <tr>
        <td>1</td>
        <td>Luis</td>
        <td>28</td>
        <td>$100,000</td>
    </tr>
    <tr>
        <td>2</td>
        <td>Oscar</td>
        <td>29</td>
        <td>$90,000</td>
    </tr>
    <tr>
        <td>3</td>
        <td>Daniel</td>
        <td>18</td>
        <td>$50,000</td>
    </tr>
</table>

CSS:

现在我将创建一些CSS使用default cursor导航时table （仅用于造型，可以将其删除）和另一个highlight the row.

tr { cursor: default; }
.highlight { background: yellow; }

jQuery:

这就是您需要的全部代码，请阅读评论。

$(function() {

    /* Get all rows from your 'table' but not the first one 
     * that includes headers. */
    var rows = $('tr').not(':first');

    /* Create 'click' event handler for rows */
    rows.on('click', function(e) {

        /* Get current row */
        var row = $(this);

        /* Check if 'Ctrl', 'cmd' or 'Shift' keyboard key was pressed
         * 'Ctrl' => is represented by 'e.ctrlKey' or 'e.metaKey'
         * 'Shift' => is represented by 'e.shiftKey' */
        if ((e.ctrlKey || e.metaKey) || e.shiftKey) {
            /* If pressed highlight the other row that was clicked */
            row.addClass('highlight');
        } else {
            /* Otherwise just highlight one row and clean others */
            rows.removeClass('highlight');
            row.addClass('highlight');
        }

    });

    /* This 'event' is used just to avoid that the table text 
     * gets selected (just for styling). 
     * For example, when pressing 'Shift' keyboard key and clicking 
     * (without this 'event') the text of the 'table' will be selected.
     * You can remove it if you want, I just tested this in 
     * Chrome v30.0.1599.69 */
    $(document).bind('selectstart dragstart', function(e) { 
        e.preventDefault(); return false; 
    });

});

其他功能仅取决于您，我只是回答了您在问题中所需的内容:-)希望这会有所帮助。
