是否有一个
Javascript包,通过单击它们并使用Shift和Ctrl键使表行可选/可突出显示？
我正在寻找与iTunes或其他音乐播放器相同的功能,它允许通过单击行突出显示一首歌曲或通过按住shift或控制并单击来突出显示多个.

没有插件就可以做到！
此示例通过按住Ctrl,cmd(对于MacOS用户)或Shift键盘键并单击来突出显示一行或多行.
我建议避免使用插件来处理简单的事情.您将看到,实现您需要实现的代码并不是很多代码.

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以在导航表时使用默认光标(仅用于样式,可以删除它),另一个用于突出显示行.
tr { cursor: default; }
.highlight { background: yellow; }
jQuery的：
$(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;
});
});
最后,如果您坚持创建插件,可以查看此站点并根据需要自定义代码.
