我写了HTML表,其中每一行都有一个复选框。所以现在我想在标题中添加复选框,该复选框将检查表中的所有复选框。我已经做到了,但是没有用。有想法吗?
<table class="table table-hover table-inbox">
<thead>
<tr>
<th>
<input type="checkbox" class="i-checks" id="allmsgs">
</th>
<th>Sender</th>
<th>Message</th>
<th>Last Message</th>
</tr>
</thead>
<tbody>
<tr class="">
<td class="">
<input type="checkbox" name="1" class="i-checks msg">
</td>
<td><a href="#">Jeremy Massey</a></td>
<td><a href="#">Lorem ipsum dolor sit amet, consectetur adipiscing elit.</a></td>
<td class="mail-date"><a href="#">12/12/2019 15:35</a></td>
</tr>
<tr class="unread active">
<td class="">
<input type="checkbox" name="2" class="i-checks msg">
</td>
<td><a href="#">Marshall Horne</a></td>
<td><a href="#">Praesent nec nisl sed neque ornare maximus at ac enim.</a></td>
<td class="mail-date">12/12/2019 15:35</td>
</tr>
<tr>
<td class="">
<input type="checkbox" name="3" class="i-checks msg">
</td>
<td><a href="#">Grant Franco</a></td>
<td><a href="#">Etiam maximus tellus a turpis tempor mollis.</a></td>
<td class="mail-date">12/12/2019 15:35</td>
</tr>
</tbody>
</table>
我还具有javascript功能...
$(document).ready(function() {
$('#allmsgs').click(function(event) {
if(this.checked) {
$('.msg').each(function() {
this.checked = true;
});
} else {
$('.msg').each(function() {
this.checked = false;
});
}
});
});
位于我的scripts.js
文件中,并且该文件与html链接(链接不是问题,因为其他功能正在工作。

如果您添加jquery
库,则该方法有效:)
$(document).ready(function() {
$('#allmsgs').click(function(event) {
if(this.checked) {
$('.msg').each(function() {
this.checked = true;
});
} else {
$('.msg').each(function() {
this.checked = false;
});
}
});
});

在您链接的网站上,单击元素是
<ins class="iCheck-helper" style="position: absolute; top: 0%; left: 0%; display: block; width: 100%; height: 100%; margin: 0px; padding: 0px; background: rgb(255, 255, 255); border: 0px; opacity: 0;"></ins>
请尝试将id allmsgs
设置为ID而不是输入(如果它在html中公开)。
