我想请一些帮助。
<h2>Operating systems <span class="button small toggle-btn">Toggle</span></h2>
<table class="data" cellpadding="8" border="1">
<thead>
<tr>
<th class="first" style="width:120px">
Operating System </th>
<th class="">
Percentage </th>
</tr>
</thead>
<tbody>
<tr>
<td class="">iOS 8.4</td>
<td class="">
<div class="ui-percentage" style="width:17%">17 %</div>
</td>
</tr>
<tr class="tr even">
<td class="">iOS 8.3</td>
<td class="">
<div class="ui-percentage" style="width:6%">6 %</div>
</td>
</tr>
<tr>
<td class="">iOS 8.2</td>
<td class="">
<div class="ui-percentage" style="width:11%">11 %</div>
</td>
</tr>
<tr class="tr even">
<td class="">iOS 8.1.3</td>
<td class="">
<div class="ui-percentage" style="width:11%">11 %</div>
</td>
</tr>
<tr>
<td class="">iOS 8.1</td>
<td class="">
<div class="ui-percentage" style="width:6%">6 %</div>
</td>
</tr>
</tbody>
</table>
第一次加载页面时,我想要折叠表格。当我单击切换按钮时,我想更改表状态,所以基本上要扩展它并再次折叠它再次点击按钮。
这是我的剧本
<script>
$(document).ready(function() {
$('.toggle-btn').closest('table').hide(); // I want to target the table right after the button
$('.toggle-btn').on('click', function(event) {
$(this).closest('table').toggle();
});
});
</script>
如何才能使这项工作正确?

为什么不直接使用切换功能?
$(document).ready(function() {
$('table').hide();
$('.toggle-btn').on('click', function() {
$('table').toggle();
});
});

如果您只有一个 table
,那么只执行
$(document).ready(function() {
$('tbody').closest('h2').next().find("tbody").hide();
$('.toggle-btn').on('click', function() {
$('tbody').toggle();
});
});
对于多个兄弟表
您可以找到距离最近的h2
,next()
可以找到table
$(document).ready(function() {
$('.toggle-btn').closest('h2').next().find("tbody").hide();
$('.toggle-btn').on('click', function() {
$(this).closest('h2').next().find("tbody").toggle();
});
});

$(document).ready(function() {
$('.toggle-btn').parent().next('table').hide(); // I want to target the table right after the button
$('.toggle-btn').on('click', function(event) {
$(this).parent().siblings('table').toggle();
});
});
选择器应为$('.toggle-btn').parent().next('table')

函数ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
上升到元素的父元素,因此它永远不会找到表格。你必须做这样的事情:
closest()
但如果有多个表,这将无效。考虑使用id或表,以便您可以直接访问它。例如:
$(document).ready(function() {
$('.toggle-btn').parent().parent().find('table').hide(); // I want to target the table right after the button
$('.toggle-btn').on('click', function(event) {
$(this).parent().parent().find('table').toggle();
});
});
这会使javascript变得更简单,即:
<table id="data-table-1" class="data" cellpadding="8" border="1">
