当有人点击#collapseOne锚时,页面会重新加载并滚动到顶部。我需要禁用它。但是,我无法将href更改为其他任何内容,因为它用于网站的功能。是否可以阻止网站滚动到顶部或阻止网站重新加载?
<div class="accordion" id="accordion2">
<div class="accordion-group">
<div class="accordion-heading">
<a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseOne">
Collapsible Group Item #1
</a>
</div>
<div id="collapseOne" class="accordion-body collapse in">
<div class="accordion-inner">
Anim pariatur cliche...
</div>
</div>
</div>
<div class="accordion-group">
<div class="accordion-heading">
<a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseTwo">
Collapsible Group Item #2
</a>
</div>
</div>
这是JavaScript。这是Twitter Bootstrap。

$('a.accordion-toggle').on('click', function(e) {
// whatever other code this click event needs to run here...
e.preventDefault();
}
e
是事件对象,调用preventDefault
方法会使其停止正常行为(在这种情况下重新加载页面并重置滚动位置)。您可能需要将其与现有的点击处理代码相结合才能使其正常工作(显然您没有提供所有代码)。
return false
也与e.preventDefault()
类似(实际上它只运行e.preventDefault
和e.stopPropagation
,这会阻止点击事件传播到DOM中的父元素。

我会一直推荐你,不要使用preventDefault
(跨浏览器问题)。
return false
也不那么依赖。
我在过去遇到了同样的问题。我使用它,因为它适用于所有浏览器!!!
$('#my_herf_id').on('click', function() {
// code..
$("#my_herf_id").attr('href','javascript:void(0)');
}
