jQuery selector for all checkboxes of a certain class or id
提问by DrewT
I have an advanced search form on a page and there is also a "clear" button which resets the form. As the form gets cleared I am using this code to un-check the form's checkbox inputs:
我在页面上有一个高级搜索表单，还有一个“清除”按钮可以重置表单。当表单被清除时，我使用此代码取消选中表单的复选框输入：
$('form#advanced_search :input[type=checkbox]').each(function() { this.checked = false; });
Problem is, this code resets all checkboxes on the page (tested in Chrome and FireFox) instead of just the ones in form#advanced_search.
问题是，此代码会重置页面上的所有复选框（在 Chrome 和 FireFox 中测试），而不仅仅是 form#advanced_search 中的复选框。
The same problem also happens using this selector method:
使用此选择器方法也会发生同样的问题：
$('form#advanced_search input:checkbox').each(function() { this.checked = false; });
I read somewhere that jQuery has some buggy issues with checkboxes and radios, but does anyone know a method or work around for this?
我在某处读到 jQuery 在复选框和收音机方面存在一些错误问题，但是有人知道一种方法或解决方法吗？

You're not using the correct selector to get the checkboxes that you want. Try this:
您没有使用正确的选择器来获取所需的复选框。试试这个：
$("#advanced_search input[type='checkbox']").prop("checked", false);

选择器不正确：尝试使用：

It looks like this is a datatables issue specific to my case. So I'll have to dig a bit deeper to solve the problem.The regular selector methods seem to be working with non-auto generated checkboxes on my page.
看起来这是一个特定于我的案例的数据表问题。所以我必须更深入地挖掘来解决这个问题。常规选择器方法似乎在我的页面上使用非自动生成的复选框。
I'll update here once I track down the bug.
一旦我追踪到错误，我会在这里更新。
Thanks everyone!
感谢大家！
