How to select html nodes by ID with jquery when the id contains a dot?
我有一个网站，包含类似的元素:
<p id="root.SomeCoolThing">Some Cool Thing</p>
我不能 Select jQuery为$('#root.SomeCoolThing')的段落，因为jQuery认为SomeCoolThing是id="root"元素的类.
如何使用jQuery Select 此元素？我想避免这样的建设:
$(document.getElementById('root.SomeCoolThing'))
Use the escaping rules from the jQuery selectors API as follows:
$('#root\\.SomeCoolThing')
From the docs:
To use any of the meta-characters (such as
!"#$%&'()*+,./:;<=>?@[\]^`{|}~) as a literal part of a name, it must be escaped with with two backslashes:\\. For example, an element withid="foo.bar", can use the selector$("#foo\\.bar").
