> How to select html nodes by ID with jquery when the id contains a dot?
I have a website that contains elements similar to this:
<p id="root.SomeCoolThing">Some Cool Thing</p>
I can not select the paragraph with jQuery like $('#root.SomeCoolThing') because jQuery thinks, SomeCoolThing is the class of an element with id="root".
How can I select this element with jQuery? I would like to avoid a construction like this:
$(document.getElementById('root.SomeCoolThing'))
Jquery Solutions
Solution 1 - Jquery
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 with
> id="foo.bar", can use the selector $("#foo\\.bar").
Solution 2 - Jquery
Using attr works:
$('p[id="root.SomeCoolThing"]')
Solution 3 - Jquery
You need to escape special chars:
$('#root\\.SomeCoolThing')
docs: >If you wish to use any of the meta-characters ( such as !"#$%&'()*+,./:;<=>?@[]^`{|}~ ) as a literal part of a name, you must escape the character with two backslashes: \\. For example, if you have an element with id="foo.bar", you can use the selector $("#foo\\.bar").
Solution 4 - Jquery
You can escape period using something like this
$("#root\\.SomeCoolThing")

Solution 5 - Jquery
Shooting from the hip here, but if you cannot change the ID of the element, try using this selector:
$("p[id=root.SomeCoolThing]")
Solution 6 - Jquery
Use two backslashes before each special character
$('#root\\.SomeCoolThing')
