You can also use $.escapeSelector
$("#"+$.escapeSelector("mainid|label"))
$.escapeSelector automatically manage every single special character present in your string
Since | is a meta character, you have to escape it
$("#mainid\\|label")
To use any of the meta-characters ( such as !"#$%&'()*+,./:;<=>?@[]^`{|}~ ) 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 $("#foo\.bar").
- Use the attribute selector
Description: Selects elements that have the specified attribute, with any value.
console.log($('[id="mainid|label"]').text())<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<span id='mainid|label'>mainid|label</span>Related
