To make jQuery select element with ID param0.typeParameter instead of element with ID param0 and class name typeParameter you should use the following:

$('#param0\\.typeParameter');

Official Proof

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").

You can try this instead:

$('[id="param0.typeParameter"]');

Or else the code assumes you want to select an element with id param0 and class typeParameter

jQuery uses the CSS-selector language. Which causes "#param0.typeParameter" to be interpretted as an element with id param0 and class typeParameter.

The jQuery statement is more similar to:

document.querySelector("#param0.typeParameter");
