Remove square brackets and their contents using jQuery + regexes

Using an example I’ve found here, I am trying to remove occurrences of text that are surrounded by these [ ] square brackets.

I have many occurrences of [sample-text] in my html and want to remove the whole thing, including the brackets.

I’ve tried this but it doesn’t work — nothing is being replaced:

var replaced = $("body").html().replace(/^[.*]$/g,'');
$("body").html(replaced);

I am trying to match the start using [ and the end with ] and remove the inner content but I am getting nowhere.
