尝试使用 JS 获取查询字符串参数

Question

I'm playing around with a Squarespace Website and attempting to search for/get Query string Parameters. No matter what I try with code injection I get null, of course it works fine in the console but not when I use code injection, it is probably something very simple I'm missing, any help would be appreciated.

www.mysite.com?x=123

(function(){

var urlParams = new URLSearchParams(window.location.search);
console.log(urlParams.get('x')); 

})();

Answer 1

SquareSpace template iFrames in preview version thus it wouldn't work. Starting up local live server was my answer.
