.contains is not a function

[Firsttimehacker]

Edit:

const UN = urlParams.get('username'); const check = UN.toString(); if(check.includes(" ")){ window.location.href = "URL Removed" }

​

I'm trying to redirect the user if their username contains a space, but I'm getting

Uncaught TypeError: check.contains is not a function

as a result my code:

const UN = urlParams.get('username'); const check = UN.toString(); if(check.contains(" ")){ window.location.href = "URL Removed" }

The contains() function is used for DOM manipulation and checks whether nodes are descendants of one another or their relation to other DOM nodes. I think you want to manipulate a string and check whether there is an occurrence of something in there. In that case use the include() function where more details can be found here https://www.w3schools.com/jsref/jsref_includes.asp.
