There are several ways to check. document.URL is a String, so you can use for example:

 //use indexof
 document.URL.indexOf('this is my input string') > -1;

 //use the String.search method (equivalent to indexOf)
 document.URL.search('this is my input string') > -1

 //use a regular expression with method 'test'
 /this is my input string/i.test(document.URL);

You can use indexOf() Method to return the position of the first occurrence of a specified value in a string.

Or, use search() Method with a regular expression. Which is much more powerful.

Check the info in w3school:
