change wp results page depending on its url

Question

I hope you can help me to figure this out. I need to be able to build a regular expression in js that allows letters, numbers and symbols such as plus (+) just after the ?s=...

right now I'm trying something like this

var regexp = '^[a-z0-9]';
if (url == 'https://digitalswitch.cl/rileditores/?s=' + regexp){
   //do something
}else{
   //do something else
}

see [`.match()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/match) and fix your regex, it's not valid as it stand right now. — empiric, Jan 25 '18 at 12:53

var str     = "https://digitalswitch.cl/rileditores/?s=sample";
var matches = str.match(/\?s=([^&]*)/);
if(matches){
   alert('matched');
}else{
   alert('not matched');
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

The following example will search "?s" is available at the link or not. If yes alert "matched", else "not matched".

Hope this will helps you.
