How do i check if my string contains certain words

Question

i'm trying to check if my url contains the word brand. as you can see i put my url into the variable url and now i want to check if that variable contains the word brand and replace it. My only problem is that i can't seem to find the code to check if it contains the word brand.

How do i do this?

<button onclick="myFunction()">navigate</button>
<script>
   function myFunction() 
   {
       var url = document.URL;
       if (window.location.href.match(brand)) 
       {
           alert('yes');
       }
       url = url.replace('.html','.php')
       window.location.href = url;o
    }
</script>

It should work like that

<button onclick="myFunction()">navigate</button>
<script>
   function myFunction() 
   {
       var url = document.URL;
       if (window.location.href.indexOf('brand') > -1) 
       {
           alert('yes');
       }
       url = url.replace('.html','.php')
       window.location.href = url;
    }
</script>

var url = "http://www.testsbrand.com";

There are two ways can do

RegExp

(new RegExp('brand')).test(url)

// or

/brand/.test(url)

indexOf:

url.indexOf('brand') !== -1
