Hello folks I am trying to make an automated freight selection in my shop, why the integrated shop platform does not offer specific freight option for products, so I have:
Conveyor: Only for T-shirts
Post Office: Masks and Mugs

So I wanted to locate the key words "T-shirt" and "Mascara"; in this way print the message warning the form of shipping that has available, disabling the other;

Facts: I was only able to locate with Document.indexof and IF and Else does not work; /

 
    function inicia() {    

   
   if (true) { 

         var nomeproduto=document.querySelector(".produto-info a").innerHTML
         
         var mask=nomeproduto.indexOf("Mascara");

          if (mask > 0) { 
            var firstfrete=document.querySelector(".formas-envio > ul > li:first-child");

            firstfrete.textContent = "Mascaras & Canecas somente por Correios!";
          } 

          else { alert("Frete Mascaras & Canecas Somente Correios"); }  
           } 

             else { alert("");} 
      
     

  if (true) { 
        
         
         var shirt=nomeproduto.indexOf("Camiseta");

          if (shirt > 0) {  

            var firstfrete=document.querySelector(".formas-envio > ul > li:last-child");

            firstfrete.textContent = "Camisetas exclusivamente Transportadora, Demais produtos apenas correios!";


          } 

          else { alert("Frete Camisetas Somente Transportadora"); }        

           } 

     else { alert("");}  

            }

-1

The index returns the initial position of the searched Text, if this text is at the beginning of the string it will return to position 0, when it finds nothing it returns -1.

In the case if should be as follows:

if(shirt != -1) {
 ...logica aqui
} else {
  ...
}
