Pass parameter in method

Question

I have this code

var txt;

function change(){
    txt = "@Utils.GeneratePass()";      
    document.getElementById("password_field").value = txt;   
}

function changeToHash(txt){
      alert(window.txt);
      var password = "@Utils.Hash(txt)";
      document.getElementById("password_field").value = password;        
}

In method @Utils.Hash i need pass one string, and i want put the value of txt. But i got the error "The name 'txt' does not exist in the current context.

You might want to have another look at how variables work. Also get rid of that legacy `var` and use `let` and `const` instead. — Andreas, Feb 04 '22 at 15:23
@jarmod Utils is one static class where i have the method Hash — Marco, Feb 04 '22 at 15:28
Right, but is this some UI framework that allows you to inject function calls into HTML input elements? Which framework? You didn't tag anything but javascript. — jarmod, Feb 04 '22 at 15:34
@Ameer Like this? var password = "@Utils.Hash('${txt}')" i got the error "Too many characters in character literal" — Marco, Feb 04 '22 at 15:35
@Andreas yes, i change to let but i want pass variable txt in var password = "@Utils.Hash('${txt}')"" — Marco, Feb 04 '22 at 16:51

You cannot pass js variable to C# code,you can try to pass @Utils.GeneratePass() to @Utils.Hash():

var txt;

function change(){
    txt = "@Utils.GeneratePass()";      
    document.getElementById("password_field").value = txt;   
}

function changeToHash(txt){
      alert(window.txt);
      var password = "@Utils.Hash(Utils.GeneratePass())";
      document.getElementById("password_field").value = password;        
}
