Make Callback run directly

I took a Bootbox API just for the prompt, but the problem is that this syntax has a callback and with that, it only executes the code the second time I click on the button. Logically, I wanted it to run on the first click. (with the prompt normal in Javascript works as I want, but it’s horrible this prompt)

Follows the code:

function valida2(){
  bootbox.prompt({
    title: "This is a prompt with a number input!",
    inputType: 'number',
    callback: function (result) {
         Tips = parseInt(result);
         console.log(Tips);


    }
});
}


//a função que chama esse prompt
function ccck(){ 

 valida2();
 myArray[count] = [count + 1, 1 , Tips, "-"];
 sum += Tips;  
}
javascript

  • the question is that the code continues, "does not wait to execute the callback". I guess I still don’t quite understand how it works, so I’m not being able to implement

Like you said and right "the question is that the code continues", so you need to redirect the application flow to continue after callback:

function valida2(done) {
  bootbox.prompt({
    title: "This is a prompt with a number input!",
    inputType: 'number',
    callback: done
  });
}


//a função que chama esse prompt
function ccck() {

  valida2(function(result) {
    // o fluxo da aplicação continua aqui:
    var Tips = parseInt(result);
    myArray[count] = [count + 1, 1, Tips, "-"];
    sum += Tips;
  });

}

So your code stays inside the callback, that is when the result is available.
