Hi, I’m trying to take the value of a button and put it into a variable, but it doesn’t seem to help at all?

///HTML
<button class="teclado" id="qTeclado" onClick="clickTeclado(this.value);" value="Q">Q</button>
//JS
var letra = function clickTeclado(letra) {
document.getElementById('qTeclado').onClick = letra;
alert(letra);
}
javascript

You’re mixing the code a little bit, it’s simpler:

function clickTeclado(letra) {
  alert(letra);
}
<button class="teclado" id="qTeclado" onClick="clickTeclado(this.value);" value="Q">Q</button>

That is: the function clickTeclado has to be declared, and then you pass the this.value as argument. So, within the function, you already have the value you want in the parameter letra function. In this section you do not need the id button because you are calling the function directly on onclick with the value.
