I'm practicing if statements and I'm trying to make a calculator. I can enter the numbers but clicking on the add, subtract, multiply or divide buttons does not give me any results. I know there are easier ways to do it but it was just for practice. What have I done wrong?
function operar(boton) {
var num1, num2, resultado;
num1 = document.getElementById("num1");
num2 = document.getElementById("num2");
resultado = document.getElementById("resultado");
if (boton.value == '+') {
resultado.value = Number(num1.value) + Number(num2.value);
} else {
if (boton.value == '-') {
resultado.value = Number(num1.value) - Number(num2.value);
} else {
if (boton.value == '*') {
resultado.value = Number(num1.value) * Number(num2.value);
} else {
if (boton.value == '/') {
resultado.value = Number(num1.value) / Number(num2.value);
}
}
}
}
}<form>
<div>
<label>Número 1</label>
<input id="num1" type="text" />
</div>
<div>
<label>Número 2</label>
<input id="num2" type="text" />
</div>
<input type="button" value="+" onclick="operar(this)" />
<input type="button" value="-" onclick="operar(this)" />
<input type="button" value="*" onclick="operar(this)" />
<input type="button" value="/" onclick="operar(this)" />
<div>
<label>Resultado</label>
<input type="text" id="resultado" />
</div>
</form>The snippet you gave here, this code is running perfectly. What else do you want to do?
