function addone()
{
document.getElementById("subtract").disabled=false;
x += 1;
document.getElementById("result").innerHTML="Doshi has said OK " + x + " times."
if(x == 1 ){
document.getElementById("resetall").disabled=false;
document.getElementById("reset").disabled=false;
document.getElementById("result").innerHTML="Doshi has said OK " + x + " time."
}
if(x == 0){
document.getElementById("resetall").disabled=true;
document.getElementById("reset").disabled=true;
document.getElementById("result").innerHTML="Doshi has not said OK "
}
}
I want to start this function when I press the "1" key. How do I do this

回答by tobspr
window.onkeypress = function(event) {
if (event.keyCode == 41) {
// do a function
}
}
instead of onkeypress you can look at onkeydown / onkeyup
您可以查看 onkeydown / onkeyup 而不是 onkeypress
