使用按鍵激活Javascript功能

Question

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 " 
} 
    } 

我想在按下「1」鍵時啓動此功能。如何做到這一點

Answer 1

window.onkeypress = function(event) { 
    if (event.keyCode == 41) { 
     // do a function 
    } 
} 

，而不是你可以看看的字符代碼的onkeydown /的onkeyup
