的Javascript無法添加數字來我的計算器顯示屏
function one(event)
{
clearTimeout(timer);
timer=setTimeout("AddDigit(object)",500);
object=event;
}
//每次我鍵入一個數字我的顯示窗口它取代了以前數而不將它像一個實際的計算器會。也試圖弄清楚爲什麼我不能得到出現在我的顯示窗口我的函數符號....我懷疑它是與我的setTimeout ....
function AddDigit(x)
{
object=x;
if (eval(digit) == 0)
{digit = object;}
else
{digit = digit + object;}
document.calculator.display.value=object;
}
爲什麼使用計時器而不是立即調用AddDigit? – PherricOxide
