不能將Nan轉換成Java.lang.long

Question

TimeoutInterval = TimeoutInterval * 60 * 1000; //Converting to milisecond 
TimeOutObj = setTimeout(function(){  

},TimeoutInterval); 

這裏有什麼問題，爲什麼我得到這個錯誤Cannot convert Nan to Java.lang.long。

Answer 1

嘗試

var TimeoutInterval = 1; 
    TimeoutInterval = TimeoutInterval * 60 * 1000; 

Answer 2

這樣做：

var TimeoutInterval = 1; 
TimeoutInterval = TimeoutInterval * 60 * 1000; //Converting to milisecond 
var TimeOutObj = setTimeout(function(){},TimeoutInterval);
