打印出多个答案的代码

我正在为我的JScript类做一些东西，我看不到我的代码是如何打印我的document.write的多个实例的。任何帮助？打印出多个答案的代码

memberNumber = prompt("How many people will be staying?"); 
memberOfAAA = prompt("Are the members part of AAA?"); 
roomView = prompt("Do you want a room with a view?"); 
Number(memberNumber); 

if(memberOfAAA === "yes" || "Yes", memberNumber > 5 && memberNumber < 3, roomView === "yes") 
{ 
roomCost = (costRoom12 - (costRoom12 * percent1)+(costRoom12 * viewCost)); 
document.write("Total cost per night is $" + roomCost); 
}if (memberOfAAA === "yes" || "Yes", memberNumber > 5 && memberNumber < 3, roomView === "no" || "No") 
{ 
roomCost = (costRoom12 - (costRoom12 * percent1)); 
document.write("Total cost per night is $" + roomCost);} 

if(memberOfAAA === "no" || "No" , memberNumber > 5 && memberNumber < 3, roomView === "yes" || "Yes") 
{ 
roomCost = (costRoom12 + (costRoom12 * viewCost)); 
document.write("Total cost per night is $" + roomCost); 
}if(memberOfAAA === "no" || "No" , memberNumber > 5 && memberNumber < 3, roomView === "no" || "No") 
{ 
roomCost = (costRoom12); 
document.write("Total cost per night is $" + roomCost); 
} 
if (memberOfAAA === "yes" || "Yes", memberNumber > 5 && memberNumber < 3, roomView === "yes" || "Yes") { 
roomCost = (costRoom34 - (costRoom34 * percent2) + (costRoom34 * viewCost)); 
document.write("Total cost per night is $" + roomCost); 
} 
if (memberOfAAA === "yes" || "Yes", memberNumber > 5 && memberNumber < 3, roomView === "no" || "No") { 
roomCost = (costRoom34 - (costRoom34 * percent2)); 
document.write("Total cost per night is $" + roomCost); 
} 
if(memberOfAAA === "no" && memberNumber > 5 && memberNumber < 3, roomView === "yes" || "Yes") { 
roomCost = (costRoom34 + (costRoom34 * viewCost)); 
document.write("Total cost per night is $" + roomCost); 
} 
if(memberOfAAA === "no" || "No", memberNumber > 5 && memberNumber < 3, roomView === "no" || "No") { 
roomCost = costRoom34; 
document.write("Total cost per night is $" + roomCost); 
} 
if(memberOfAAA === "Yes" || "yes", memberNumber > 7 && memberNumber < 4, roomView === "yes" || "Yes") { 
roomCost = (costRoom56 - (costRoom56 * percent3) + (costRoom56 * viewCost)) 

} 
if(memberOfAAA === "yes" || "Yes", memberNumber > 7 && memberNumber < 4, roomView === "no" || "No") { 
roomCost = (costRoom56 - (costRoom56 * percent3)); 
document.write("Total cost per night is $" + roomCost); 
} 
if(memberOfAAA === "no" || "No", memberNumber > 7 && memberNumber < 4, roomView === "yes" || "Yes") { 
roomCost = (costRoom56 + (costRoom56 * viewCost)); 
document.write("Total cost per night is $" + roomCost); 
} 
if(memberOfAAA === "no" || "No", memberNumber > 7 && memberNumber < 4, roomView === "no" || "No") { 
roomCost = (costRoom56); 
document.write("Total cost per night is $" + roomCost); 
}

它应该只打印一个字符串，如变量一个输入所定义的那样，但它打印出所有的字符串。

你应该发布一些代码。 – austin 2013-04-08 17:58:38

woops，忘了那部分，修好了 – ectoBiologist 2013-04-08 17:59:34

你的if语句总是评估为true，因为

if (memberOfAAA === "yes" || "Yes" ...)

应该

if (memberOfAAA === "yes" || memberOfAAA === "Yes" ...)

而且你应该使用if/else if语句。
