它应该提出问题，然后让用户回答并返回最接近的楼梯。请帮忙。

这

不起作用：

if {
   Room = [113, 111, 115, 117, 205, 211, 215, 217, 309, 313, 311, 315, 317, 321]
   console.log(“The Staircase Closest To Your Room Is Staircase A”)
};

您可能希望：

if ([113, 111, 115, 117, 205, 211, 215, 217, 309, 313, 311, 315, 317, 321].indexOf(Room) !== -1) {
    console.log("The Staircase Closest To Your Room Is Staircase A");
}

此外，它必须在<script type="text/javascript">内部，而不是<style>

当您的 JS 代码属于 script 标签时，它位于 style 标签内。
您的 if 语句编写不正确。条件需要位于 if 关键字之后和大括号之前的括号内。
不是数字的房间应该被字符串化。

当它提示您要查找的房间时，它不会接受字符串吗？在这种情况下，您可能希望让 if 语句查找字符串。喜欢这个：

    if {
   Room = ["113", "111", "115".....(rest of them like this)]
   console.log(“The Staircase Closest To Your Room Is Staircase A”)
};
