尝试按照

中的文档建议创建垂直导航栏

https://react-bootstrap.github.io/components/navs/

const navInstance = (
    <Nav bsStyle="pills" stacked activeKey={1} onSelect={handleSelect}>
        <NavItem eventKey={1} href="/home">
            NavItem 1 content
        </NavItem>
        <NavItem eventKey={2} title="Item">
            NavItem 2 content
        </NavItem>
        <NavItem eventKey={3} disabled>
            NavItem 3 content
        </NavItem>
    </Nav>
);

但看起来堆叠关键字什么也没做,导航显示为水平: The result I got

这就是它应该是这样的: Snapshot of docs 我做错了什么?

您需要显式添加bootstrap css。 Bootstrap Guide for react

将以下链接添加到您的public / index.html

public class GeneratedNums {

public static void main(String[] args) {

    int [] numbers = new int [101]; 

    for ( int x=0; x < 101; x++){
        numbers[x] = sumDigits (x);


    }

    for ( int x=0; x < numbers.length; x++){
        System.out.println(x + ": " + numbers[x]);
    }


}

public static int sumDigits ( int num) {

   int sum = num;

   while ( num != 0){
       num += num%10;
       num /= 10;
   }
      return num;
}
}
