递增然后递减10

Question

我正在构建一个幻想应用程序草稿。由于每10次选中一次，球队就会倒退。有一个简单的方法来做到这一点，或者我需要写一个长的if/else，switch，ext statment吗？

例如：

• 皮克队
• 1 - 1
• 2 - 2
• 3 - 3
• 4 -4
• 5 - 5
• 7 - 7
• 8 - 8
• 9 - 9
• 10 - 10
• 11 - 10
• 12 - 9
• 等

Answer 1

使一个布尔变量存储天气我们递增或递减，则一个字节存储您已增加/减少的次数，并进行循环。对布尔值使用if/else。不要忘记每次翻转布尔值。

Answer 2

像这样的东西应该把工作做好：

var total_picks = 100; 
var current_pick = 1; 
var current_team = 1; 
var my_test = true; 

for (var i = 0; i < total_picks; i++) { 

    // In this "if" statement, the team number will count up from 1 to 10 
    if (my_test) { 

    // Do whatever you want to with the current pick here 
    current_pick++; 

    // Do whatever you want to with the current team here 
    current_team++; 

    if (current_team == 10) { 
     my_test = false; 
    } 
    } else { 
    // In this "else" statement, the team number will count down from 10 to 1 

    // Do whatever you want to with the current pick here 
    current_pick++; 

    // Do whatever you want to with the current team here 
    current_team--; 
    if (current_team == 0) { 
     my_test = true; 
    } 
    } 
}
