使用按鈕來引用單選按鈕選項

-2

我的JavaScript是用psydocode編寫的，因爲我用正確的語法解決了大量的問題。

如果玩家沒有死亡，3000英里需要是一個每次點擊按鈕時都會明顯改變的值。

我需要弄清楚將播放按鈕鏈接到單選按鈕選項的語法，檢查用戶是否隨機死亡 - 如果沒有 - 從需要旅行的總英里數減去500英里（3000），然後檢查里程計數器是否爲0.

謝謝你的時間！

    some tracks have a better chance to reach Oregon than others! 
    After strategically choosing a track, click the button to travel 500 miles.

你的HTML有不匹配的''和''標籤。能否請您另外修復它，並縮進更好？ – Telokis 2015-03-03 04:11:42

，沒有真正的問題在這裏。是你希望我們爲你寫代碼嗎？我不明白。 – Telokis 2015-03-03 04:12:34

分享你有什麼特權d（myFunction） - 嘗試通過編輯http://jsfiddle.net/arunpjohny/r4qbkm2L/5/來創建演示 – 2015-03-03 04:15:14

function myFunction = If Track_1 = "checked" 

then 

Math.Random()<=.25 then alert(The Coal Train died by falling through a bridge!) 

else 
    var Miles 
    var OneTurn 
    var Total = "Miles"-"One Turn" 

if var Miles = 0 

then alert(Your Coal Train made it too Oregon! Congrats!);

下面是語法的JS代碼

function myFunction() { 
    if(document.getElementById('Track_1').checked) { 
     if(Math.random()<=.25) { 
      alert("The Coal Train died by falling through a bridge!"); 
     } 
     else { 
      var Miles; 
      var OneTurn; 
      var Total = Miles-OneTurn; 
      if(Miles==0) { 
      alert("Your Coal Train made it too Oregon! Congrats!); 
      } 
     } 
    } 
}

要調用函數的方法是正確的。所以，當按鈕被點擊，該代碼檢查「＃Track_1」輸入（單選框）...

雖然我寫的代碼，我已經建立了基於該的if-else階梯層次在psydocode提供「縮進」
