嗨！您是否在Chrome開發工具中檢查控制檯是否有錯誤？ –

請試試這個window.alert = null; alert（'test'）; // fail delete window.alert; // true alert（'test'）; // win –

form1從哪裏來？ –

變更功能validateInput

 

    function validateInput() { 
     userInput = new String(); 
     userInput = document.getElementById("i2").value; 

     if (userInput.match("Indica")) 
     document.getElementById('boldStuff').innerHTML = '(Note: This vehicle to be requested one hour before)'; 
     else if (userInput.match("Innova")) 
     document.getElementById('boldStuff').innerHTML = '(Note: This vehicle to be requested one hour before)'; 
     else if (userInput.match("Others")) 
     document.getElementById('boldStuff').innerHTML = '(Note: This vehicle to be requested one hour before)'; 
     else if (userInput.match("Tavera")) 
     document.getElementById('boldStuff').innerHTML = ''; 
     else if (userInput.match("Tempo")) 
     document.getElementById('boldStuff').innerHTML = ''; 
    }

Alsao當你在下拉的變化呼喚ValidateInput第二行，因爲沒有被傳遞不傳遞任何參數在函數聲明中
