為什么我的Javascript價格計算器不起作用？

Question

我無法讓下面的腳本工作，我真的不明白為什么。 應該工作正常

每個變量都被考慮在內，但沒有價格出現？

}

function hideTotal()
{
    var divobj = document.getElementById('totalPrice');
    divobj.style.display='none';
}

我應該感謝javascript-coder.com的腳本模板，我試圖適應。

Answer 1

SpeakPrice = speak_prices[selectedSpeak.value];

未定義selectedSpeak變量。 根據您的要求定義它。

Answer 2

你在哪里

var selectedDage = theForm.elements["speak"];

它應該是

var selectedSpeak = theForm.elements["speak"];

否則selectedSpeak沒有在任何地方定義。
