innerHTML不更改div輸出

Question

我試圖根據用戶單擊的單選按鈕顯示文本區域。 當注釋掉“競賽”功能時，新聞稿部分可以正常工作。 但是，當包含競賽功能時，新聞通訊將不起作用。 我嘗試調試，但是似乎找不到問題。 我嘗試使用不同的形式，但不會改變問題。

我的HTML：

 function newsletter() { var response = ""; if(document.getElementById("yes").checked) { response += "<p><b>Enter Your Address:</b></p>"; response += '<input type="text" id="address"><br>'; var output = document.getElementById("isChecked"); output.innerHTML = response; } } function contest() { var resp = ""; if(document.getElementById("answer").value == "Y") { resp += "<p><b>Enter your credit card information to verify age ($0.00 charge)</b></p>"; resp += "<br>"; resp += '<input type="text" id="first4" size="4" maxlength="4">'; resp += "-"; resp += '<input type="text" id="second4" size="4" maxlength="4">'; resp += "-"; resp += '<input type="text" id="third4" size="4" maxlength="4">'; resp += "-"; resp += '<input type="text" id="fourth4" size="4" maxlength="4"'; var out = document.getElementById("contestOutput"); out.innerHTML = resp; } } 

 body {background-color: pink; }
