為什么前臺動態name值后臺獲取的value有雙引號呢？在頁面點擊radio時有時候有雙引號有時候就沒有雙引號。
<c:forEach items="${problems}" var="problem">
<tr>
<td>${problem.questionId}</td>
<td>${problem.title}</td>
<td>${problem.optionA}</td>
<td>${problem.optionB}</td>
<td>${problem.optionC}</td>
<td>${problem.optionD}</td>
<td>
<input type="radio" name="answer_${problem.questionId}" value="https://bbs.csdn.net/topics/A">A
<input type="radio" name="answer_${problem.questionId}" value="https://bbs.csdn.net/topics/B">B
<input type="radio" name="answer_${problem.questionId}" value="https://bbs.csdn.net/topics/C">C
<input type="radio" name="answer_${problem.questionId}" value=https://bbs.csdn.net/topics/D">D
</td>
</tr>
</c:forEach>

有的時候是取的你前端設定的默認值把：value=https://bbs.csdn.net/topics/Duj5u.com熱心網友回復：
<input type="radio" name="answer_${problem.questionId}" value="https://bbs.csdn.net/topics/C">C
<input type="radio" name="answer_${problem.questionId}" value=https://bbs.csdn.net/topics/D">D
你看2個代碼的長度都不一樣,一個2邊都有雙引號,一個只有一邊有
value="https://bbs.csdn.net/topics/C">C
value=https://bbs.csdn.net/topics/D">D
