我有以下代码:
<div id="choices">
<div>
<input type="radio" name="question-answers" id="question-answers-A" value="A" onclick="this.form.submit();" />
<label for="question-answers-A">$c[0] </label>
</div>
<div>
<input type="radio" name="question-answers" id="question-answers-B" value="B" onclick="this.form.submit();"/>
<label for="question-answers-B">$c[1]</label>
</div>
</div>
选择收音机时会提交表格。
有没有办法在没有javascript的情况下执行此操作? (没有onClick)
感谢。

为什么不传统的提交输入?
<form>
<input type="radio" name="r1">
<input type="radio" name="r2">
<input type="submit" value="send" />
</form>
The form is submitted when a radio is selected.
Javascript是可以使用的方式或简单的旧HTML,但不会在更改时提交。

以下是在没有Javascript http://jsfiddle.net/DCHaT/8/
的情况下让它工作的示例您依赖CSS和标签。
CSS:
button.transparent{
position:absolute;
left:0;
right:0;
top:0;
bottom:0;
visiblity:hidden;
border:none;
z-index:2;
background-color:transparent;
}
div.radio{
position:relative;
}
div.radio > label > input[type="radio"]{
position:relative;
z-index:1;
}
代码:
<form action="http://www.yahoo.com" method="GET">
<div class="radio">
<label for="radio_1">
<button type="submit" class="transparent" name="radio" value="1"></button>
<input type="radio" value="1" name="radio" id="radio_1"/>
Radio 1</label>
</div>
<div class="radio">
<label for="radio_2">
<button type="submit" class="transparent" name="radio" value="2"></button>
<input type="radio" value="2" name="radio" id="radio_2"/>
Radio 2</label>
</div>
</form>

你可以使用php
<div class="field form-inline radio">
<label class="radio" for="txtContact">Preferred Method of Contact</label>
<input class="radio" type="radio" name="contact" value="email" checked /> <span>Email</span>
<input class="radio" type="radio" name="contact" value="phone" /> <span>Phone</span>
</div>
$contact = $_POST['contact']
//Will return either "email" or "phone".

使用两个提交按钮,并可选择将它们设置为单选按钮。 http://jsfiddle.net/trevordixon/FNzhb/3/
<form method="POST">
<button type="submit" name="question-answers" value="A">A</button>
<button type="submit" name="question-answers" value="B">B</button>
</form>
<style>
button {
border: none;
background: none;
padding-left: 10px;
cursor: pointer;
}
button:before {
content: '';
display: block;
width: 12px;
height: 12px;
border: 1px solid #999;
border-radius: 50%;
}
button:active:before { content: '•'; }
</style>
