我是Javascript的新手。我有一个这样的代码片段:
<ul class="dropdown-menu dropdown-menu-right" onchange="onCompChange()">
<div class="radio" id = "compSelect">
<label><input type="radio" name="optradio">op1</label>
</br>
<label><input type="radio" name="optradio">op2</label>
</br>
<label><input type="radio" name="optradio">op3</label>
</div>
</ul>
选择单选按钮时,我想知道选择了哪个选项(op1 / op2 / op3)。

要获取id为myForm的表单的所选radioName项的值:
$('input[name=radioName]:checked', '#myForm').val()
这是一个例子:
$('#myForm input').on('change', function() {
var value = $('input[name=radioName]:checked', '#myForm').val();
console.log(value);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="myForm">
<input type="radio" name="radioName" value="1" /> 1 <br />
<input type="radio" name="radioName" value="2" /> 2 <br />
<input type="radio" name="radioName" value="3" /> 3 <br />
</form>
认为这有助于你。

这个怎么样:
<input type="radio" name="opt radio" onclick="check(this.value)" value="op1" >op1</label>
<input type="radio" name="opt radio" onclick="check(this.value)" value="op2" >op2</label>
<input type="radio" name="opt radio" onclick="check(this.value)" value="op3" >op3</label>
你的.js中的:
function check(value) {
//... use your value
}
