如何在jQuery中捕获选中的单选按钮的标签

Question

我有这个标记块：

<fieldset class="form__list form__inlineButtons" enabled="enabled">
<label for="paymentMethod_839838" class="form__optional">
<input type="radio" value="1" name="paymentMethod" id="paymentMethod_839838" class="form__list jq__pmt1" style="display: inline-block;"> Cash
</label>
<label for="paymentMethod_570709" class="form__optional">
<input type="radio" value="2" name="paymentMethod" id="paymentMethod_570709" class="form__list jq__pmt2" style="display: inline-block;"> Check
</label>
<label for="paymentMethod_692392" class="form__optional">
<input type="radio" value="3" name="paymentMethod" id="paymentMethod_692392" class="form__list jq__pmt3" style="display: inline-block;"> Credit Card
</label>
<label for="paymentMethod_567739" class="form__optional">
<input type="radio" value="4" name="paymentMethod" id="paymentMethod_567739" class="form__list jq__pmt4" style="display: inline-block;"> Invoice
</label>
<label for="paymentMethod_227750" class="form__optional">
<input type="radio" value="5" name="paymentMethod" id="paymentMethod_227750" class="form__list jq__pmt5" style="display: inline-block;"> Payment Pending
</label>
</fieldset>

我有这个jQuery的：

$('[name="paymentMethod"]').change(function() {
alert( $('[name="paymentMethod"] :radio:checked + label').text() );
}); // end .change()

我似乎无法捕获选中的单选按钮的标签

你会这样做-

$('[name="paymentMethod"]').change(function() {
    var label = $(this).closest('label').text();
    alert(label);
}); // end .change()
