Question

我的代码中有这样的广播组：

<div id="question_1">
    <label for="q1_1a"><input name="q[1][1]" id="q1_1a" type="radio">A</label>
    <label for="q1_1b"><input name="q[1][1]" id="q1_1b" type="radio">B</label>
    <label for="q1_1c"><input name="q[1][1]" id="q1_1c" type="radio" data-target="#q1_2">Other</label>
        <input id="q1_2" name="q[1][2]" type="text" placeholder="specify">
</div>
<div id="question_2">
    <label for="q2_1a"><input name="q[2][1]" id="q2_1a" type="radio">A</label>
    <label for="q2_1b"><input name="q[2][1]" id="q2_1b" type="radio">B</label>
    <label for="q2_1c"><input name="q[2][1]" id="q2_1c" type="radio" data-target="#q2_2hide">Other</label>
    <div id="q2_2hide">
        Specify:
        <input name="q[2][2]" type="text">
    </div>
</div>

依旧......

当我检查包含data-target属性的单选按钮时，我试图编写将显示数据目标字段的jquery代码。到目前为止，我有这样的事情：

$('input[type="radio"][data-target]').change(function () { 
    $($(this).data('target')).toggle($(this).is(':checked'));
});

它会显示字段，但是一旦您选择了其他选项，它就不会隐藏它。有什么想法吗？

那是因为onchange事件仅在检查时针对单选按钮触发，而不是在未选中时触发。以下是处理预期行为的更通用方法：
