jquery - 如果使用 jQuery 检查单选按钮则显示框

Question

我有以下代码:

    <fieldset>
        <legend>Do you currently have SolidWorks</legend>

        <ul>
            <li><label for=""><input type="radio" name="solidworks" value="Yes" id="rdYes" /> Yes</label></li>
            <li><label for=""><input type="radio" name="solidworks" value="No" id="rdNo" /> No</label></li>
        </ul>
    </fieldset>

    <fieldset id="boxReseller" style="display:none;">
        <legend>Who is your SolidWorks reseller?</legend>
        <ul>
            <li><label for=""><input type="radio" name="reseller" value="Cad Connect" /> Cad Connect</label></li>
            <li><label for=""><input type="radio" name="reseller" value="Cadtek" /> Cadtek</label></li>
            <li><label for=""><input type="radio" name="reseller" value="CCSL" /> CCSL</label></li>
            <li><label for=""><input type="radio" name="reseller" value="Innova" /> Innova</label></li>
            <li><label for=""><input type="radio" name="reseller" value="NT CAD/CAM" /> NT CAD/CAM</label></li>
            <li><label for=""><input type="radio" name="reseller" value="Solid Engineer" /> Solid Engineer</label></li>
            <li><label for=""><input type="radio" name="reseller" value="Solid Solutions Ireland" /> Solid Solutions Ireland</label></li>
            <li><label for=""><input type="radio" name="reseller" value="Solid Solutions Management" /> Solid Solutions Management</label></li>
            <li><label for=""><input type="radio" name="reseller" value="TMS Scotland" /> TMS Scotland</label></li>
        </ul>

    </fieldset>

我想要做的是默认隐藏第二个字段集，如果一个人选择"is"，则该框将出现，如果他们选择“否”或未选择"is"，则该框将再次隐藏。

有人可以帮忙吗？谢谢。

你可以这样做:

$("input[name='solidworks']").change(function() {
  $("#boxReseller").toggle(this.value == "Yes");
});​​​​​​
$("input[name='solidworks']:checked").change(); //trigger correct state onload

You can give it a try with the markup in the question here ，然后尝试 pre-checked "Yes" version here .
