所以这是一种特殊情况 - 我有一个插件,我无法根据合同原因进行修改。它显示一组下拉菜单,我需要它来显示一组单选按钮。是否有js / jquery方法将下拉列表转换为单选按钮,而无需更改HTML。记住,我可以添加内容 - 我可以直接修改插件(以及HTML)。
我知道这是一个不好的方法,相信我,我不喜欢它比你做的更多。
可能通过检测下拉选项的值然后将它们重新格式化为单选按钮,隐藏原始下拉列表?

隐藏下拉列表并将新的无线电元素放在表单之外,不需要发布,只需更新下拉列表值。
<强> Here is a code example on jsFiddle. 强>
$("#d option").each(function(i, e) { // get the options
$("<input type='radio' name='r' />") // create a radio element
.attr("value", $(this).val()) // set the value
.attr("checked", i == 0) // check the first by default
.click(function () { // add event click which updates the dropdown
$("#d").val($(this).val()); // update the dropdown if clicked
})
.appendTo("#r"); // append to some visible place
});

为了将它封装到一个声明属性中,我将@BrunoLM的函数扩展为使用给定的CSS类将所有&lt; select&gt;的样式设置为单选按钮外观。
