将下拉列表转换为单独按钮，无需修改HTML [英] Convert dropdowns to radio buttons w/o modifying HTML

问题描述

所以这是一个例外情况 - 我有一个插件，我不能修改为合同的原因。它显示一组下拉列表，我需要它来显示一组单选按钮。是否有一个js / jquery方法将下拉列表转换为单选按钮，不改变HTML。记住，我可以添加东西 - 我可以直接修改插件（和HTML）。

So this is sort of an exceptional case situation - I have a plugin that I can't modify for contractual reasons. It displays a set of drop downs and I need it to display a set of radio buttons instead. Is there a js/jquery method for converting dropdowns to radio buttons w/o changing the HTML. Remember, I can add stuff - I just can modify the plugin (and thus the HTML) directly.

我认为这是一个糟糕的方法，相信我我不喜欢它比你更多。

I get that this is a bad way to do it, trust me I don't like it any more than you do.

可能通过检测下拉选项的值，然后将其重新格式化为单选按钮，隐藏原始下拉菜单？

Possibly by detecting the values of the drop-down options and then reformatting them as radio buttons, hiding the original dropdown?

推荐答案

隐藏下拉菜单，表格，则不需要发布，只需更新下拉值。

Hide the dropdown and place the new radio elements outside the form, they don't need to post, just update the dropdown value.

Here is a code example on jsFiddle.

$("#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
});
