javascript - 是否可以根据以前的单选按钮限制单选按钮的选择？

Question

基本上我有一个调查，我希望人们根据重要性对 5 个项目进行 1-5 的排名。

这是 HTML:http://jsfiddle.net/madcaesar/jj8ky/

<form>
    <table>
    <tr>
                    <th colspan="2" class="altTH" style="text-align:left">Please rank, in order of most important (1) to least important (5)</th>
                  </tr>
                  <tr>
                    <th><label>Professionalism (promoting the profession of medicine)</label></th>
                    <td>

一旦 1 被选中一次，jQuery 是否有可能使 1 不可用？和 2 一旦选择了 2 等等？现在他们可以选择他们想要的任何数字，我想不出办法做到这一点。

Answer 1

如果你选择了一个特定的数字，它会取消选择任何其他具有相同值的东西？:

http://jsfiddle.net/jj8ky/2/

$("#radio_table").on("click", ".checkbox", function () {
    var $this = $(this);
    var all = $("#radio_table").find(".checkbox").not($this);
    var val = $this.val();

    if ($this.prop("checked") === true) {
        all.filter(function () {
            return $(this).val() === val;
        }).prop("checked", false);
    }
});
