<a id="btnExcellent" class="btn btn-primary" href="javascript:__doPostBack(&#39;btnExcellent&#39;,&#39;&#39;)">Excellent</a>
<a id="btnFine" class="btn btn-primary" href="javascript:__doPostBack(&#39;btnFine&#39;,&#39;&#39;)">Fine</a>
<a id="btnBad" class="btn btn-primary" href="javascript:__doPostBack(&#39;btnBad&#39;,&#39;&#39;)">Bad</a>
<a id="btnSkip" class="btn btn-primary" href="javascript:__doPostBack(&#39;btnSkip&#39;,&#39;&#39;)">Skip</a>

要求：

当我单击第一个单选按钮（即值为one）时，我想禁用btnFour按钮。如果我单击剩余的两个单选按钮，我希望前三个按钮被禁用，除了最后一个。

它不像我想要的那样工作。如果我采用简单的 HTML 按钮，那么它可以工作，但在 LinkBut​​tons 的情况下它不起作用。任何帮助将非常感激。

谢谢你。

您可以尝试下面的代码，只需在调用禁用函数时传递单选按钮的值并启用或禁用相关按钮

代码片段

function disableButtons(val) {
   if (val == 'clear') {
     $('#btnExcellent, #btnFine, #btnBad').addClass('disabled');
     $('#btnSkip').removeClass('disabled');
   } else {
     $('#btnExcellent, #btnFine, #btnBad').removeClass('disabled');
     $('#btnSkip').addClass('disabled');
   }
   
   $('a.disabled').each(function(){
      var href = $(this).attr('href');
      //console.log('attr = ' + href);
      $(this).data('href', href);
      $(this).attr('href', '#')
   });
   $('a:not(.disabled)').each(function(){
      var href = $(this).data('href');
      //console.log('data = ' + href);
      if(href) {
         $(this).attr('href', href);
      }
   });
}

a.disabled {
  opacity: 0.1;
}
