Answer 1

首先要确保你的id是独一无二的..

用于prop()启用/禁用元素..(确保为您的单选按钮添加值...代码中缺少这个值)

HTML

<input type="radio" id="high" value="Y" name="high"  />
<input type="radio" id="high" value="N" name="high"  />

jQuery的

 $('input[name="high"]').change(function(){
      if($(this).val() == 'Y'){
         $('#date_biennial_budget').prop('disabled',false);
      }else{
         $('#date_biennial_budget').prop('disabled',true);
      }
 });
