试试这个：

<script type="text/javascript"> 
$( document ).ready(function() {
  $("input:radio").click(function() {
    if($(this).val() == "head") {
      $("#head").show();
      $("#bod").hide();
    } else {
      $("#head").hide();
      $("#bod").show();
    }
  });
});
</script>

<input type="radio" name="opt" value="head"> HEAD
<input type="radio" name="opt" value="bod"> BOD

<div id="head" style="display:none;">Head</div>
<div id="bod" style="display:none;">BOD</div>

Answer 3

我们走了：

jQuery的：

    <script>
        $('#disable').on('click', function() {
            $('.demo').disable();
        });
        $('#enable').on('click', function() {
            $('.demo').enable();
        });
    </script>

CSS：

        <style>
         div.disabled {
        background: lightgrey;
    }
        </style>

Answer 4

这个应该可以解决问题：

<script type="text/javascript">
$( document ).ready(function() {
$('input[type=radio]').click(function(){


    if (this.previous) {
        this.checked = false;
        document.getElementById("nc").style.display = "block";
        this.previous=false;
    }
   else {
        this.previous = this.checked;
        document.getElementById("nc").style.display = "none";
    }

});});
