jQuery:removeClass 中的通配符类选择器

Question

当我直接指定它时(即“ratingBlock”、“ratingBlock1”、“ratingBlock2”等)，此代码片段可在添加新类之前删除现有类。但是当我在removeClass('[class ^ =“ratingBlock”]')中使用通配符选择器时，它不起作用。难道我做错了什么？谢谢。

<style type="text/css">
.ratingBlock {background:gold !important;}
.ratingBlock1, .ratingBlock2, .ratingBlock3, .ratingBlock4, .ratingBlock5 {background:LightGreen;}
</style>

<div class="test block ratingBlock">
Broken
<div><a href="#" class="ratingLink ratingNo-1">1+</a></div>
<div><a href="#" class="ratingLink ratingNo-2">2+</a></div>
<div><a href="#" class="ratingLink ratingNo-3">3+</a></div>
</div>

<script type="text/javascript">
// <![CDATA[
jQuery(document).ready(function(){
    initRatingWorks();
});

function initRatingWorks() {
    jQuery("a.ratingLink").bind('click', function() {
      var star = jQuery(this);
      var ratingBlock = star.parents('div.test.block');
      var rating = star.attr('class').match(/\d+/);

      if (ratingBlock.attr('class').indexOf('ratingBlock') !== -1) {
          ratingBlock.removeClass('[class^="ratingBlock"]').addClass('ratingBlock' + rating);
      }
      else {
          ratingBlock.addClass('ratingBlock' + rating);
      }

      return false;
    });
}
// ]]>
</script>

$.removeClass() 不将选择器作为参数，仅将类名(或多个类名)作为参数。

参见:Removing multiple classes (jQuery)

所以你基本上需要调用:

$.removeClass('ratingBlock1 ratingBlock2 ratingBlock3 ratingBlock4 ratingBlock5');
