JavaScript - removeClass 不工作？

Question

我有一个 jssor 画廊，我通过添加 CSS 类“blur”对其进行了模糊处理。当用户点击 div 时，我想“取消模糊”这个画廊。为此，我添加了这个简单的 JS 代码:

    jQuery(document).ready(function($) {
      $("js1").click(function(){
        $("jssor_1").removeClass("blur");
      });
    });

其中“js1”是我的 div 的 ID，“jssor_1”是我的画廊的 ID。不幸的是，这根本不起作用。我是 JS 的新手，但我认为这应该可以正常工作，因为点击功能会检查是否点击了 HTML 元素...这是我的图库的 HTML 代码:

  <div id="gallery" class="section gallery-section">
    <div class="container-fluid">
      <div id="jssor_1" class="blur" style="top: 0px; left: 0px; width: 800px; height: 445px; overflow: hidden; visibility: hidden; background-color: #000;">
        <div data-u="slides" style="cursor: default; top: 0px; left: 0px; width: 800px; height: 400px; overflow: hidden;">
          <div data-p="144.50" style="display: none;">
            <img data-u="image" src="img/realizacje/01.jpg" />
            <img data-u="thumb" src="img/realizacje/01t.jpg" />
          </div>
          ...other gallery images...
        </div>
        <div data-u="thumbnavigator" class="jssort01" data-autocenter="1">
          <div data-u="slides" style="cursor: default;">
            <div data-u="prototype" class="p">
              <div class="w">
                <div data-u="thumbnailtemplate" class="t"></div>
              </div>
              <div class="c"></div>
            </div>
          </div>
        </div>
        <span data-u="arrowleft" class="jssora05l" style="top: 158px; left: 8px; width: 40px; height: 40px;"></span>
        <span data-u="arrowright" class="jssora05r" style="top: 158px; right: 8px; width: 40px; height: 40px;"></span>
      </div>
      <div id="js1" class="naglowekgalerii">PRZYKŁADOWE REALIZACJE</div>
    </div>
  </div>

JQuery 选择器
JQuery 选择器是一种选择文档对象模型 (DOM) 元素的方法，即 HTML 元素，如 div、button .. 等

' * '

$("*")  //All elements  

#id

$("#lastname")  //The element with id="lastname"  

.class

$(".intro") //All elements with class="intro"  

.class,.class

$(".intro,.demo")   //All elements with the class "intro" or "demo"

元素

$("p")   //All <p> elements

el1,el2,el3

$("h1,div,p")   //All <h1>, <div> and <p> elements

你的情况

您使用的选择器不正确，您需要使用

jQuery(document).ready(function() {
  $("#js1").click(function(){
    $("#jssor_1").removeClass("blur");
  });
});
