如何使用JQuery解除对hover事件的绑定

这个问题是在JQuery的帮助下解除特定元素的悬停效果。在这里，我们使用2个JQuery方法.unbind()和.off()方法。这里讨论了一些技术。

方法:

选择需要解除绑定的悬停效果的元素。（确保悬停效果只能由JQuery添加，由CSS添加的悬停效果在这里不起作用）。
使用.unbind()或.off()方法。
传递我们想为该特定元素关闭的事件。

例子1：这个例子使用.unbind()方法

    <script>
        var el_up = document.getElementById("GFG_UP");
        var el_down = document.getElementById("GFG_DOWN");
        var heading = document.getElementById("h1");
        var div = document.getElementById("div");
        
        el_up.innerHTML = 
          "Click on the button to unbind the hover from the element.";
        
         $("#div").hover(function() {$ (this).css("background-color", "blue");
        }, function() {
             $(this).css("background-color", "green");         });            function gfg_Run() {$ ('#div').unbind('mouseenter mouseleave');
            el_down.innerHTML = "Hover effect Unbinded.";
        }
    </script>
</body>
  
</html>

输出:

在点击按钮之前。
在悬停在该元素上。
点击该按钮后。
