为什么在THIS CODE中按下＆＃34;我＆＃34;第一次工作时右下角的按钮，但第二次只显示粉红色的背景？

＆＃13;
＆＃13; 
(function(){
  'use strict';

  var $mainButton = $(".main-button"),
      $closeButton = $(".close-button"),
      $buttonWrapper = $(".button-wrapper"),
      $ripple = $(".ripple"),
      $layer = $(".layered-content");

  $mainButton.on("click", function(){
    $ripple.addClass("rippling");
    $buttonWrapper.addClass("clicked").delay(1500).queue(function(){
      $layer.addClass("active");
    });
  });

  $closeButton.on("click", function(){
    $buttonWrapper.removeClass("clicked");
    $ripple.removeClass("rippling");
    $layer.removeClass("active");
  });

})();

2 个答案:

答案 0 :(得分：2)

您必须使用clearQueue()函数清除队列。

将您的代码更改为此

...
    $buttonWrapper.addClass("clicked").clearQueue().delay(1500).queue(function(){
            $layer.addClass("active");
        });
    });
...

或者你甚至可以这样做，这是jQuery文档中建议的方式。

$buttonWrapper.addClass("clicked").delay(1500).queue(function(){
            $layer.addClass("active");
            jQuery.dequeue( this );
        });
    });

重要直接来自jQuery文档，

  

请注意，在使用jQuery.queue（）添加函数时，我们应该确保   最后调用jQuery.dequeue（）以便下一个函数   在线执行。

答案 1 :(得分：1)

而不是：

$buttonWrapper.addClass("clicked").delay(1500).queue(function(){
   $layer.addClass("active");
});

使用此：

$buttonWrapper.addClass("clicked");
setTimeout(function(){$layer.addClass("active")},1500);

它会起作用。
