单击的第二个项目无法正常工作

Second item clicked does not function properly

本文关键字：常工作 工作 第二个 项目 单击      更新时间：2023-09-26

我创建了一个jquery代码，由于某种原因，它第一次工作，但第二个项目点击与其余项目交错，而点击的第一个项目仍然可见。这很奇怪。实际上，我设置变量并使用它们的方式应该意味着只有单击的项目会保留，而其他项目会错开。

知道发生了什么吗？

在这里，您可以在其中看到操作中的代码：http://jsfiddle.net/HCY5m/33/

我的JavaScript代码：

  var children = $('.icons').children();
  var icons = new TimelineLite({paused:true});
children.click(function(event) {
      var siblings = $(this).siblings()
      span = $(this).find("span").first()
      content = $(this).find("div")
      h1 = content.find("h2")
      li = content.find("li")
      clicks =  $(this).data('clicks');
      icons.staggerTo(siblings, 1.3, {left:"-150%", ease:Back.easeIn}, 0.1)
  if (clicks) {
     TweenMax.to(span, 1, {opacity:0, ease:Power2.easeInOut})
     TweenMax.to(content, 1, {display:"none", delay:1.5, ease:Power2.easeInOut})
     TweenMax.to(h1, 1, {opacity:0, ease:Power2.easeInOut})
     TweenMax.to(li, 1, {opacity:0, ease:Power2.easeInOut})
     setTimeout(function(){ icons.reverse(); }, 500);
  } else {
     TweenMax.to(span, 1, {opacity:0, delay:1.5, ease:Power2.easeInOut})
     TweenMax.to(content, 0, {display:"block", delay:1.5, ease:Power2.easeInOut})
     TweenMax.to(h1, 1, {opacity:1, delay:1.5, ease:Power2.easeInOut})
     TweenMax.to(li, 1, {opacity:1, delay:1.5, ease:Power2.easeInOut})
     TweenMax.to(this, 1, {width:"46%", top:"2em", left:"-2%", delay:1.5, ease:Power2.easeInOut})
     icons.play()
  }
  $(this).data("clicks", !clicks);
});

我能够烹饪的东西。看看我在这里创建的JSFiddle，如果有什么不清楚的地方，请告诉我。以下是相同的JavaScript代码，无需更改HTML或CSS中的任何内容：
