我这里有一个问题。我这里有两个标签 'LB" 和 "medalTally' 。我需要在页面加载时默认显示第一个标签信息，当我单击第二个标签时它应该隐藏。我有一些代码。 谁能帮我看看我到底在哪里犯了错误。 

$(document).ready(function() {
  var _this = $('.tab a:first')
  var block = _this.attr('href');
  $('.tab a').on('click', function(e) {
    e.preventDefault();
    var _this = $(this);
    var block = _this.attr('href');
    if (block == "#leaderboard") {
      $(block).fadeIn();
      $('#login').hide();
    }
    if (block == "#login") {
      $(block).fadeIn();
      $('#leaderboard').hide();
    }
  });
});

只需在 javascript 中添加一行：

它将点击 $(document).ready 上的活动选项卡

您只能在打开的单击事件中插入 文档就绪

我尝试解决您的第二个错误。 当您单击第二个 div 时，活动类不存在。这是解决以下问题的代码

首先删除 active 类，然后在单击 div 时添加活动类。

脚本 

$(document).find('.active').removeClass("active");
$(this).parent().addClass( "active" );

现场演示 这里

下面的代码片段示例 

$(document).ready(function(){
				$('.tab a').on('click',function(e){
					e.preventDefault();
          var _this = $(this);
					var block = _this.attr('href');
					if(block == "#leaderboard"){
						$(block).fadeIn();
						$('#login').hide();
             $(document).find('.active').removeClass("active");
             $(this).parent().addClass( "active" );
					}
					if(block == "#login"){
						$(block).fadeIn();
						$('#leaderboard').hide();
             $(document).find('.active').removeClass("active");
             $(this).parent().addClass( "active" );
					}
				});

 $('.tab.active a').click(); // Default open
			});

看起来你只是缺少了一行默认显示第一个标签信息的代码。我把它添加到了 document.ready 后面 

$(document).ready(function() {
  $("#leaderboard").fadeIn(); //This displays the first tab info by default**       
  var _this = $('.tab a:first')
  var block = _this.attr('href');
  $('.tab a').on('click', function(e) {
    e.preventDefault();
    var _this = $(this);
    var block = _this.attr('href');
    if (block == "#leaderboard") {
      $(block).fadeIn();
      $('#login').hide();
    }
    if (block == "#login") {
      $(block).fadeIn();
      $('#leaderboard').hide();
    }
  });
});
