如何只有活动标签的背景颜色设置

时间：2016-07-06 02:54:40

标签： jquery html css ajax

我试图让AJAX标签正常工作。当前代码的问题是它没有为活动选项卡设置样式。

可能我需要用一些javascript代码解决这个问题但不知道从哪里开始。

每次id都不需要点击。我已经简化了您的代码并在点击时添加了.active。希望它有所帮助。

＆＃13;
＆＃13; 
     $("h2").addClass("white");
     $(document).ready(function() {
       // load index page when the page loads
       
       var data = {
         '#tabs-1':'Testing 1',
         '#tabs-2':'Testing 2',
         '#tabs-3':'Testing 3',
         '#tabs-4':'Testing 4',
         '#tabs-5':'Testing 5'
       };
       
       $("#response").html("DEFAULT");
       
       $('.tab').click(function(){
         $('.tab').removeClass('active'); //remove .active from all
         $(this).addClass('active'); //add .active to current pressed
         href = $(this).attr('href');
         $("#response").html(data[href]);
       });

     });

检查此代码可能有帮助

在点击功能中使用addClass() 

 $("li").click(function(){
  $(this).addClass("active").siblings().removeClass('active');

  })
 $("#page1").click(function () {
 // load home page on click
 $("#response").html("<h2> Welcome </h2><p>Sed porttitor lectus nibh. Cras ultricies ligula sed magna dictum porta. Praesent sapien massa, convallis a pellentesque nec, egestas non nisi. <br/> Curabitur arcu erat, accumsan id imperdiet et, porttitor at sem. Nulla quis lorem ut libero malesuada feugiat. Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>");
$("h2").addClass("white");
        });

＆＃13;
＆＃13; 
$(document).ready(function () {
