Question

我的应用程序主页上有一些导航标签。其中一个标签有下拉列表。单击任何选项卡时，我希望内容加载在页眉和页脚之间的同一页面上。所有文件都是内部文件。我怎样才能实现这一点，最好使用AJAX JQuery？此外，我想选择其内容已加载的特定选项卡。我的代码片段：

$(document).ready(function() {

  $(".dropdown").mouseenter(function() {
    $("#myDropdown").show();
  });

  $("#myDropdown, .dropdown").mouseleave(function() {
    $("#myDropdown").hide();
  });
});

/* This is the stylesheet of the main page index.html. */

#header {
  display: block;
  width: 100%;
  height: 10em;
  margin: 1px 20px 2px 1px;
  border-bottom: 3px red solid;
  background: url("images/body-bg.jpg") -20px repeat-y, url("images/gold.gif") 220px 10px no-repeat, url("images/back.png") 320px 10px no-repeat, url("images/AR.png") 480px 10px no-repeat, url("images/black-horizntal.png");
  background-size: auto, 100px, 150px, 120px, auto;
}
#title {
  text-align: center;
  color: white;
  font-weight: bold;
  font-family: "Arial", Georgia, serif;
  font-size: medium;
  padding-top: 46px;
}
#tabs {
  float: left;
  width: 100%;
  background: none;
  /* border-bottom:4px solid #000; */
  overflow: hidden;
  position: fixed;
}
#tabs ul {
  clear: left;
  float: left;
  list-style: none;
  margin: 0;
  padding: 0;
  position: relative;
  left: 50%;
  text-align: center;
}
#tabs ul li {

  float: left;
  list-style: none;
  margin: 0;
  padding: 0;
  position: relative;
  right: 50%;

/* CSS for dropdowns of the "Matrix" tab */

#myDropdown {
  display: none;
}
body {
  overflow: auto;
  height: auto;
  width: 100%;
}

它可能看起来像这样：

$(".dropdown-content a").click(function(e){
    /* stop the a tag from going to the page */
    e.preventDefault();
    var url = $(this).attr("href");
    $.ajax({
        url: url,
        type: "post",
        success: function(data) {
            /*selector will be the area you want to load the data*/
            $(selector).html(data);
        }
    });
});
