如何在ul下拉菜單中顯示所選菜單項

Question

我有一個下拉菜單，顯示用戶選擇的字體顏色。 此時，下拉列表顯示“樣式”，但我希望菜單標題顯示當前選定的值。 這是代碼：

HTML：

<div id="font_dropdown" class="dropdown">
    <nav id="primary_nav_wrap">
    <ul>
      <li class="current-menu-item"><a>
      <li><a href="#">Style</a>
        <ul class="font-names">
          <li style="font-family: Raleway"><a>Raleway</a></li>
          <li style="font-family: palatino"><a>Palatino</a></li>
          <li style="font-family: impact"><a>Impact</a></li>
          <li style="font-family: courier"><a>Courier</a></li>
          <li style="font-family: Copperplate"><a>Copperplate</a></li>
          <li style="font-family: Monospace"><a>Monospace</a></li>
          <li style="font-family: Fantasy"><a>Fantasy</a></li>
          <li style="font-family: Calibri"><a>Calibri</a></li>
          <li style="font-family: Cursive"><a>Cursive</a></li>
          <li style="font-family: Futura"><a>Futura</a></li>
          <li style="font-family: Rockwell"><a>Rockwell</a></li>
          <li style="font-family: Andale Mono"><a>Andale</a></li>
        </ul>
      </li>
    </ul>
    </nav>
  </div>

CSS：

#primary_nav_wrap
{
  margin-top:15px;
  font-family:raleway;


}

#primary_nav_wrap ul
{
  list-style:none;
  position:relative;
  float:left;
  margin:0;
  padding:0;
  font-family:raleway;

}

#primary_nav_wrap ul a
{
  display:block;
  text-decoration:none;
  font-weight:700;
  font-size:12px;
  line-height:32px;
  padding:0 15px;
  z-index:100;



}

#primary_nav_wrap ul li
{
  position:relative;
  float:left;
  margin:0px;
  padding:0;
  z-index:100;

}

#primary_nav_wrap ul li.current-menu-item
{
  background:#ddd;
  color: orange;
  z-index:100;

}

#primary_nav_wrap ul li:hover
{
  background:#F3F4F5;
  cursor: pointer;
  color: orange;
  z-index:100;
}

#primary_nav_wrap ul ul
{
  display:none;
  position:absolute;
  top:100%;
  left:0;
  background:#fff;
  padding:0;
  z-index:100;

}

#primary_nav_wrap ul ul li
{
  float:none;
  z-index:100;
  width:235px
}

#primary_nav_wrap ul ul a
{
  line-height:120%;
  padding:10px 10px;
  text-align: left;
  left: 100px;
  z-index:100;
}

#primary_nav_wrap ul ul ul
{
  top:0;
  z-index:100;
  left:100%
}

#primary_nav_wrap ul li:hover > ul
{
  display:list-item;
  color: orange;
  z-index:100;

使用Javascript：

  $(document).on("click", '.font-names li a',  function() {    
      $("#imagewrap h3").css("font-family", $(this).parent().css("font-family"));
      $("#new_tile_font_style").val($(this).parent().css("font-family"));
   });

對不起凌亂的代碼，我對此比較陌生。 謝謝！

Answer 1

這里有一些使用jQuery執行此操作的代碼：

$(".font-names > li").click(function() {
   $("#menutitle").text($(this).text()); 
});

您還需要在菜單標題元素中添加id 。

現場演示：

 $(".font-names > li").click(function() { $("#menutitle").text($(this).text()); }); 

 #primary_nav_wrap { margin-top:15px; font-family:raleway; } #primary_nav_wrap ul { list-style:none; position:relative; float:left; margin:0; padding:0; font-family:raleway; } #primary_nav_wrap ul a { display:block; text-decoration:none; font-weight:700; font-size:12px; line-height:32px; padding:0 15px; z-index:100; } #primary_nav_wrap ul li { position:relative; float:left; margin:0px; padding:0; z-index:100; } #primary_nav_wrap ul li.current-menu-item { background:#ddd; color: orange; z-index:100; } #primary_nav_wrap ul li:hover { background:#F3F4F5; cursor: pointer; color: orange; z-index:100; } #primary_nav_wrap ul ul { display:none; position:absolute; top:100%; left:0; background:#fff; padding:0; z-index:100; } #primary_nav_wrap ul ul li { float:none; z-index:100; width:235px } #primary_nav_wrap ul ul a { line-height:120%; padding:10px 10px; text-align: left; left: 100px; z-index:100; } #primary_nav_wrap ul ul ul { top:0; z-index:100; left:100% } #primary_nav_wrap ul li:hover > ul { display:list-item; color: orange; z-index:100; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="font_dropdown" class="dropdown"> <nav id="primary_nav_wrap"> <ul> <li class="current-menu-item"><a> <li><a id="menutitle" href="#">Style</a> <ul class="font-names"> <li style="font-family: Raleway"><a>Raleway</a></li> <li style="font-family: palatino"><a>Palatino</a></li> <li style="font-family: impact"><a>Impact</a></li> <li style="font-family: courier"><a>Courier</a></li> <li style="font-family: Copperplate"><a>Copperplate</a></li> <li style="font-family: Monospace"><a>Monospace</a></li> <li style="font-family: Fantasy"><a>Fantasy</a></li> <li style="font-family: Calibri"><a>Calibri</a></li> <li style="font-family: Cursive"><a>Cursive</a></li> <li style="font-family: Futura"><a>Futura</a></li> <li style="font-family: Rockwell"><a>Rockwell</a></li> <li style="font-family: Andale Mono"><a>Andale</a></li> </ul> </li> </ul> </nav> </div>

Answer 2

也許如果你將類current-menu-item到你想要選擇的ul？

Answer 3

綁定一個click事件處理程序到你的li項目和更換的文字li 。

$('.font-names li').on('click', function () {
    var $currentMenuItem = $('.current-menu-item a'),
        currentText = $('a', this).text();

    $currentMenuItem.text(currentText);
});

但看起來你的HTML有點格格不入

 <ul>
      <li class="current-menu-item"><a>   <----
      <li><a href="#">Style</a>           <----
        <ul class="font-names">

必須根據它更改右選擇器。
