我该怎么用 list instead of dropdown for the languages switcher?

Question

我使用msDropDown将<select>转换为<ul>列表，用于语言切换器。但问题是，使用这个jQuery插件，选择页面加载后需要很长时间才能加载。

那么，我怎样才能使用ul列表而不是select？

这是我的选择代码：

<select name="lang" class="language" onchange="location.href='index.php?lang='+this.value+''.$trackpage.'">
    <option name="lang" data-image="style/lang/de.png" value="de">Deutsch</option>
    <option name="lang" data-image="style/lang/en.png" value="en" selected="selected">English</option>
    <option name="lang" data-image="style/lang/es.png" value="es">Espanol</option>
    <option name="lang" data-image="style/lang/fr.png" value="fr">Francais</option>
    <option name="lang" data-image="style/lang/it.png" value="it">Italiano</option>
</select>

我尝试过：

<ul onchange="location.href='index.php?lang='+this.value+'">
    <li>
        <a href="" name="lang" data-image="style/lang/de.png" value="de">English</a>
    </li>
</ul>

但value和onchange不支持ul和a。 有没有办法让ul与select属性一起使用？

谢谢！抱歉我的英语不好！

2015年更新答案

由于这个问题仍然经常访问，并且由于评论中的一些要求，我重新访问了我的代码。你仍然可以在下面找到我的原始答案。

HTML

<button class="language_selector">Choose Language</button>
<ul class="languages">
    <li><a href="/en">English</a></li>
    <li><a href="/de">Deutsch</a></li>
</ul>

<article>
    <h1>More Content</h1>
</article>

JavaScript的

var trigger = $('.language_selector');
var list = $('.languages');

trigger.click(function() {
    trigger.toggleClass('active');
    list.slideToggle(200);
});

// this is optional to close the list while the new page is loading
list.click(function() {
    trigger.click();
});

CSS

.language_selector {
    width: 200px;
    background: #222;
    color:  #eee;
    line-height: 25px;
    font-size: 14px;
    padding: 0 10px;
    cursor: pointer;
}

.languages {
    display: none;
    position: absolute;
    margin: 0;
    background: #dddddd;
}

.languages > li {
    width: 200px;
    background: #eee;
    line-height: 25px;
    font-size: 14px;
    padding: 0 10px;
    cursor: pointer;
}

.languages > li:hover {
    background: #aaa;
}

原始答案从2013年

我会这样做：

var nav = $('#nav');
var selection = $('.select');
var select = selection.find('li');

nav.click(function(event) {
    if (nav.hasClass('active')) {
        nav.removeClass('active');
        selection.stop().slideUp(200);
    } else {
        nav.addClass('active');
        selection.stop().slideDown(200);
    }
    event.preventDefault();
});

select.click(function(event) {
    // updated code to select the current language
    select.removeClass('active');
    $(this).addClass('active');

    alert ("location.href = 'index.php?lang=" + $(this).attr('data-value'));
});

h2 {
    width: 200px;
    background: #222;
    color:  #eee;
    line-height: 25px;
    font-size: 14px;
    padding: 0 10px;
    cursor: pointer;
}
ol.select {
    display: none;
}

ol.select > li {
    width: 200px;
    background: #eee;
    line-height: 25px;
    font-size: 14px;
    padding: 0 10px;
    cursor: pointer;
}

ol.select > li:hover {
    background: #aaa;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<h2 id="nav">Choose Language</h2>
<ol class="select">
    <li data-value="en">English</li>
    <li data-value="de">Deutsch</li>
</ol>

这个添加了一个选定元素的类。如果您在选择后留在该页面并且不使用location.href，则此方法有效。

Answer 2

您不能使用select属性，而是可以创建自己的属性并在<ul>元素中使用它们

也许这会对你有所帮助

首先是html代码

<div id="language">Change Lang</div>
<ul id="lang">
    <li>
        <a href="" name="lang" data-val="de">
           <img src="http://icons.iconarchive.com/icons/famfamfam/flag/16/ad-icon.png"/>
        English</a></li>
    <li>
        <a href="" name="lang" data-val="he">
            <img src="http://icons.iconarchive.com/icons/famfamfam/flag/16/il-icon.png"/>
            Hebrew</a></li>
</ul>

接下来是jquery代码

$("#language").click(function(){
   $("#lang li").slideToggle();
});

$("#lang li").click(function() {
    var url = location.href = "index.php?lang=" + $(this).find('a').attr("data-val");
   location.href =url;
});

我没有插件就做到了。

请注意我创建了一个data-val属性，以便存储所需的语言。我使用jquery代码获取此属性

一个非常简单的（ul选择下拉列表jquery转换）无需更改html，对移动菜单非常有用：

$(function(){
  var close = function() {
    $("ul").each(function() {
      var $thisUl = $(this);    
      if($thisUl.find("li > a.click").length == 0) {
        var $li = $(document.createElement('li')).append($(document.createElement('a')).attr({
          "class": "click selectable visible",
          "href": "#"
        }).text("Select"));
        $thisUl.append($li);
      }
      else {
        $thisUl.find("li > a.click").addClass("visible");
      }
      $thisUl.find("li:has(> a:not(.click))").hide();
      $thisUl.find("li > a.click").show();
    });
  };

  var sentinel = function() {
    $("ul").each(function(){
      var $thisUl = $(this);
      $($thisUl).find("li > a").click(function(event){
        if($(event.target).is('ul li a.visible')) {
          event.preventDefault();
          $thisUl.find("li:has(> a:not(.click))").show();
          $thisUl.find("li > a.selectable").hide();
          $thisUl.find("li > a.click").removeClass("visible");
        }
        else {
          $thisUl.find("li").each(function(){
            $(this).find("a").removeClass("click selectable visible");
            $(this).find("a.selectable").remove();
          });
          $(this).addClass("click visible");
          close();
        }
      });
    });
  };

  var reconnaissance = function() {
    $(document).click(function(event) {
      if(!$(event.target).is('ul li a')) {
        close();
      }
    });
  };

  close();
  sentinel();
  reconnaissance();
