下拉框设置

Question

这个问题与我之前的一篇文章有关，当单击某个开关时，更改href-tag的URL。Link

我现在设置了一些不同的东西，因为我哪里也去不了。href更改现在起作用了，但我无法在下拉框中显示选定的图标和名称。

JSFiddle

因此，例如，如果选择了“德国”，那么它应该与相应的旗帜图标一起显示，作为下拉框中的当前选择。

是我的设置错误，还是需要什么才能解决这个问题？

 <div id="language-selection"><div id="current-language"><span class="element-invisible">Current language:</span>
      <img class="language-icon" src="http://www.euromonitor.com/medialibrary/Image/Flag_20x20_United_Kingdom.png" alt="English" title="English" /> English
  </div>
  <div class="element-invisible">Switch to:</div>
  <ul id="other-languages">
  <li class="zh-hans first"><a  href="javascript:;"  data-lang="Chinese" class="clickButton"><img class="language-icon" src="http://www.euromonitor.com/medialibrary/Image/Flag_20x20_China.png" alt="简体中文" title="简体中文" /> 简体中文</a></li>
  <li class="en"><a  href="javascript:;"  data-lang="English" class="clickButton" </a> <span class="language-link"><img class="language-icon" src="http://www.euromonitor.com/medialibrary/Image/Flag_20x20_United_Kingdom.png" alt="English" title="English" />English</span></li>
  <li class="de last"><a href="javascript:;"  data-lang="German" class="clickButton"><img class="language-icon" src="http://www.euromonitor.com/medialibrary/Image/Flag_20x20_Germany.png" alt="German" title="German" /> German</a></li>
</ul>
 </div>   

<ul>
    <li><a class="clickButton" href="folder1/firstLink/Languages/English/folder/index.html">Index Link</a></li>
    <li><a class="clickButton" href="../folder2/secondLink/Languages/English/folder/index.html">A different Link </a></li>
    <li><a class="clickButton" href="../../folder3/Languages/English/folder/index.html">Another different link</a></li>
<ul>

Answer 1

请将下面给出的代码添加到current = lang;之前的jquery脚本代码中

   /*Replace language flag src , alt and title*/
   $('#language-selection > #current-language > img').attr('src' , $(this).find('img').attr("src"));

   $('#language-selection > #current-language > img').attr('alt' , lang);
   $('#language-selection > #current-language > img').attr('title' , lang);

   /*check for all content in div having id current-language and check if nodeType == 3 mean string text then replace old text with new one */  
   $("#language-selection > #current-language").contents().each(function() {
         if(this.nodeType == 3)
             this.nodeValue = this.nodeValue.replace(current, lang);
     });

嗨，我对你的代码做了一点修改，以便能正常工作。您需要在选择单击时同时更改语言文本和语言图像。

HTML部件：

<div id="language-selection"><div id="current-language"><span class="element-invisible">Current language:</span>
      <img class="language-icon" src="http://www.euromonitor.com/medialibrary/Image/Flag_20x20_United_Kingdom.png" alt="English" title="English" /><span class="text">English</span>
  </div>
  <div class="element-invisible">Switch to:</div>
  <ul id="other-languages">
  <li class="zh-hans first"><a  href="javascript:;"  data-lang="Chinese" class="clickButton"><img class="language-icon" src="http://www.euromonitor.com/medialibrary/Image/Flag_20x20_China.png" alt="简体中文" title="简体中文" /> 简体中文</a></li>
  <li class="en"><a  href="javascript:;"  data-lang="English" class="clickButton"><img class="language-icon" src="http://www.euromonitor.com/medialibrary/Image/Flag_20x20_United_Kingdom.png" alt="English" title="English" />English</a></li>
  <li class="de last"><a href="javascript:;"  data-lang="German" class="clickButton"><img class="language-icon" src="http://www.euromonitor.com/medialibrary/Image/Flag_20x20_Germany.png" alt="German" title="German" /> German</a></li>
</ul>
 </div>   
...

JS在此部分中：

 ...
 var current = "English"
$("[data-lang]").on("click", function() {
    var lang = $(this).data("lang");

$(".clickButton").prop("href", function(i, href) {
        return href.replace(current, lang);
    });

    $("#current-language img").attr("src", $(this).children("img").attr("src")); // NEW 

    $("#current-language .text").text(lang); // NEW

    current = lang;
});
