javascript - 如何使用jquery或javascript设置innerhtml与选定的下拉选项文本？

Question

我想使用选定的下拉选项文本更改 anchor 标记的内部文本

这是我的下拉列表代码，无论在此下拉列表中选择什么选项，我都想在另一个 anchor 标记中更新该选项的文本

<span style="white-space: nowrap;" class="" id="shopperlanguage_fs">
<select class="input" id="shopperlanguage" name="shopperlanguage">
<option value="ja_JP" class="japImg">japanees</option>
<option selected="" value="en" class="engImg">English (International)</option>/* whatever option is selected like this i want to get this text  */
</select>
</span>

我想用上面提到的下拉菜单更新 anchor 标记 class="dropdown-open"insidehtml
列出选定的文本

<div class="top-lang clearfix">
<div class="cat-select">
<a href="#" data-dropdown="#dropdown-2" class="dropdown-open"><img src="/site/images 
/lang_05.jpg"> English</a>    /* this is the anchor tag which innerhtml i want to change with selected dropdown option text */
</div>
</div>

假设如果在下拉列表中选择的选项包含文本 japanees，那么我想将 anchor 标记 insidehtml 文本英语更改为 japanees。

这是我尝试过的代码，但它不起作用

<script  type="text/javascript">
var e = document.getElementById("shopperlanguage"); 
var strUsertext = e.options[e.selectedIndex].text;
var langValue =$(".dropdown-open").text()
langValue.innerHTML= strUsertext;
</script>
