How to set innerhtml with selected dropdown option text using jquery or javascript?

本文关键字：选项 文本 innerhtml 设置 jquery 何使用 javascript      更新时间：2023-09-26

我想使用选定的下拉选项文本更改锚标记的内部文本

这是我的下拉列表代码，在此下拉列表中选择的任何选项，我想在另一个锚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
更新锚标签class="dropdown-open"innerhtml列出所选文本

<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了具有文本日语的选项，那么我想将锚标签 innerhtml 文本英语更改为日本人。

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>

试试这个.. :)

<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.1.min.js">     </script>
<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>
<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>
<script  type="text/javascript">
$('#shopperlanguage').change(function(){
$('.dropdown-open').text($(this).find('option:selected').text());
});
</script>

试试 javaScript

var e = document.getElementById("shopperlanguage");
var strUsertext = e.options[e.selectedIndex].text;
document.getElementsByClassName("dropdown-open")[0].childNodes[1].nodeValue = strUsertext;

演示

使用 On change Jquery with javascript 

$('#shopperlanguage').on('change', function () {
    $(".dropdown-open")[0].childNodes[1].nodeValue = this.options[this.selectedIndex].text;
}).change();

演示

我<span class="text"></span>添加到您的标记中，以便更容易选择目标区域：

$('#shopperlanguage').on('change', function() {
  $('.cat-select a span.text').text( $('option:selected',this).text() );
})
.change();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<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>
</select>
</span>
<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"> <span class="text">English</span></a>
</div>
</div>

<select name="abc" id="abc" onchange="chng()">
<option value=""></option>
<option value="English">English</option>
<option value="Japanese">Japanese</option>
</select>

<a href="#" id="atag">English</a>
<script>
function chng()
{
   var s= document.getElementById('abc').value;
   document.getElementById('atag').innerHTML = s;
}
</script>

这是工作演示。请尝试一下。
