如何在IE中设置HTML的innerHTML下拉列表 [英] how to set the innerHTML of HTML drop down list in IE

问题描述

我有一个html下拉列表和按钮.

I have one html drop down list and button.

 <select style="width:170px" id="ddl"></select>
  <input type="button" value="getvalue" onclick="abc()" />

当我单击此按钮时，我需要更改下拉列表的innerHTML.为此，我正在调用一个JavaScript函数.它可用于除IE之外的所有其他浏览器.我正在使用IE8版本.所以我不知道它是否可以在其他IE版本上使用

when i click this button , i need to change the innerHTML of drop down list.for that, i am calling one javascript fuction. it is working all other browser except IE. i am using IE8 version.so i don't know whether it will works on other IE versions

  <script type="text/javascript">
    function abc()
    {
        var a = "<option selected='selected'   value='TN_Pulling'>TN_Pulling</option>";
        document.getElementById('ddl').innerHTML = a;
    }
</script>

请帮我解决一下.我错过了什么吗?

please help me to sort it out. did i missed anything ?

推荐答案

您的代码在我的IE11上有效，但在我的IE8上却无效.

Your code worked on my IE11, but not on my IE8.

这适用于我的IE8:

<script type="text/javascript">
function abc()
{
    document.getElementById('ddl').innerHTML = ''; // clear <select> contents
    var a = document.createElement('option');      // create an <option> elem
    a.setAttribute('value', 'TN_Pulling');         // set 'value' attr val
    a.setAttribute('selected', 'selected');        // set 'selected' attr val
    a.innerHTML = 'TN_Pulling';                    // set <option> contents
    document.getElementById('ddl').appendChild(a); // append <option> to <select>
}
</script>
<select style="width:170px" id="ddl"></select>
<input type="button" value="getvalue" onclick="abc()" />

祝你好运.
