Java脚本中HTML选择控件的访问值和所选文本 [英] Access Value and selected text of html select control in java script

问题描述

我有一个这样的选择控件.

I have a select control like this.

<script type="text/javascript">
        function countrychange() {
            var cou = document.getElementById('country').value;
            alert(cou);
        }
</script>

<select id="country" name="D1"  önchange="countrychange()">
        <option value="IN">India</option>
        <option value="US">USA</option>
</select>

当我更改任何国家/地区时，它将显示我的价值，但是我想这样显示，假设选择了Option-India，那么它应该向我显示印度.

When I change any country then it is displaying me it''s value, but I want to display like this, suppose Option-India selected, then it should show me India.

推荐答案

您是否熟悉Jquery ..?
或尝试这个

are you familiar with Jquery..?
or Try this

var name=document.getElementById('country')[document.getElementById('country').nodeType].innerHTML

var sel = document.getElementById('country');
var index = sel.selectedIndex;
var text = sel.options(index).text;
alert('the text is :'+ text + '\nthe value is : '+sel.value);
