JavaScript获取Select当前值写法：

var value = document.getElementById("select").options[document.getElementById("select").options.selectedIndex].value;

var text = document.getElementById("select").options[document.getElementById("select").options.selectedIndex].text;

例子：

复制代码 代码如下:

<script>

function check() {

var select = document.getElementById("select").options[document.getElementById("select").options.selectedIndex].value;

alert(select);

}

</script>

<select name="select" id="select">

<option value="test1" selected="selected">Test1</option>

<option value="test2">Test2</option>

</select>

<input type="button" value="我要试试"/>
