How to Get value of a select box in JavaScript

If you are using Id to get a select box value then it's little bit easier . If you don't have id in your select box then you need to use name attribute to select the select box. I have used name tag to get the select box value.

<script type="text/javascript">

function slectBox()

{

var aa= document.form.selectBox.selectedIndex;

var ab= document.form.selectBox.options[aa].value;

alert(ab);

}

</script>






<form action="" name="form">

<select name="selectBox">

<option value="1">one</option>

<option value="2">Two</option>

</select>

<input type="button" onclick="slectBox()" value="clickme" />

</form>




This is the example how it works.try it

one
Two
