Introduction
In this article, I will explain with the help of an example to get selected Text and Value of DropDownList on OnChange event using JavaScript.
When an item is selected in the HTML Select DropDownList, the GetSelectedTextValue JavaScript function is executed to which the reference of the HTML Select DropDownList is passed as parameter. Using this reference, the selected Value & Text is determined and is displayed using a JavaScript alert box.

<option value="3">Honda</option>
<option value="4">Audi</option>
<option value="5">Mercedes</option>
</select>
<script type="text/javascript">
function GetSelectedTextValue(ddlCars) {
var selectedText = ddlCars.options[ddlCars.selectedIndex].innerHTML;
var selectedValue = ddlCars.value;
alert("Selected Text: " + selectedText + " Value: " + selectedValue);
}
