i am trying to enter a number in the textbox and show the message as name of the day in another div tag via switch function. the variable i am passing into switch function has to get the value from the textbox. but i am not able to output the function on clicking button, it shows the message “undefined”.
Help please :). Thank you

<input type = "text" id = "test" />

<div id="box3" style = "border:solid 2px blue; height:15px;width:100px;"></div>
<br>
<input type = "button" onClick = "myTest()" value = "Click me" />

<script type="text/javascript">
function myTest(){
var x;
var d =document.getElementById('test').value;
switch (d)
{
case 0:
x="Today it's Sunday";
break;
case 1:

you need to cast it to an integer first:

var d = parseInt(document.getElementById('test').value);
