Hello everybody. Ive wrote a simple program, more simple than what I usually do, but somehow
it doesnt work. I just want it that when you check the checkbox and click the button an alert
message appears. If a message appears only when the checkbox is checked that works too.
Thanks for reading this, and hopefully youll answer to this post.

<div id= "div">

<form id= "row" method= "POST">Dulce/Salado



<input type="checkbox" name="option3" value="International" id= 'inter'> International</input>
<input type="button" value="check" onclick="f()">
</form>
</div>

<script type= "text/javascript">

function f()
{
var inter= document.form.getElementById("inter");

if (inter.checked== true)
{
alert("Something");
}
}
</script>

Here:

<form id= "row" method= "POST">Dulce/Salado
				    
		    
					    
					    <input type="checkbox" name="option3" value="International"  id= 'inter'> International</input>
					    <input type="button" value="check" onclick="f()">
				    </form>
			    
			    <script type= "text/javascript">
						  
		    function f()
		    {

		   var inter= document.getElementById("inter");
		    if (inter.checked== true)
		    {
			 alert("Something");
		    }
		    }
</script>

Yeah, it's document.getElementById, not document.form.getElementById.

Now it works, thanks a lot. But how will this be without the button, just the checkbox. When the checkbox is checked display an alert:

<div id= "div">

<form id= "row" method= "POST">Dulce/Salado



<input type="checkbox" name="option3" value="International" id= 'inter'> International</input>

</form>
</div>

<script type= "text/javascript">

function f()
{
var inter= document.getElementById("inter");

if (inter.checked== true)
{
alert("Something");
}
}
</script>
