Thank you. I works fine.

Thank you for pointing out my mistakes. I modified my code to include your corrections but the focus still does not put the cursor in the blank text or textarea continters. Any other suggestions? I have tried the code in IE, Firefox and Chrome.

Below is code I have been trying. Everything works except the focus. When the alert box's OK is clicked, focus is not set to the blank text/textarea control that caused the error to happen. According to articles online, this should work but it is not. Any suggestions would be greatly appreciated.

Trying It Out
function checkForm()
{
var str = ''; //for testing purposes later
var e = document.getElementById('myForm').elements;

   //Insert for statement here//
	for(i=0; i <= e; i++){
		if(e\[i\].value.length <1){
			alert("The field " + e.\[i\].name + " is blank");
			var mytext = document.getElementById(e\[i\].name)
			mytext.focus();
			return false;
			
		}
	}

 }

Below I have the code I am working with. The if statement in the script is not working. What I want to do is catch the value of the prompt dialog box if the user clicks the cancel buttom and exit the script if that is the case. I have tried: if (color=="null") if (color==="null") if (color=='null') if (color==='null') if (color==null) if (color===null) and none of them work. I can make the script work if I do: if(color!=null) and modify the logical processing but I am trying to make work with the equals comparison. If I comment out the if conditional statement, it works fine. Any help is greatly appreciated. Thank you.

<!--
var color = prompt("Enter a color","Enter red, white, or blue.")

function colorTest(){

    //\*\*\*\*\*\*\*\*\*\* if statement not working properly
if(color === null){
	break;
}

switch(color){
case "red":
	alert("You have entered the color ' red '");
	break;
case "white":
	alert("You have entered the color ' white '");
	break;
case("blue"):
	alert("You have entered the color ' blue '");
	break;
default:
	alert("You did not enter a valid color");
	
}

}//end function

I have been trying to get the method to work. I have seen and tried quite a few online examples including the example found on W3C (which is below). Even on their site, it doesn't work. I have tried to get the method to work by: Refresh the page, using back and forward buttons, and closing the window. Nothing happens in IE, Firefox or Chrome. I am at a loss as to why this doesn't work.

<html>
<head>
<script>
function myFunction()
{
alert("Thank you for visiting W3Schools!");
}
</script>
</head>
