Trying to compare cancel from prompt dialog not working

RabbitTrail

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

That break inside the if does nothing...only jumps out of the if and continues to the switch! You meant return I think...

I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V)

Just put a breakpoint and see what the value of color is.

There are only 10 types of people in the world, those who understand binary and those who don't.

prompt returns a string var to check an var take if(color!=null) ... to check the value of var take if(color!='') and so on break-statement is not a member of if-statement
