Javascript Boolean Code

Question

I wrote this to switch between two states so when I click on something it will trigger this

var toggle=true;

if(toggle == true){
    alert('Toggle is on');
    toggle = false;
}
else{ 
    alert('Toggle is off');
    toggle = true;
}

It keeps alerting Toggle is on. Is there anyway I can actually 'toggle' between those two? Are there simpler ways? I am using this on a internet webpage.

When your var toggle=true; is inside your click event, your variable will be resetted on every click. So place the variable outside click function. — nkmol

Simpler and more elegant:

var toggle = true;
alert(toggle ? "Toggle is on":"Toggle is off")
toggle = !toggle

this is probably because you put var toggle=true; inside the function and not before the function declaration, show us the entire function so we know what you're talking about

Make sure the var toggle=true is outside the function containing the if(...) code. Otherwise toggle will keep getting initialized to true.
