Javascript execute once

Question

How do i get a javascript code to only execute or be used once? example is

var stringToMatch = 'christopher';
function toggle (){   

 var input = document.getElementById('text').value; 

 if (input == stringToMatch){  
    document.getElementById('divColor1').style.display = 'block';   
}   
else {   
   document.getElementById('divColor1').style.display = 'none';   
}   
}

this code or stringToMatch i want to execute once, after that i dont care if it is deleted in the sense. for this is for coupons. and i am making multiples of this, so once someone has typed this i want it to delete

let me better phrase now that i see adding two of these only makes the second one work. i want to make we will say 100 coupon codes. 'christopher' being the example used here. once someone hits redeem it takes 'christopher' out of the coupons list. and the others are still there. is this possible? — nextlevelgamingCO

If I got you right, you could overwrite toggle() with an empty function.

if (input == stringToMatch){  
    document.getElementById('divColor1').style.display = 'block';   
    window.toggle = function() { };
}

i dont understand this sorry. I also tried a switch a switch (stringToMatch) { case 0: x="Today it's Sunday"; break; case 1: x="Today it's Monday"; break; case 2: x="Today it's Tuesday"; break; case 3: x="Today it's Wednesday"; break; case 4: x="Today it's Thursday"; break; case 5: x="Today it's Friday"; break; case 6: x="Today it's Saturday"; break; to try and change the coupon "name" to more than just one. which it did not work. basically I want once 'christopher' is used its deleted. then if any of the others used they
