I am trying to show the prompt everytime, the user gives a null or incorrect input. Only upon, giving the correct entry, will the prompt go and an alert will be shown. This is my code:
var pass=prompt("Please enter the password to view your recovery code.");
while(true){
if(pass=="abc"){
break;
}
else
var pass=prompt("Please enter the password to view your recovery code.");
}
alert("correct");
Now, even if I give the correct value (abc), the prompt still remains and the alert never shows. Why?
It can be simpler than that. Add the prompt inside the loop, and break if the password is a match.
while (true) {
const pass = prompt('Please enter the password to view your recovery code.');
if (pass === 'abc') {
console.log('Correct!');
break;
}
}The error was because you had re-define the variable pass with the line var pass=prompt(...)
You should also consider using let instead of var
Also, i've updated the condition do make something a little bit cleaner
let pass = prompt("Please enter the password to view your recovery code.");
while(pass !== "abc"){
pass = prompt("Please enter the password to view your recovery code.");
}
alert("correct");
