My apologies for the n00b question, I've tried looking through infinite loop related issues but they're way more complex:
var replay = 1;
while (replay = 1) {
replay = prompt("Yes(1) or No(0) ?");
}
How come this is an infinite loop?
I thought this while loop would only continue iterating while the replay variable has a value of 1.
However it doesn't stop even when user input is 0, or anything else for that matter.
Thanks in advance for any of your input!
You're doing an assignment instead of a comparison.
Change:
while (replay = 1) { // Will always have a value of 1
to:
while (replay == 1) { // Will have a value of true or false
Use == instead of = in the while part.
You are assigning not checking in (replay = 1)
You need double equal signs ==, or better yet triple equal signs === which will also check the equality in types of the operands.
Besides, your code can be changed to this (preview: http://jsfiddle.net/nabil_kadimi/RfdA5/):
var replay;
while ((replay = window.prompt("Yes(1) or No(0) ?")) === '1') {
/* player wants to replay */;
}
Or even better (preview: http://jsfiddle.net/nabil_kadimi/pdV4M/):
var replay;
while (replay = window.confirm("Replay?")) {
/* player wants to replay */;
}
You need to use == (equality) instead of = (assignment) in your while loop
while(replay == 1) {
//code
}
JavaScript is doing what it is supposed to. You are reassigning the value of 1 to replay every time the loop iterates. You really want to check if replay is equal to one before proceeding.
You want to use the === comparison operator instead of the = assignment operator in the while loop.
Also, since prompt returns a string, you should compare against a string:
var replay = "1";
while (replay === "1") {
replay = prompt("Yes(1) or No(0) ?");
}
