uhh.... "congrats"?
:p
This is what recursive functions are useful for. On the other hand, that would be a great way to guarantee crashing your browser. (Did 10000000 not crash it?)
Yep, sometimes it crashed and sometimes IE stopped it because the script took to long. I'm not actually sure how many of the values it printed.
what, you didn't COUNT THEM !?!?!Quote:

Happy Traq? :D
Okay -
but know it'll only print around 25000 before IE9 says it's running for to long and stops it.Code:<html>
<head>
</head>
<body>
<div id="display"></div>
<input type="button" onclick="count()" />
<script type="text/javascript">
for(var i=0; i<100000000; i++) {
var randomNumber=Math.floor(Math.random()*100)
var getID = document.getElementById('display');
getID.innerHTML = getID.innerHTML + randomNumber + " ";
}
function count() {
var getID = document.getElementById('display');
var numNum = getID.innerHTML.split(' ').length;
alert(numNum - 1);
}
</script>
</body>
</html>
Anyone got a suggestion to make it run faster or print more values?
I'm only fiddling with this for fun so mods, please don't move this thread to a different forum.
Nope. That's the memory limit for your browser. You can close all other applications, buy more RAM, and potentially switch to a more efficient browser (not sure which is best), but in the end it'll still have a maximum amount.
Though, Daniel, correct me if I'm wrong, I think you can reduce the amount of memory used by opening up your variables. For example, something like the following:
(only defining getID once, never defining randomNumber, using appendChild and createTextNode because that way the browser doesn't need to render anything, therefore faster).Code:for(var i = 0, getID = document.getElementById('display'); i < 100000000; i++){
getID.appendChild(document.createTextNode(Math.floor(Math.random()*100) + " "));
}
@keyboard
I'm just as scared to run this as I am:
Code:while(1){
document.write(1);
}
You can optimize it, but it's still going to max out. I also expect that it will get you smaller and smaller improvements because holding all of that in memory (just the text of the page even) will eventually be too much for the computer and compound on itself.
Thanks guys :D
There is a way to do this, but it won't be as fast.
I didn't really test it, but I'm assuming that it works.Code:<script type="text/javascript">
var count = function() {
if (typeof i == "undefined") i = 0;
if (i < 1000000) {
i++;
document.getElementById("whatever").innerHTML += i;
setTimeout(function() { count(i); }, 0);
}
}
window.onload = function() {
var div = document.createElement("div");
div.id = "whatever";
document.body.appendChild(div);
count();
}
</script>
EDIT: I did test it, it works.
But that would just print out one number wouldn't it? I'm trying to print out 100000000 numbers not the number 100000000.
No check it again, I edited it slightly, it prints out however many numbers you want. It's slower, but it won't crash your browser.
And I actually figured out a way to make this even faster:
keyboard, you can mess with those two variables to figure out where the maximum performance lies.Code:<script type="text/javascript">
var count = function() {
if (typeof i == "undefined") i = 0;
var interval = 100, max = 100;
if (i < max) {
for (var a = i; a < i+interval; a++) {
document.getElementById("whatever").innerHTML += a;
}
i = i+interval;
setTimeout(function() { count(i); }, interval);
}
}
window.onload = function() {
var div = document.createElement("div");
div.id = "whatever";
document.body.appendChild(div);
count();
}
</script>
Michael, you complete legend :)
