Today, I ran some tests to help me understand the scope in which an eval runs. Turns out, like so many things in the browser world, it's very unpredictable and exhibit different behaviors in different browsers.
Let's start with the following snippet of code. I've added comments to demarcate areas in the code, which I will be changing with each iteration.
var foo = 123;
var bar = {
changeFoo: function() {
// We'll keep changing the following snippet
alert(this);
eval("var foo = 456");
// Changing snippet ends
}
};
bar.changeFoo();
alert(foo);
A little explanation of the code above. foo
is a variable in the global scope, and it's value is set to 123. An object bar
is created with a single method changeFoo
which does an eval
. The eval
creates a local variable (thanks to the var
) foo
, and sets it's value to 456. bar.changeFoo
is called, and the value of the global foo
is alert
ed.
The aim is to test the scope in which eval
runs. If eval
is in the global scope, the global variable foo
should change it's value. If eval
is in the local scope, the global foo
should be unaffected. Then there are various things we can do inside the changeFoo
method which should keep altering the scope of this
, so we are also alerting this
to see what happens.
The findings are listed below:
Changed snippet | Internet Explorer | Safari 3.x | Firefox | Google Chrome | Safari Nightlies | ||||||
---|---|---|---|---|---|---|---|---|---|---|---|
foo | this | foo | this | foo | this | foo | this | foo | this | ||
1 |
| 123 | object | 123 | object | 123 | object | 123 | object | 123 | object |
2 |
| 123 | object | 123 | object | 456 | object | 123 | object | 456 | object |
3 |
| error | object | error | object | error | object | error | object | error | object |
4 |
| 123 | object | 123 | object | 456 | object | 123 | object | 123 | object |
5 |
| 123 | object | 123 | window | 123 | window | 123 | object | 123 | window |
6 |
| 123 | object | 123 | window | 456 | window | 123 | object | 456 | window |
7 |
| 456 | object | 456 | object | 456 | object | 456 | object | 456 | object |
8 |
| 456 | object | 456 | object | 456 | object | 456 | object | 456 | object |
What I think of these results:
- I don't know what Firefox is doing in case 2, and for some reason Safari Nightlies seem to be following it. Maybe it's just beyond my understanding, but case 2 is not supposed to be different from case 1. Why does case 2 operate in global scope? If
window.eval
is different fromeval
, case 3 shouldn't all have given errors. Someone please help me understand that $hit. - Case 4 makes sense, but that's a non-standard behavior in Firefox. Understandable that no one else exhibits it.
- IE baffles me in case 5, and Chrome seems to ape it. In this scenario, the anonymous function is supposed to have the global scope - so, in this case,
this
should point to the window. WTF is happening here! - Consistent with case 2 above, Firefox and Safari Nightlies continue to display weird behavior in case 6. For some reason, in these two cases, the
eval
operates in the global scope. - Now, I have no idea why, but only cases 8 and 9 seem to really work at all. This is despite Doug Crockford going on and on about not using
with
constructs. It's also despite being beyond (my) understanding about why thewith
should make any difference to theeval
, sinceeval
is part of the window object.
All in all, if you are going to be eval
ing JavaScript (not JSON), and you want the eval'd code to run in the global scope, you should use the with
block around the JavaScript snippet. Or else, you can lose a lot of hair handling cross-browser issues.
Hope you don't lose as much hair as me.

1 – 200 of 204 Newer› Newest»Thanks for sharing your findings. However for me in Firefox 3 variation 7 and 8 only work as expected if foo exists in global scope at the time the string is eval'd. Otherwise it will just put foo into local scope.
Can anybody confirm this behavior?
IE is handling case 5 more like I'd think. I couldn't find the docs on anonymous function scope and ownership so I can't say if its correct, but I'd think it would be part of its containing scope, like a method.
Interesting... I was looking for a way to run eval in global scope from within objects, but didn't think of using 'with'. Nice to know it's possible after all.
As for case 2... it seems that in FF's case, window.eval isn't the same as eval. (window.eval !== eval)
And eval isn't a standard method on objects (anymore?), which explains 3 vs 2.
Another case you could've tested is eval.call or eval.apply
they turn out the same as window.eval though.
And as an oddity, FF doesn't allow eval.call(this, ...) (same with apply).
(I don't have Safari nightly though, so can't account for any of this there)
I use
with (this) {
// some code
this.doSomething();
}
it seems to work - usually anyway
Firefox 3 and Safari nightlies both follow the ES4 semantics for eval, that is "eval" on its own acts in the scope it is used within, whereas globalObject.eval acts in the global scope.
Neither allows aliases to eval anymore.
anonymous1: You might be right. Will get back to you.
xero: A bug in JavaScript ensures that private functions run on the global scope, even if they have access to the constructor's variables through a closure. It's not what you'd expect, but that the way the language is.
rael: I don't think eval was ever supposed to be a standard method on objects. In fact, now that I think of it, case 3 proves nothing really.
anonymous2: From everything I know, you are not achieving anything by enclosing your code in the with statement.
oliver: You indeed seem right, going by my observations. It doesn't help in today's world, but maybe it's the right thing for the future.
If foo isn't declared in the global scope all your tests will (should) only set it in the local scope. Thus the final alert(foo) will throw.
If you want to execute some script in the global scope you should use dynamic script insertion.
If you want to evaluate some code outside of the local scope - so that local variables don't bleed in - then call eval indirectly via another function. e.g.
function evalScript() {
return eval(arguments[0]);
}
Good one. :)
i think that a timeout runs in global scope, and wrapping its contents in a "quotes" means that it will run the code as an eval.
obviously this has its downsides that it will run at the end of your current running block of code, not at the exact time that it is set (eve if a time of 0 is specified) but it will defiantly in all browsers run in the global scope (and may fix any problem you were looking to solve)

There is also a difference between
eval("var foo = 456");
and
eval("foo = 456");
Found a related Ajaxian post from a year ago: http://ajaxian.com/archives/evaling-with-ies-windowexecscript
This is the best way to solve the eval problem:
if (window.execScript) window.execScript(sCode); //ie
else top.eval(sCode); //others
Jery
For a more generalized solution with tests take a look at:
http://caih.org/open-source-software/loading-javascript-execscript-and-testing/
I don't have the browsers on hand to test this, but is the immediate calling environment accessible to eval?
Example, should return 10:
function foo() {
var bar = 2;
eval("bar = 10");
return bar;
}
I'm wondering if some quirky browsers might place eval in an isolated environment (or to some random degree). Thank you for the work you've done so far.
Tomorrow I will run a test too. I will show you my results... the information that you have here its very important...
thank you
Beth T. Cormier
This is a very interesting topic ,if possible id like to know if you could provide me with a little more data on this.
I've been using this version for years. It works everywhere.
The magic is in the intermediate variable realGlobal.
function globalEval(src) {
var realGlobal = this;
if (window.execScript) // eval in global scope for IE
window.execScript(src);
else // other browsers
realGlobal.eval(src);
}
This also works, and is even simpler:
function globalEval(src) {
if (window.execScript) // eval in global scope for IE
window.execScript(src);
else // other browsers
eval.call(null, src);
}
If the eval is really happening in the global scope, then not only would "var foo=456" modify outer foo, but you could also declare a new global var visible after the eval completes. Change the snippet to:
"var foo=456, baz=789"
and the post-eval alert to:
alert(foo+","+baz);
and you'll find that the ONLY way to do a global eval in IE7 (when this artical was written) is to use window.execScript.

What an insightful and thorough exploration of the scope in which an eval runs! It's fascinating to see how different browsers handle the same code differently. Your findings testify to the importance of being mindful of the scope when using eval, especially when dealing with cross-browser compatibility.

Astonishing read! Navigating through browser unpredictability is a constant challenge, isn't it? Your testing reminds me of a project I worked on where we tried to decode the mysteries of 'eval' scope across different browsers too. We reached a similar conclusion - it's undeniably inconsistent! Lost a fair share of hair, indeed! I agree, it's baffling how the 'with' construct seems to work best in ensuring the code runs in the global scope. Keep exploring and thanks for sharing your findings!
Wow, this blog post took me on a rollercoaster of emotions! Reading about the unpredictable behavior of eval in different browsers left me scratching my head. Case 2 and Safari Nightlies really threw me off - why does global scope come into play there? The anonymous function in case 5 and its effect on "this" left me saying, "WTF is happening here!" But in the end, it seems that using the with block in cases 8 and 9 is the way to go. Kudos to the author for tackling cross-browser issues, even if it means risking some hair loss!

The behavior of eval can be highly browser-dependent, and it's important to avoid using it in ways that can lead to confusion or unexpected results. The use of the with statement, as seen in cases 7 and 8, is discouraged in modern JavaScript because it can make code harder to understand and maintain. loveland
