IE8: This object doesn't support this property or method on line 23 #46

Closed ralt closed 12 years ago

ralt commented 12 years ago

Just including the following in my HTML like this:

<!-- [if IE 8]>
<script src="https://raw.github.com/Raynos/DOM-shim/master/lib/DOM-shim-ie8.js"></script>
<![endif] -->
<script src="https://raw.github.com/Raynos/DOM-shim/master/lib/DOM-shim.js"></script>

Gives the following error in IE8:

This object doesn't support this property or method

IE tells me the error is on line 23:

domains.forEach(function(e){

Is forEach supported in IE8? Adding ES5-shim doesn't help since it doesn't support IE8 (well, it throws an exception, so the shim doesn't work).

<html>

<head>
<!-- [if IE 8]>
<script src="https://raw.github.com/Raynos/DOM-shim/master/lib/DOM-shim-ie8.js"></script>
<![endif] -->
<script src="https://raw.github.com/Raynos/DOM-shim/master/lib/DOM-shim.js"></script>
<script src="https://raw.github.com/kriskowal/es5-shim/master/es5-shim.js"></script>
</head>

<body>

<p id=test>test</p>
<script>
var domains = ["test"];
domains.forEach(function(e){
    alert(document.querySelector("#" + e).innerHTML)
});
</script>

Works even in IE7. WAIDW?

Well, I guess this is on my environment then.

Debugging in IE, I've found that [].forEach() returns the same error message right before the domains.forEach line.

If I put the ES5-shim script after the DOM-shim, using [].forEach() works correctly after the page has completely loaded.

If I put the ES5-shim script before the DOM-shim, I get the following error on line 23:

Exception thrown and not caught

However, using [].forEach() works once the page is loaded.

I don't get what is wrong, and I don't know how I should debug this.

I don't get it either :D

Here is a jsfiddle: http://jsfiddle.net/YhG7H/

This jsfiddle, with IE8, shows the behavior explained up there (error at line 23, etc).

I have IE8.0.6001.18702.

change the order of es5 shim and dom shim and problem solved

ralt commented 12 years ago

No, it doesn't solve the problem. But I don't have time to mess around with this for now, I'll reopen when I'll have more information.
