execScript try/catch oddity in IE 8
<p>I am using execScript within a try/catch  block to execute a piece of stringified JavaScript. If the string has a javascript error within execScript will return the following error within the catch block in IE 8 on a subsequent reload of the page:</p>

<p>'Error: Could not complete the operation due to error 80020101.'</p>

<p>Are there any other ways of globally evaluating javascript in IE 8 which will not throw a generic error like the one above. I know that using eval will not work since it does not evaluate the javascript in the global context.</p>

<p>Below is some setup as to what my code looks like, fn is the string that is to be evaluated:</p>

<pre><code>// fn is defined somewhere above this code

function globalEvaluation() {
    if(document.defaultView) {
       document.defaultView.eval.call(undefined, fn);
    } else if (document.parentWindow) {
        document.parentWindow.execScript(fn);
    } 
}

return function() {
    try {
         globalEvaluation();
    } catch(e) {
       // do some error handling
       // in IE 8 I get the 80020101 error
   }
}
</code></pre>
