copied!<blockquote> <p>if I take the guts of the render() function out (i.e., just put them after load() in main.js), this works fine.</p> </blockquote> <p>Doesn't for me in IE8. If I lose the AJAX call completely and just call <code>render()</code> in main.js, I get the same result. In fact even if I replace the whole of main.js with just:</p> <pre><code>document.write('hello!'); </code></pre> <p>with or without opening the document, the hello never appears!</p> <p>If I put any timeout (even 0) on the call to <code>render</code> in main.js, it works. The timeout on the parent document, on the other hand, doesn't seem to be doing anything.</p> <p>This extreme weirdness is caused by jQuery using a temporarily-inserted <code><script></code> tag to execute the code returned by in jsonp.js. If you simply call <code>eval</code> on the return value instead of having jQuery execute it, it works fine.</p> <p>A related problem I found narrowing down the hello example is demonstrated by index.html:</p> <pre><code><body> <iframe name="foo"></iframe> <script> var idoc= frames['foo'].document; idoc.open(); idoc.write('<body><script src="main.js"><\/script>'); idoc.close(); </script> </code></pre> <p>with main.js containing:</p> <pre><code>document.write('foo'); </code></pre> <p>There is no foo written. (An inline script, on the other hand, was fine.)</p> <p>If the <code>idoc.close</code> was omitted, it worked. If an additional <code>idoc.write('bar')</code> was added, the <code>bar</code> was written before <code>foo</code> in IE only. If I added both <code>bar</code> and the <code>close</code> call, IE crashed.</p> <p>So to summarise, there are <strong>deep problems</strong> using <code>document.write</code> from inside a document that was itself written by <code>document.write</code>! Try to avoid it if at all possible. <code>document.open</code> can be a useful way to populate an iframe from a parent document, but you shouldn't really be needing it inside the child document, where you can use DOM methods on yourself.</p>
