ie6 AND ie7?

Tom · April 26, 2007, 05:08:26 PM

Can you get both installed in some manner on XP? I need to do some testing with both, as well as firefox, and while it (the site) works fine in firefox, theres a Js error somewhere with IE7 (even thought I could swear it was all cross browser compatible).

I've heard from one person saying there is a hacked version of ie6 that can be installed alongside, but some things like conditional CSS statements are missing. I'd prefer to have it work the same as it normally would. And I don't have enough ram to run two vmware XP images simultaneously (at least not with 512MB to each, I'll try less, but It might not be enough to run xp

).

XP can run with 128MB of RAM - I know because that's all I could squeeze onto the motherboard of my Pentium 166Mhz machine. It was excuciatingly slow, but that's because it was a *very* old HDD (2.1GB). IE6 and IE7 do not live side-by-side natively. IE7 forces itself over IE6. If you have a hacked IE6 running, you have to ask yourself whether your JS is being interpreted by the IE6 or IE7 engine.

I recommend you run two boxes or two virtual machines. Since you're only testing web sites, you could easily run each image with only 256MB, or even 192MB. Now, if you were testing AutoCAD, there's no way I'd recommend you run the virtual machines with under 1.5GB each

Heh. Still, I don't like giving windows less than 512MB

Its like a rule or something. The fact that with 512MB ram set, it was using 300MB of Host ram...

Microsoft has snuck in some updates lately the stop some of the incompatibility issues, however some users of applications I support are having grief which is making it hard for them to work, to that I say...

GET FIREFOX

I guess I should make the menus work in Mozilla-based browsers for the next code release haha

Duel boot?

Tom · April 26, 2007, 08:45:51 PM

My primary development system is Linux, (I'm used to having all the tools I need

) Having to triple boot to test out every little change in the silly little ajax app would take forever and get quite annoying

Using two vmware sessions at once seems to be working ok, but IEs debugging sucks so bad its not funny.

Thorin · April 26, 2007, 08:58:56 PM

Are you using the Microsoft Script Debugger?

Yup. It's much better than the default dialog, though I can't be sure if its even reliable information at all. I get two or three errors from two things:

1. /* multi line comments */
2. <tag onfoo="foo();">

I can only assume the second error is coming from the first one, but does IE not do /* comments */ ?

I haven't been able to find any information on IEs support for that style of js comment.

Thorin · April 26, 2007, 09:12:20 PM

Sorry, I meant the Microsoft Script Editor (gotta read the page I'm linking to before posting the link

).

I don't recall IE's JScript having a problem with multi-line commenting, and in IE6 it's supposed to support all of ECMA-262. Can you provide a code snippet in context?

Tom · April 26, 2007, 09:25:06 PM

Sadly you need Office of some sort to have MSE. I don't and I'm not sure my VMs have enough disk space

But after taking a close look at the code, it SEEMS that IE just doesn't like the trailing , in:

Code Select


{
  foo: 123,
  bar: 321,
}

Not even a warning in Firefox. yet it totally kills IE?

And now my other error:

Code Select

<body onload="onLoad();"> I've also tried "return onLoad();", and "onLoad();return false;", etc. It keeps sayng "Expected identifier, string or number" for the text just after onload=" ..

Colour me confused.

edit: ok, that one too seems to have been a trailing ,...

Now I have an error in the "prototype" javascript library? yeeesh..

edit, yeah, its saying "this.initialize" isn't an object or function.. Not sure why. Seems its supposed to be a JS builtin of some form?

Mr. Analog · April 26, 2007, 10:09:29 PM

If you do this:

Code Select


<html>
<script language="JavaScript">
function foo()
{
     //TODO: ADD CODE HERE
}

function doFoo()
{
     foo();
}
</script>
<body onBar="doFoo()">

     <div>blah</div>

</body>
</html>

will work but...

Code Select


<html>
<body onBar="doFoo()">

<script language="JavaScript">
     function foo()
     {
          //TODO: ADD CODE HERE
     }

     function doFoo()
     {
          foo();
     }
     </script>

     <div>blah</div>

</body>
</html>

...won't because IE will process script calls and look for script declarations while it is parsing the content mid-stream.

Mr. Analog · April 26, 2007, 10:14:17 PM

Ahh, also;

Code Select

<body onload="onLoad();">

OnLoad is a pre-existing event handler for the MSIE document object class, try changing the name of your function call.

Look up the Document Object Model on MSDN DHTML Reference:

Tom · April 26, 2007, 11:08:05 PM

I'm confused, why would a global onLoad() call resolve to document.onLoad ?

You can override an event handler in IE be redeclaring it, but if you use the HTML adornments for event handling MSIE doesn't play nice.

Code Select

this.document.body.onload = function () { doFoo(); }

I really dislike IE

Oh well. If I cant get it to work, theres a chance I don't get payed. woo.

I have to rework the silly tabview thing I wrote a little anyhow, since its complaining about an issue with that particular class/object.
