JavaScript: (Why IE Sucks)

**Travis G** · Jan 26th, 2004, 09:16 AM

Consider the following code:

Code:

<html>
  <head>
    <title>Foo</title>
  </head>
  <body>
    <select id="mySelect">
    </select>
    <script type="text/javascript">
      myNewOption = document.createElement("option");
      myNewOption.text = "foo";
      myNewOption.value = 1;
      document.getElementById("mySelect").add(myNewOption);
    </script>
  </body>
</html>

The following works in IE 6 on Windows 2000, but not in Mozilla 1.4 on Windows XP. Mozilla's complaint is that an arguement is missing from .add(). Yes, I admit that is true, but there is no element that I want the new one added before. What do I do?

Update: I've tried null as the second arguement. It works in Mozilla, but now breaks in IE. I suspect that this is the correct way, but I agree with MS, this arguement should be optional. I don't agree with MS that they shouldn't support the standard, though. I'm still looking for a common answer.

Can't say much for Mozilla, but Opera & IE 6 work fine:

Code:

<html>
  <head>
    <title>Foo</title>
  </head>
  <body>
    <select id="mySelect">
    </select>
    <script type="text/javascript">
      myNewOption = document.createElement("option");
      myNewOption.text = "foo";
      myNewOption.value = 1;
      document.getElementById("mySelect").options[0] = myNewOption;
    </script>
  </body>
</html>

Try appendChild instead of add.

**Travis G** · Jan 26th, 2004, 02:47 PM

Code:

        document.getElementById("baseSelect").options[document.getElementById("baseSelect").options.length] = newOption;

This works in both. appendChild probably works, but I have to treat newOption as a Node and not an Element, so I have to set values and stuff differently.

Code:

var inputActive = document.createElement("input");
inputActive.type = "checkbox";
inputActive.checked = Boolean(arrBases[selectIndex][3] == 1);

Code:

var inputActive = document.createElement("input");
inputActive.type = "checkbox";
if (arrBases[selectIndex][3] == 1) {
     inputActive.checked = true;
}
else {
  inputActive.checked = false;
}

Neither of these work in IE, either.

You wouldn't believe all the things that don't work in IE

**nemaroller** · Feb 11th, 2004, 09:14 PM

Actually, I'm surprised at all the things that DO work in IE, that don't work in Netscape.

I know its not the politically correct stance, but I truly believe since IE controls 90%+ of the browser market, that I'm FAR more concerned getting tricky scripts to run in IE, than I would ever be for the 1 or 2 users that use Netscape /Mozilla.

And since I am not running a e-commerce site, anyone that can't use it, doesn't affect our model.

I wish M$ got their CSS working properly. damn lazy bastards.

sorry for the random blurt but it had to be said.

Maybe the Internet would be better off back in the days of Kermit and Xmodem.

Just text and nothing else.

Those were easily agreed upon standards.

Uhm... such as?

**CornedBee** · Feb 12th, 2004, 12:27 PM

Nah, lynx sucks. Use links2

**Travis G** · Feb 12th, 2004, 01:48 PM

Odd, I have to launch IE to start a new thread here at VBForums. This is something new. The new thread image doesn't appear in Mozilla. It may be because of my user style sheet, which is supposed to not display banner ads from major distributors.

Well, for one, the onkeydown event.

**CornedBee** · Feb 13th, 2004, 04:56 AM

onkeydown works perfectly well in Mozilla.

**nemaroller** · Feb 13th, 2004, 08:18 AM

I didn't test Mozilla (i'm sure it works there), but Netscape 6/7, it is broke.

"Unfortunately, the onkeydown event is broken in Netscape 6 and 7, so this solution does not work in those browsers."

does that include 7.1? the newest one?

if so, that's very very silly of them.

I didn't realize there was that much of a difference between Netscape and Mozilla. I guess they share Gecko and nothing more.

**Acidic** · Feb 13th, 2004, 08:42 AM

put it this way, Mozilla always works, as long as you've got correct code and use a new version of Mozilla (or Mozilla FireFox), it'll work.

**CornedBee** · Feb 13th, 2004, 11:02 AM

Let's put it this way, Netscape is usually based on outdated Mozilla builds. 6 was based on 0.9, 7 on 1.0.1, 7.1 on 1.4. Current version is 1.6.
