Question about document.layers
How can I use it to display a popup or an alert box?

Hi,

I've been having problems the past few days getting a page to look okay to NN4 users. Finally, I decided that making a page compatible with NN4x AND using CSS requires more knowledge than I have, and way too much time. But, I'm getting enough NN4 visitors that I feel I need to take them into account, at least by letting them know why the page doesn't look right to them.

Someone said that only NN4x recognizes document.layers. So my plan was to display an explanatory popup or an alert box using document.layers. I have a few questions about how I should procede.

First, is there any kind of popup stopper that works with NN4? A popup would really be my preference over an alert box, but with so many popup stoppers in use these days I wasn't sure if a popup was best. If no (or few) popup stoppers work with NN4, I'll probably skip the alert box and work out some sort of popup situation.

So, if I decide on a popup, how can I call it using document.layers? I've used a popup script before that I like, but it uses an external .js file. Can I use document.layers to call that file?

And, if I end up deciding on an alert box after all, is there any way to include links to modern browser upgrades in the alert box, and set it so the alert only shows up once per browser session?

If someone can answer some or all of these questions, or provide an alternative solution, I would greatly appreciate it. My knowledge of javascript is nominal, so I'm really relying on this forum for instructions! :)

Thanks,

Matthew

Yes, pop-up blockers do work with Netscape 4. Many will not block the pop-up windows that are activated by a user action -- but quite a few will be that heavy-handed.

And since you will probably be automatically opening the new window, an Alert may be a more universal solution for you. No, you won't get an active hyperlink in there, but at least you can be sure to inform your users about what's happening.

All you need is:

if (document.layers) {
alert("Your Message Here")
}

or if you go with a pop-up window, call your pop-up function instead of the Alert:

if (document.layers) {
yourPopupFunction(yourParameters)
}
