It's not a bug, it's a feature! <g>


Joachim, you don't know how I struggled with this after IE4/Mac came out.

I had done an elaborate set of pages that had to have client-side

scritping and had exactly the same problem.


There are two ways around it.

1) Do a document.write only for MacIE users that either gives them the

following message or provides a link to click that takes them to page

where you give them this message:


"If you are receiving error messages, this is because IE4 for the

Mac is a piece of crap. You can permanently disable these error alerts by

going to Preferences and selecting Web Content from the list on the left.

On the right panel, change the setting for Active Scripting Alerts to

None. From now on, pages will come up correctly with no

alerts."


2) You can also use JavaScript to write the VBScript code, which

eliminates the error messages so no message to IE4/Mac users is

needed.


My code for this looks like this:


-- First, design a browser detect that pulls out IE FOR WINDOWS 95/NT --

not the Mac. In my case, the function is called "isIE" Then,

after that function, I put this:



 if(isIE) {

document.write("<SCRIPT LANGUAGE='VBScript'\>\n");

document.write("Sub m1_Change()\n");

document.write("call relateItems\n");

document.write("End Sub \n");


document.write("Sub m2_Change()\n");

document.write("call gotoPage\n");

document.write("End Sub\n");


document.write("Sub Window_onLoad() \n");

document.write("call addHeadings\n");

document.write("End Sub\n");

document.write("</SCRIPT\>\n");

}


The "\n" is necessary at the end of each

line, or it causes VBScript parsing errors. However, instead of \n you

could also use DOCUMENT.WRITELN, I suppose. I found this worked better,

though.


Using JS to write VBS is tricky. Sometime the code won't parse on Windows

afterward, so make sure you test, test, test.


Good luck and e-mail me PRIVATELY if you need more help.
