Hi

I am struggling to find an error in my simple script.
The script works as intended in Firefox 3.6.4 , but the tab always says "loading"

In IE8 I get a permissions error, and no result.

I've spent 2 days tryng to isolate the bug, and would be really grateful if someone could show me where I'm being stupid!

See
Many thanks,

Graham

looking at the markup I would say this is a problem
Code: 
<select name="..." size="...">
<option>Red
<option>Green
<option>Yellow
<option>Alternating
<option>Random
you are not closing the tags. it should be
Code: 
<select name="..." size="...">
   <option>Red</option>
   <option>Green</option>
   <option>Yellow</option>
   <option>Alternating</option>
   <option>Random</option>
</select>

Hi Jason,

Many thanks, no, unfortunately that's not it.

I've closed the tags now, but still the same code error.

All the best,

Graham

[tt]
//////////////////////////////////////////////////
// Start to write the document
//////////////////////////////////////////////////
[red]document.open();[/red]
document.write("<html><head><style type=\'text/css\' media=\'all\'>@import \'lel.css\';</style></head><body><h1>Titan matrix creator</h1><br><br><table border=12 bordercolor=black cellpadding=0 cellspacing=0 rules=none frame=box>");

[blue]// etc etc [/blue]

/////////////////////////////////////////////////
// Now close the HTML document
//////////////////////////////////////////////////
document.write("</table>");
document.write("<br><br><input type=\'button\' value=\'Back\' onClick=\'history.go(-1)\'></body></html>");
[red]document.close();[/red]
[/tt]
But, I must say, that is the kind of thing that make people very uneasy. As an exercise, I guess it is okay.

it also may be that you are escaping the single quotes within a double quoted string. you only need to escape characters when the quotes are the same.
examples
Code: 
document.write("double \" quote")
document.write('double " quote')
document.write('single \' quote')
document.write("single ' quote")
echoing tsuji. document.write is usually a sign there is a better way to generate the html. I'm not a css guru, but you should be able to build the image using css sprites within a div (not table required).

the concept works like this:
1. create a single css image containing the black background and a single colored "light"
2. depending on the width and height selected by the user set the width and height of the div tag. the background is set to to the selected image and repeated vertically and horizontally.

Hi Folks,

Still no joy, I've done all recommendations, except the css, as it should work with html, but will look at css once the bug has been found.

Will not write in IE, beyond the 1st <tr> tag.

The updated version with your recommendations is now available on my original link.

Thanks

My post above is based on this statement that the script works as intended in firefox, if it is not working at that level, .open() and .close() will not help.
I visit the page with Firefox. I cannot confirm it is working though. I may miss something on what to do with the page. But, I won't insist.

Hi tsuji,

Thank you, the Firefox is working OK now.

But still no result in IE.

There is no output at all.

Regards,

Graham

Since you mention something related to "input", I would say when you script the select element, you've to put the value attribute to the options, even if you're intended to be the same as the "text" of it. Using text as a proxy for value would not work cross-browser. I mean this.

><option>Red</option>
[tt]<option [red]value="Red"[/red]>Red</option>[/tt]

etc...

Hi tsuji,

Not that - thanks for all your suggestions, though:)

The problem now is only in IE.

Ok. I look a bit into your page source. You use everywhere client-side selectedIndex only, hence, no, it won't help you that way with proper value attribute.

Here is what you've to do with the script.
[1] Put a string variable anywhere above the occurence of document.open().
[tt] var s="";[/tt]
[2] Comment out document.open() and document.close() at their present location.
[3] Replace all document.write(...) by simply building the s instead.
[tt] [red]//[/red]document.write("some string");
s+="some string";[/tt]
[4] [highlight]At the end[/highlight] of the function, do all the document building
[tt] document.open();
document.write(s);
document.close();[/tt]

another option... use jquery to reference the DOM, get the values, build the result and append to the DOM. there are still too many nuancies with javascript and browsers to write raw javascript. a library like jquery will abstract the browser differences for you.
