Topic awaiting preservation: Read txt/ascii with JScript? (Page 1 of 1)

Hi guys,

I was just wondering whether it is possible to parse css files with JScript as if the css file was just a plain ascii text file?

I want to do this because the standard stylesheet parsing functions in JScript and Javascript will skip any css values IE doesn't understand (replaces them with 'UNKNOWN') - I don't want it to do this - I want to read the whole file as plain text. I'm pretty sure javascript couldn't do it, but I know there are some extra JScript functions that allow stuff like this so I'm hoping that there will be something can do exactly this.

Thanks guys,

Jon

AFAIK, there is no way you can read data from a file with Javascript unless you load a text file into an iframe then use innerHTML() to get at it.

Might have some more luck with JScript, but I know noffin about that. Sorry.

Not with javascript - I know there is no way with javascript.

But JScript is a whole different kettly of fish - it has many proprietry and advanced functions that javascript doesn't have and since I only need it to work with IE it's perfect.

Locally JScript can be used to read any ascii based format with something like this:

<script>
var fso, ts, s;
fso = new ActiveXObject("Scripting.FileSystemObject");
ts = fso.OpenTextFile("styles.css", 1);
s = ts.ReadAll();
document.write(s);
</script>

But firstly it pops up an IE warning prompt and then a antivirus security box - it doesn't work however from files on a server - although it can work fine as a complete serverside solution but I can't be doing that.

The prompt problem is because of the ActiveX, so I'm wondering if there is another way to do it with JScript.

Thanks anyway tho,

Jon

You may be able to load and parse it using an xmlHTTP object (via the .innerHTML property perhaps.)

You can infact read data from a textfile using jscript, if that file is a js-file.
It's not much of a bother saving information as objects in a js-file.
- What's wrong with you people anyway??

You can use a built in IE behavior, the "download" behavior. For instance, try this:

var sheet, links = document.getElementsByTagName('link');

for(var i=0; i<links.length; i++) {

   sheet = links[i];

   // if(  ) { // possibly some checks here...

      sheet.addBehavior('#default#download');

      sheet.startDownload(sheet.href, parseCSSText);

   // }

}



function parseCSSText(css) {

   alert(css); // jay!

}

Then you'll have to filter everything with heaps of regular expressions you're entering a "world of pain", so to speak. :P but it's a fun challenge.

Cameron, how do you do that. Do you simply make an Iframe, and then do
alert(document.getElementById("myIframe").innerHTML)
on it? I've tried that, and other functions such as alert(document.getElementById("myIframe").src) work, but his simply returns nothing. Any ideas?

EDIT: Sorry, found the problem: should be
alert(myIframe.document.body.innerHTML)
