How to install Javascript 1.5 in Firefox

slsscoot · 03-28-2008, 05:48 PM

I utilize a website that needs javascript 1.5 or later installed. My version of firefox has 1.4.

How can I update it? I'm not having much luck on my own.

What distribution and what version of firefox do you have?

Firefox 2.0.0.13

You don't need to install anything for JavaScript. If you mean Java, then read the instructions for installing the JRE on Sun's website.

I need JavaScript 1.5 or higher in order to be able to use a website for school. When the site checks my browser's javascript version, it says I have 1.4 installed and I need 1.5, so I DO need to upgrade JavaScript and NOT java.

javascript has been supported since firefox 1.5. It sounds rather dubious that you don't have it. Are you sure that js is enabled?

OK, go here: http://www.java.com/en/download/linux_manual.jsp
Download the rpm, and follow the instructions (link is on the same page)
You are done!

The guy is talking about the JavaScript version of Firefox, not Java.

JavaScript 1.4 I can hardly imagine, that would be years old.

Code:

<script language="Javascript1.4">
jsver = 1.4;
</script>
<script language="Javascript1.5">
jsver = 1.5;
</script>
<script language="Javascript1.6">
jsver = 1.6;
</script>
<script language="Javascript1.7">
jsver = 1.7;
</script>
<script type="text/javascript">
document.write('<p><b>Javascript version ' + jsver
+ ' supported<\/b><\/p>');
</script>

Drop this into a file, save it as whatever.html and open it in your Firefox and it should say 1.7 for all more or less recent versions of Firefox.

Firefox 3 will include JavaScript 1.8

I think I know what your problem is. See the next post.

Let me guess: You are trying to use WebTycho? Even if it is not WebTycho this info should help. The problem is not the version of JavaScript in your browser. The problem is the flakey code used by WebTycho to detect the version. Your browser already has 1.5 or higher which what is required. The following link will provide some details on taking care of it:

Note that this applies to Ubuntu, Fedora and possibly others. I had the problem with Fedora 8. If you replace your existing browser with the one downloaded directly from Firefox (the basic fix) you mau need to install the following RPM or equivalent package:

compat-libstdc++-33-3.2.3-47.3.i386.rpm

I hope this helps.

You are ABSOLUTELY correct....WebTycho.

I'll try your suggestions.

Thanks
