Hi Folks,
I have two issues:
1- I have written following code a code that works in IE but not in firefox. Please see code below. JavaScript version is 1.3. Both browsers should be able to run the script? -
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN">
-
<html>
-
<style type="text/css">
-
table {border-collapse: collapse; }
-
TEXTAREA {width:300px; height:200px; border: 0; overflow:hidden;}
-
td {width:30px;padding: 0; margin: 0; border: 1px solid gray;}
-
</style>
-
-
<script Language="javascript">
-
-
function setBorderBold(x)
-
{
-
document.getElementById(x).style.border="0.20em black solid";
-
}
-
-
function setBorderToStandard(x)
-
{
-
document.getElementById(x).style.border="0.05em solid gray";
-
}
-
-
-
</script>
-
-
<body>
-
<form>
-
<table bordercolor="gray"><tr><td id="myid1"><TEXTAREA name="thetext" id="textarea1" onfocus="setBorderBold('myid1')" onblur="setBorderToStandard('myid1')"></textarea></td><td id="myid2"><TEXTAREA name="thetext" maxwidth="400em" id="textarea1" onfocus="setBorderBold('myid2')" onblur="setBorderToStandard('myid2')"></textarea></td></tr></table>
-
</form>
-
</body>
-
</htm>
-
2- Second issue is just a genaral question: which javaScript version is the best to use cosidering the diversity of browsers and incompatibility problems?
Or is there something like a "javaScript Plugin" for browsers, so that each browser could run any version of Javascript provided the plugin is installed?Maybe a silly question, but am a beginner :)
Regards
Bu

1 - you should validate your html, this will certainly solve most problems. (e.g. use <script type="text/javascript">)
2 - don't rely on javascript version. the easiest way is to check for the existance of the function/feature you want to use.
example - if (document.addEventListener()) {
-
// some code
-
}
-
else if (document.attachEvent) {
-
// some code for IE
-
}
-
else {
-
// any error handling (silent fail)
-
}

If only, if only! Unfortunately, browsers don't always follow standards, some add their own proprietary features, and there are many bugs. Welcome to the frustrating world of cross-browser coding. As Dormilich pointed out, you don't specify the JavaScript version (though JavaScript does have versions). If you want to support older browsers that may not support the method that you want to use, use object/feature detection to avoid errors.

Hi all,
I've written this little piece of code, which doesn't seem to work in
Mozilla 1.5. I haven't tried it on other Gecko browsers, but I've found
some indication that Netscape 6+ has the same problem. Internet Explorer 6
and Opera 7 have no problems with it.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
