UV reading from number to word

[mcrossley]

Almost there, this should do it...

Code: Select all

<script type="text/javascript">
if (<#UV> >= 11) {
document.write('Extreme');
} else if (<#UV> >= 8) {
document.write('Very High');
} else if (<#UV> >= 6) {
document.write('High');
} else if (<#UV> >= 3) {
document.write('Moderate');
} else if (<#UV> >=  1) {
document.write('Low');
} else if (<#UV> === 0) {
document.write('No Reading');
} else {
document.write('Invalid');
}
</script>

My alternative would be...

Code: Select all

<script type="text/javascript">
var lookupVal = [0,1,1,2,2,2,3,3,4,4,4,5,5,5,5,5,5],
    lookupTxt = ['No reading','Low','Moderate','High','Very high','Extreme'];
document.write(lookupTxt[lookupVal[<#UV>]] || 'Invalid');
</script>

Hi MarystownWeather2012,

I would go with the top piece of code in Mark's last post!

I'm glad that I could help,

William

Thanks all I appreciate all your help on this.

Coward!

Ok, I don't find that funny, at all. I'm not a coward...

OK, conservative then - go with the lower code and work out what it is doing. Two lookups instead of up to six compares sounds much more efficient to me.

Hi Mark,

Yes, I am conservative!

Ok, I understand what that code is doing. Yes, I do think two lookups instead of six sounds much more efficient, too! Sorry, to make you think I was a coward! But, at first I didn't realize I was coward, until now!

Thanks,

William

Maybe you both can team up and help me with this.

I am trying to add line "Watches/Warnings/Other" with webtag <#currcond> to my iCumulus page under the Current forecast line.

Any help would be appreciated.

That should be under another topic.

When your head clears try this for your UV

Code: Select all

<td>UV Index</td>

<td>
<script type="text/javascript">

var lookupVal = [0,0,0,1,1,1,2,2,2,3,3,3,4,4,4,4,4],
	lookupCol = ["#00FF00", "#FFFF00", "#FFA500", "#FF0000", "#FF66FF"],
	lookupTxt = ['Low','Medium','High','VERY HIGH','EXTREMELY HIGH'];
	if(lookupVal[<#UV>] >= 0){
		document.write("<span style='background-color: " +lookupCol[lookupVal[<#UV>]]+ ";'>&nbsp;<#UV>/16&nbsp;" +lookupTxt[lookupVal[<#UV>]]+ "&nbsp;</span>");
	}else{
		document.write('unknown');
	}
</script>

@ william ..... Don't even think about it

I'm using a Davis station with UV reporting to 1 decimal place - the UK in winter gets little sun so every tenth of a unit counts

The original JS code didn't like this at all, so I've tweaked it using the Math.round() function use a full figure for calculations to determine the text and colour, but still reports the UV as a decimal.

Code: Select all

<script type="text/javascript">
var UV = 12;
var lookupVal = [0,0,0,1,1,1,2,2,2,3,3,3,4,4,4,4,4],
   lookupCol = ["#00FF00", "#FFFF00", "#FFA500", "#FF0000", "#FF66FF"],
   lookupTxt = ['Low','Medium','High','VERY HIGH','EXTREMELY HIGH'];
   if(lookupVal[Math.round(<#UV>)] >= 0){
      document.write("<span style='background-color: " +lookupCol[lookupVal[Math.round(<#UV>)]]+ 

";'>&nbsp;<#UV>/16&nbsp;" +lookupTxt[lookupVal[Math.round(<#UV>)]]+ "&nbsp;</span>");
   }else{
      document.write('unknown');
   }
</script>
</td>

Great thread guys.
