UV colour depending on the number ie None Low Medium High Very High

Do you need to declare uvword before the first if statement? Sorry, I'm not very au fait with javascript.

Yes it would be best to do that...

Code: Select all

var uv = rawdata[45];
var uvword;
if (uv=="0"){ uvword="None";} else
if (uv=="3"){ uvword="<span ...

All true but I don't think it is the cause of failing.
Maybe @dazza could elaborate on what exactly fails? Does it show anything in the UVone element or does it show erroneous something?
As you compare strings is that truly the content of the rawdata or is it e.g. "0 " with as result the if statements all fail and you get an empty string in the html element. If uncertain add a console.log statement after each if-clause to see something.

Or go to stackoverflow.

Sorry ive just just upload a test page to my site as i was doing all off line....

so if you can take a look you can see now ? and for the output nope nothing and the rawdata is the realtime.txt line 44 but it 45 as it count from 1

or JavaScript is fun and fluid and lets you get away with all sorts of stuff. TypeScript - boo!

Dazza, I do not see any content on your test page, but wow! That is some refresh rate - every 20 milliseconds!

You problem now is the UV value you are comparing against seems to be the UVI * 100. The value currently is 160, so that falls through to your last clause where uvword=""

That's why it is so popular. I am a fan!

woops yh just spotted that 20 milliseconds

and the UV in the realtime.txt reads like 1.5

so maybe like this

if (uv=="1.5"){ uvword="<span style=\"border: solid 1px; color: black; background-color: #A4CE6a;\">&nbsp;Low&nbsp;</span>";} else

[HansR]

that's why I only touch it when necessary

To the point image

[mcrossley]

Your script is reading field 45 for the UV, that is the Solar Rad value, UV is in field 43.

im going bye this

https://cumuluswiki.org/a/Realtime.txt

44 13 UV Index <#UV>


but ive have tried 43/44 but it doesn't seem to work

The Wiki uses 1 relative field field numbers, your code uses 0 relative, it should be 43.

You next problem is you if statements, they are doing compares against specific values. I think what you intended was to use >= rather than ==

I'd also drop the use of strings in your compares and use exact numeric comparisons rather than relying on JS laxness that Freddie loves!
Maybe another day for that.

Oh go on I'll do it, just to close the thread!

Code: Select all

var uv = rawdata[43] * 1;
var uvword;	
if (uv<=0){ uvword="None";} else
if (uv<=3){ uvword="<span style=\"border: solid 1px; color: black; background-color: #A4CE6a;\">&nbsp;Low&nbsp;</span>";} else
if (uv<=6){ uvword="<span style=\"border: solid 1px; color: black; background-color: #FBEE09;\">&nbsp;Medium&nbsp;</span>";} else
if (uv<=8){ uvword="<span style=\"border: solid 1px; color: black; background-color: #FD9125;\">&nbsp;High&nbsp;</span>";} else
if (uv<=11){var uvword="<span style=\"border: solid 1px; color: #FFFFFF; background-color: #F63F37;\">&nbsp;Very&nbsp;High&nbsp;</span>";} else
{ uvword="eek!";}
$("#UVone").html(uvword);
