If you’ve gone to an AJAX version of the Carter Lake template so your values dynamically update (thanks, Pinto!), here’s a function for generating the wind direction label using an array.
Instead of parsing the wind direction value and assigning text labels here:
//Winddirection ... val = x.responseText.split(' ')[3]; if (val >= 349 && val <= 360) val = "N" if (val >= 0 && val < 12) val = "N" if (val >=12 && val < 34) val = "NNE" if (val >=34 && val < 56) val = "NE" if (val >= 56 && val < 79) val = "ENE" if (val >= 79 && val < 101) val = "E" if (val >= 101 && val < 124) val = "ESE" if (val >= 124 && val < 146) val = "SE" if (val >= 146 && val < 169) val = "SSE" if (val >= 169 && val < 191) val = "S" if (val >= 191 && val < 214) val = "SSW" if (val >= 214 && val < 236) val = "SW" if (val >= 236 && val < 259) val = "WSW" if (val >= 259 && val < 281) val = "W" if (val >= 281 && val < 304) val = "WNW" if (val >= 304 && val < 326) val = "NW" if (val >= 326 && val < 349) val = "NNW" document.getElementById("ajaxwinddir").innerHTML = " " + val; document.getElementById("ajaxwindicon").innerHTML = ' <img src=./images/winddir/' + val + '.gif width="14" height="14" alt="Wind from ' + val + '" title="Wind from ' + val + '"></img>';
add a function to the top of the AJAX script section:
function windDir ($winddir) // Take wind direction value, return the // text label based upon 16 point compass { $windlabel = new Array("N", "NNE", "NE", "ENE", "E", "ESE", "SE", "SSE", "S", "SSW", "SW", "WSW", "W", "WNW", "NW", "NNW"); return $windlabel[Math.floor(((parseInt($winddir) + 11) / 22.5) % 16 )]; }
Then replace the wind direction section with:
[color=blue]` //WIND DIRECTION …
val = windDir(x.responseText.split(’ ')[3]);
document.getElementById("ajaxwinddir").innerHTML = " " + val;
document.getElementById("ajaxwindicon").innerHTML = ' <img src="./images/winddir/' + val + '.gif" width="14" height="14" alt="Wind from ' + val + '" title="Wind from ' + val + '">';`[/color]
