Thanks Gary, I was completely overthinking it and forgetting about
gauge-data.txt! I've added a small script in index.html.tmpl to pull the
forecast string out of the gauge-data.txt json string, works a treat.
<td><p class="text-dark"><dfn data-info='Short term hyperlocal forecast for
Lerwick'>Short Term Forecast</dfn>:</p></td>
<td><p class="text-dark" id="fcst"></p></td>
<script>
const xmlhttp = new XMLHttpRequest();
xmlhttp.onload = function() {
const gaugeData = JSON.parse(this.responseText);
document.getElementById("fcst").innerHTML = gaugeData.forecast;
}
xmlhttp.open("GET", "ss/gauge-data.txt");
xmlhttp.send();
</script>
Thanks again,
Rory
