dScript User Manual v2.15

The last thing to add is a call to startAJAX() after the web page has been loaded. Do this by

modifying the <body> tag like this:

The new html page looks like this:

<!DOCTYPE HTML>

<html>

<head>

<title>Dweb Simple Test Page</title>

</head>

<button id="Rly1" onmousedown="newAJAXCommand('dscript.cgi?Rly1=2');">Yard

Lights</button>

<br> Temperature is

function ajaxUpdate()

{

document.getElementById('Rly1').style.backgroundColor =

(getValue('Rly1')=='1') ? 'rgba(255,0,0,0.2)' : 'rgba(0,0,255,0.2)';

}

</script>

</body>

</html>

The final items we'll add to this simple web page is a couple of variables, the temperature from

the on-board sensor and the input power supply voltage.

Add the following immediately below the button tag.

Temperature: <div id="Temperature">?</div>

DC Voltage: <div id="DCvolts">?</div>

Then add the following in the ajaxUpadte function immediately below the existing line.

document.getElementById('Temperature').innerHTML =

Number(getValue('Temperature')/10).toFixed(1);

document.getElementById('DCvolts').innerHTML =

Number(getValue('Volts')/10).toFixed(1);

In the dScript program we need to declare the two analogue ports, the two variables

Temperature and Volts and add a couple of lines in the do loop to calculate the temperature

and voltage from the incoming ADC values.
