Trying to modified the palette / python code to :
1. Click the palette html button to activate the python script
2. python script to get some data from the Components
3. python feed the data back to the palette
4. palette to display the returned message.
added bonus would be to have the palette window display when the add-on is run.
Problem - palette displays, but when clicking on the button, it loops with the number returned from python updating all the time.
I stripped out the code for the "Send Info to HTML" add-on dropdown menu, as I want the python script to return the required info once the palette html button is clicked.
The palette code is :
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<p>Click the button below to send data to Fusion.</p>
<button type='button' onclick='sendInfoToFusion()'>Click to send info to Fusion</button>
<p id='p1'>Ready to run.</p>
<br /><br />
</body>
<script>
function sendInfoToFusion(){
// arg1 = 'ReadVolumes' will tell the python script which data I want returned to display on the palette.
var args = {
arg1 : "ReadVolumes",
};
adsk.fusionSendData('send', JSON.stringify(args));
}
window.fusionJavaScriptHandler = {handle: function(action, data){
try {
if (action == 'send') {
document.getElementById('p1').innerHTML = data;
}
else if (action == 'debugger') {
debugger;
}
else {
return 'Unexpected command type: ' + action;
}
} catch (e) {
console.log(e);
console.log('exception caught with command: ' + action + ', data: ' + data);
}
return 'OK';
}};
</script>
</html>
The python code is :
