I'm not sure what I've done wrong, but I can't seem to get the palette sample to work. I've made an add in from the code here:http://help.autodesk.com/view/fusion360/ENU/?guid=GUID-c97b8ed2-e1da-11e6-af4c-3417ebc87622
I didn't make any changes, but when I try to use the 'send info to Palette' button I get the error pictured. When I click the 'click to send info to Fusion' button on the palette nothing happens. What could cause this if I didn't edit the sample code?
Thank you for reporting this. I can reproduce it and have found the problems. The good news is that the problem isn't with Fusion but was with the sample code. I made a couple of last minute changes as I was publishing it and apparently I broke it. I've fixed it in the help system so it will be available with the next Fusion update. Until then here's the updated html and py source.
palette.html
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<p id='p1'>Click the button below or use the "Send info to HTML" command in the ADD-INS panel.</p>
<button type='button' onclick='sendInfoToFusion()'>Click to send info to Fusion</button>
<br /><br />
</body>
<script>
function sendInfoToFusion(){
var args = {
arg1 : "Sample argument 1",
arg2 : "Sample argument 2"
};
adsk.fusionSendData('send', JSON.stringify(args));
}
window.fusionJavaScriptHandler = {handle: function(action, data){
try {
if (action == 'send') {
// Update a paragraph with the data passed in.
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>
