hello guys, i'm new at ros. i want to subscribe a topic to a webpage. i tried to do the following tutorial but subscribe part doesnt work. Should i add a label or something to view the subscription to the html file? here is the tutorial: http://wiki.ros.org/roslibjs/Tutorial...
You need to save the html code to a file, like ros_test.html. Then open that file in your browser. You should see Simple roslib Example. Check your Web Console for output. To see the console (in the Chrome browser): menu, more tools, javascript console. Other browsers will have something similar.
To have the HTML update: In the body section, add something with an Id:
<body>
<h1>Simple roslib Example</h1>
<p id="abc">Test</p>
</body>
In listener.subscribe(function(message), add
document.getElementById("abc").innerHTML = message.data;
