Hi,
I am using WebSockets in my B4J app and I am trying to work out how to trigger a sub in my B4J project from a HTML page function.
Looking though the tutorial you need to put a sub in the B4J app like:
Sub btnCalc_Click (Params As Map)
Result.SetText("Hello World")
End Sub
And using a button in the HTML page:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Web App Hello World!</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<link rel="stylesheet" type="text/css" href="index.css" />
<script src="/b4j_ws.js"></script>
</head>
<body>
<h1>Web App Hello World!</h1>
<p id="plog"></p>
<div id="maindiv">
First Number: <input id="text1" type="text"></input><br/>
Second Number: <input id="text2" type="text"></input><br/>
<button id="btncalc">Calculate</button><br/>
<p id="result"></p>
</div>
<script>
//connect to the web socket when the page is ready.
$( document ).ready(function() {
b4j_connect("/ws");
});
</script>
</body>
Everything is working fine so far..
But rather than using a button to trigger the code in the B4J app (btnCalc_Click) is there a way to run the sub in the B4J from a function in the HTML page ?
<button onClick="RunFunction();">Click Me</button>
function RunFunction()
{
// What code can I use here to run the Sub in my B4J app?
}
