The examples below illustrate how to integrate our Knob control into a web page, set a control property through the page loaded event, and handle a Knob control event.

1. This example sets the position of the Knob to 75 when the page is loaded.

  Copy code

<html>
<head>
<title>Knob Control</title>
<script type="text/javascript">
  function SetPosition()
  {
    iKnobX1.Position = 75;
  } 
</script>
</head>
<body onload="SetPosition()">
<OBJECT ID="iKnobX1"
CLASSID="clsid:C5412DC7-2E2F-11D3-85BF-00105AC8B715">
</OBJECT>
</body>
</html>
  
2. This example shows connection and implementation of the OnPositionChangeUser event for the Knob control.

  Copy code

<html>
<head>
<title>Knob Control</title>
<script type="text/javascript" for=iKnobX1   
  event="OnPositionChangeUser()">
 <!--
    iKnobX1_OnPositionChangeUser();
 //-->  
</script>
<script type="text/javascript">
 function iKnobX1_OnPositionChangeUser()
 {
   Text1.value = iKnobX1.Position;
 }
</script>
</head>
<body>
<OBJECT ID="iKnobX1"
CLASSID="clsid:C5412DC7-2E2F-11D3-85BF-00105AC8B715">
</OBJECT>
<input type="text" id="Text1"> 
</body>
</html>
