EVENT HANDLER:  onload
onload = myJavaScriptCode

Event handler for Image, Layer and Window.

The onload event handler executes the specified JavaScript code or function on the occurance of a Load event. A Load event occurs when the browser finishes loading a window or all the frames in a window.

The onload event handler uses the following Event object properties.

type - this property indicates the type of event.
target - this property indicates the object to which the event was originally sent.
width - when the event is over a window, not a layer, this represents the width of the window.
height - when the event is over a window, not a layer, this represents the height of the window.

The following example shows the use of the onload event handler to display a message in the text box.

Code:
<body onload = "changeVal()" >
<form action="" method="POST" id="myForm" >
<input type="text" name="myText" >

<script type="text/javascript" language="JavaScript">
s1 = new String(myForm.myText.value)

function changeVal() {
     s1 = "Greetings!"
    myForm.myText.value = s1.toUpperCase()
}

</script>
</form>
</body>
