			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>
