The onchange event activates when the value of an input element has changed.  The event can be specified as a JavaScript expression or the name of a JavaScript function.  

If an expression is used, the JavaScript keyword this refers to the element; this.value can retrieve the new value.  

If the name of a function is used, the function will receive 2 parameters when called: 

  • The browser event object
  • A reference to the element


The following can be placed on a Slider widget to display the slider's value within a nearby Label widget.
