This is done by attaching an onmouseover event to an Input Text component that displays the information:

In the above image:

• The Text Input component has orderNumber as server reference
• The component has an onmouseover event attached to it
• The exposed function help attached to the onmouseover event contains the following code:

var $event : Objectvar $webForm : 4D.WebForm
$webForm:=Web Form$event:=Web Event$componentRef:=$event.caller
If ($event.eventType="onmouseover")  // event is onmouseover $webForm["helpOn_"+$componentRef].show()  // show the help on "orderNumber" by showing the text component with reference "helpOn_orderNumber" Else $webForm["helpOn_"+$componentRef].hide()  // hide the help on orderNumberEnd if
