How to Use OnFocusScript and OnBlurScript Properties


Both the OnBlurScript and OnFocusScript properties (used with the FieldInfo object) will set or retrieve a script to execute, but they use different triggers.



  • OnBlurScript
    When the focus moves from the specified field to another location, OnBlurScript sets or retrieves the script to execute.

  • OnFocusScript
    When the focus moves from another location to the specified field, OnFocusScript sets or retrieves the script to execute.


Code Example for OnFocusScript and OnBlurScript


The following example includes a Click Here button:



  • click on the button once and OnFocusScript is called.

  • click any where off the button and OnBlurScript is called.

Dim FSO, strPath, outputFile, inputFile

intResult = oTK.CopyForm(0, 0)


If intResult <> 1 Then


ErrorHandler "CopyForm", intResult
