Notes

  • This property applies only to windows that are created by using the showModalDialog method.
  • When a script calls the showModalDialog method, it suspends execution until the modal dialog box is closed. As a result, the script cannot use the dialogWidth property to change the appearance of the modal dialog box. To control the appearance of the modal dialog box, use script in the file loaded by the sURL parameter or use the value of the sFeatures parameter to specify the desired settings.
  • The default unit of measure is px
  • The value can be an integer or floating-point number, followed by an absolute units designator (cm, mm, in, pt, or pc), or a relative units designator (em, ex, or px). For consistent results, specify the dialogHeight and dialogWidth in pixels when you design modal dialog boxes.
