class Browser method .msgBox()

Browser is the Apps Script service.

.msgBox() is the method name you will see after a dot in your code.

What it does

Shows a message box with OK or other buttons.

Why it's used

  • Quick OK dialog in simple scripts without custom HTML.
  • Confirm an action in older or lightweight workflows.

Common errors

  • Forgetting parentheses on msgBox. Write Browser.msgBox(), not Browser.msgBox or msgBox by itself.
  • Skipping dots between chained calls. Each step needs a dot, like Browser.msgBox().
  • Adding spaces where they do not belong. Write Browser.msgBox(), not Browser .msgBox(), Browser.msgBox (), or Browser . msgBox().
  • Wrong capitalization. Use Browser and msgBox, not browser or msgbox.
