| Script | Result |
|-|-|
| `alert("Hello World"); ` | Displays a window with Hello World and an OK button. Note: Rather than use JavaScript alert(), for a cleaner look, you can display an error on the form itself with thee showFieldMsg() and hideFieldMsg() methods. For more information, see [Display field messages](https://www.servicenow.com/docs/BHRJGhxbQ1dJG~kn9hYVxw "Rather than use JavaScript alert(), for a cleaner look, you can display an error on the form itself. The methods showFieldMsg() and hideFieldMsg() can be used to display a message just below the field itself."). Note: The client script alert option is not available for use with Automated Test Framework (ATF). |
| `confirm("Hello World");` | Displays a window with Hello World? and OK and Cancel buttons. |
| `g_form.showFieldMsg("field_name", "Hello World", "error");` | Adds Hello World below the specified field in a red error message. |
| `g_form.hideFieldMsg("field_name");` | Hides the most recent message for the specified field. |
