这是我需要能够向现有LOV添加静态值的JavaScript代码.当页面加载并将静态值过去的航班"添加到指定的选项时，将执行此JavaScript代码.感谢大家的帮助.

This is the JavaScript code that I needed to be able to add a static value to my existing LOV. This JavaScript code executes when the page is loaded and added the static value "Past Flights" to the specified option. Thank for the help everyone.

$('#P100_FLIGHT_LOV2 option[value="55S"]').before('<option value="Past">--- Past Flights ---</option>');
