细节

jsparse.php file is a maintenance script for testing JavaScript validity using JSMin+'s parser. This is a useful feature to run parsing/syntax check on JavaScript files.

Options/Arguments

This script takes the filenames of the files to be validated as arguments, separated by spaces.

Usage

php maintenance/run.php jsparse filename

In MediaWiki version 1.39.10 and earlier, you must invoke maintenance scripts using php maintenance/scriptName.php instead of php maintenance/run.php scriptName.

	var $rightDiv = $("<div>");
	
	$longList.append($leftDiv, $rightDiv);
