How to Uninstall a Module in Magento - Reinstall Magento Module and Run Install Script

If you want Magento to reinstall the module and re-run any database setup, take a look at the core_resource table. Delete your module from this table and DROP any tables that the module had created. Clear Magento’s cache and the module will re-install. The mysql4-install-X.X.X.php files will only be run once by Magento. By changing the version value in your XML config (Namespace/Module/etc/config.xml), you’re telling Magento which install file it should use:

		var ph = $(this).parents('li').height();
		var mh = Math.ceil((ph-ah) / 2);
                // may choose to use margin-top - depends on your case
                // for debugging
                console.log('a position: ' + i + 
					'a height: ' + ah + 
					'li height:' + ph +

A Javascript Playground - JsFiddle

JsFiddle is a playground for web developers, a tool which may be used in many ways. One can use it as an online editor for snippets build from HTML, CSS and JavaScript. The code can then be shared with others, embedded on a blog, etc. Using this approach, JavaScript developers can very easily isolate bugs. We aim to support all actively developed frameworks - it helps with testing compatibility.
