Get parameter from current url How can I get parameter i.e node id from URL in views link path . Eg. - suppose in taxonomy term's view I am giving field name's custom link path is "document/getParameterFromCurrentURL/{‌{tid}}". where suppose getParameterFromCurrentURL  is variable or etc so how can i get id from current url in getParameterFromCurrentURL.
You could try adding a "Global: Null" contextual filter to your Views display, configured to "Provide default value" with type "Content ID from URL". 

The Null filter type doesn't change the output of your view. But it would make the Node ID available as a replacement pattern.
