Download a copy button  in Document Library - SP2013

One of my  Client  asked to download a Document , All Users don't have permission to access Ribbon and  download  a copy of   Document, so it this way we can create  button for  Download a copy of Document

 user was asking on How to add “DOWNLOAD A COPY” button in document library COLUMN?

And to answer this question, I did a bit of research and came up with below solution

First step is to add a new column to the document library. I named it as “Download a copy”

Ensure to add the new column as the last column in the View.

Now go back to the view, then edit page. Now add a new Script Editor webpart and paste below code

1 2 3 4 5 6 7 8 9 10 11

<script type="text/javascript"> function runAfterEverythingElse(){ var elementArray = document.getElementsByClassName("ms-vb-lastCell"); var idArray = document.getElementsByClassName("ms-listlink"); for(var i = 0; i < elementArray.length; i++) {     elementArray[i].innerHTML = '<a unselectable="on" href="javascript:;" onclick="window.open(\''+ idArray[i]['href'] + '\')" class="ms-cui-ctl-large " aria-describedby="Ribbon.Documents.Copies.Download_ToolTip" mscui:controltype="Button" role="button" id="Ribbon.Documents.Copies.Download-Large"><span unselectable="on" class="ms-cui-ctl-largeIconContainer"><span unselectable="on" class=" ms-cui-img-32by32 ms-cui-img-cont-float"><img unselectable="on" alt="" src="/_layouts/15/1033/images/formatmap32x32.png?rev=31" style="top: -409px; left: -35px;"></span></span><span unselectable="on" class="ms-cui-ctl-largelabel">Download a<br>Copy</span></a>'; }  } _spBodyOnLoadFunctionNames.push("runAfterEverythingElse");  </script>

Click Ok, and stop editing the page. Final result
